SQL:Max/Min Functions
 
03:38
In this tutorial, you'll learn how to use max min functions in sql queries. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

SQL with Oracle 10g XE - Using the MIN, MAX, and AVG Functions
 
04:48
In this video I use the MIN, MAX, and AVG functions to generate the minimum, maximum, and average vales of a column. When using these functions be sure to include the column you wish to perform the function on in parenthesis. You can also use the WHERE keyword to limit the function to only those records that meet your criteria. This video is part of a series of videos with the purpose of learning the SQL language.

PLS-2: My First PL/SQL Program
 
11:34
For Full Course Experience Please Go To http://mentorsnet.org/course_preview?course_id=5 Full Course Experience Includes 1. Access to course videos and exercises 2. View & manage your progress/pace 3. In-class projects and code reviews 4. Personal guidance from your Mentors Goal is to write your first PL/SQL program. The basic program unit in PL/SQL is the block. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords partition the block into a declarative part, an executable part, and an exception-handling part. Example of a Block DECLARE bonus NUMBER(8,2); emp_id NUMBER(6) := 100; BEGIN SELECT salary * 0.10 INTO bonus FROM employees WHERE employee_id = emp_id; Exception When NO_DATA_FOUND THEN null ; END; This is a typical PL/SQL block where 10% of salary is selected and stored on a temp variables bonus. If for some reason there is no employee with empid = 100 then the control will come to exception area and the code in the exception area will be executed. These blocks can be entirely separate or nested one within another. The basic units (procedures and functions, also known as subprograms, and anonymous blocks) that make up a PL/SQL program are logical blocks, which can contain any number of nested sub blocks. Therefore, one block can represent a small part of another block, which in turn can be part of the whole unit of code. Anonymous Blocks Anonymous blocks are unnamed blocks. They are declared at the point in an application where they are to be executed and are passed to the PL/SQL engine for execution at run time. You can embed an anonymous block within a pre-compiler program and within iSQL*Plus or Server Manager. Triggers in Oracle Developer components consist of such blocks. Subprograms Subprograms are named PL/SQL blocks that can accept parameters and can be invoked. You can declare them either as procedures or as functions. Generally use a procedure to perform an action and a function to compute a value. You can store subprograms at the server or application level. Using Oracle Developer components (Forms, Reports, and Graphics), you can declare procedures and functions as part of the application (a form or report) and call them from other procedures, functions, and triggers (see next page) within the same application whenever necessary. Note: A function is similar to a procedure, except that a function must return a value.

Database Design 33 - Cardinality
 
07:35
Donate!: http://bit.ly/DonateCTVM2. Cardinality is the maximum number of connections a row of one table can have with row(s) of another table. This is basically just a fancy word to describe the two options: 1, or many. Designing the cardinality shows us whether the relationship is a one-to-one relationship or a one-to-many relationship. In the event of a logical many-to-many relationship, the cardinality would be best designed as two separate one-to-many relationships with the intermediary table in the middle (see my video over many-to-many relationships).

Should I Learn Oracle or MySQL?
 
02:20
Should I learn Oracle or MySQL? MySQL is a popular open source database, but Oracle seems like the default database I see in use. Oracle is more expensive to implement and to train in. The certifications are like Microsoft's examinations, in that the classes and tests cost more. Then I need to go with MySQL. Not so fast. Popular should equal more job opportunities. MySQL has stronger database authentication based on the person's location. However, Oracle has corporate support to assist you with any problems you have. Which database do you think is better? Oracle does have a number of superior database management tools like rman, dataguard, internal job scheduling and queues. Oracle also has a more mature stored procedure language compared to MySQL. Stored procedures make it a lot easier to add verification logic and corrections to your database, instead of reprogramming the application that relies on the database. MySQL originally didn't have stored procedures or the rich programming environment Oracle did. However, MySQL is catching up. I know that a lot of companies like Oracle's hot backups so that restorations are faster in case of database failure, and the Real Application Clusters that lets your users search several servers at once is a good value. All of that is why Oracle is so often used, especially by big companies. Where is MySQL used? MySQL is free to a lot of non-profits and non-commercial groups. So it is popular at small charities and schools. It sounds like I need to learn Oracle just to gain access to the higher paying jobs, since non-profits don't pay much. Or you could learn Microsoft SQL. I'm not that desperate. Oh, come on. You could manage Microsoft databases on Microsoft Windows servers if you learn Microsoft SQL. I'd rather work for minimum wage at a non-profit with MySQL than MSSQL.

There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

Grouping Functions in SQL Query Like AVG,SUM,MAX,MIN
 
04:03
SQL COUNT (): This function returns the number of rows in the table that satisfies the condition specified in the WHERE condition. If the WHERE condition is not specified, then the query returns the total number of rows in the table. For Example: If you want the number of emps in a particular department, the query would be: SELECT COUNT (*) FROM emp WHERE deptno = 10; If you want the total number of emps in all the department, the query would take the form: SELECT COUNT (*) FROM emp; SQL DISTINCT(): This function is used to select the distinct rows. For Example: If you want to select all distinct department names from emp table, the query would be: SELECT DISTINCT deptno FROM emp; To get the count of emps with unique name, the query would be: SELECT COUNT (DISTINCT name) FROM emp; SQL MAX(): This function is used to get the maximum value from a column. To get the maximum salary drawn by an emp, the query would be: SELECT MAX (salary) FROM emp; SQL MIN(): This function is used to get the minimum value from a column. To get the minimum salary drawn by an emp, he query would be: SELECT MIN (salary) FROM emp; SQL AVG(): This function is used to get the average value of a numeric column. To get the average salary, the query would be SELECT AVG (salary) FROM emp; SQL SUM(): This function is used to get the sum of a numeric column To get the total salary given out to the emps, SELECT SUM (salary) FROM emp;

over partition by in sql server 2008 sql server over clause partition partition by clause in sql server 2008 over partition by clause in sql In this video we will discuss the power and use of Over clause in SQL Server. The OVER clause combined with PARTITION BY is used to break up data into partitions. Syntax : function (...) OVER (PARTITION BY col1, Col2, ...) The specified function operates for each partition. For example : COUNT(Gender) OVER (PARTITION BY Gender) will partition the data by GENDER i.e there will 2 partitions (Male and Female) and then the COUNT() function is applied over each partition. Any of the following functions can be used. Please note this is not the complete list. COUNT(), AVG(), SUM(), MIN(), MAX(), ROW_NUMBER(), RANK(), DENSE_RANK() etc. Example : SQl Script to create Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Gender nvarchar(10), Salary int ) Go Insert Into Employees Values (1, 'Mark', 'Male', 5000) Insert Into Employees Values (2, 'John', 'Male', 4500) Insert Into Employees Values (3, 'Pam', 'Female', 5500) Insert Into Employees Values (4, 'Sara', 'Female', 4000) Insert Into Employees Values (5, 'Todd', 'Male', 3500) Insert Into Employees Values (6, 'Mary', 'Female', 5000) Insert Into Employees Values (7, 'Ben', 'Male', 6500) Insert Into Employees Values (8, 'Jodi', 'Female', 7000) Insert Into Employees Values (9, 'Tom', 'Male', 5500) Insert Into Employees Values (10, 'Ron', 'Male', 5000) Go Write a query to retrieve total count of employees by Gender. Also in the result we want Average, Minimum and Maximum salary by Gender. This can be very easily achieved using a simple GROUP BY query as show below. SELECT Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender What if we want non-aggregated values (like employee Name and Salary) in result set along with aggregated values You cannot include non-aggregated columns in the GROUP BY query. SELECT Name, Salary, Gender, COUNT(*) AS GenderTotal, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender The above query will result in the following error : Column 'Employees.Name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause One way to achieve this is by including the aggregations in a subquery and then JOINING it with the main query as shown in the example below. Look at the amount of T-SQL code we have to write. SELECT Name, Salary, Employees.Gender, Genders.GenderTotals, Genders.AvgSal, Genders.MinSal, Genders.MaxSal FROM Employees INNER JOIN (SELECT Gender, COUNT(*) AS GenderTotals, AVG(Salary) AS AvgSal, MIN(Salary) AS MinSal, MAX(Salary) AS MaxSal FROM Employees GROUP BY Gender) AS Genders ON Genders.Gender = Employees.Gender Better way of doing this is by using the OVER clause combined with PARTITION BY SELECT Name, Salary, Gender, COUNT(Gender) OVER(PARTITION BY Gender) AS GenderTotals, AVG(Salary) OVER(PARTITION BY Gender) AS AvgSal, MIN(Salary) OVER(PARTITION BY Gender) AS MinSal, MAX(Salary) OVER(PARTITION BY Gender) AS MaxSal FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/over-clause-in-sql-server_29.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

12 of 15 SQL Basics with Oracle - Aggregate (grouping) functions and the GROUP BY clause
 
09:33
This video explains the GROUP BY clause and some of the aggregate functions: sum, count, average, maximum, minimum, count(distinct ...), etc. An example of using an aggregate function would be to group students by major and only show the number of students in each major, not individual student information. (12 of 15) There is also an "Advanced SQL" series. (Search for "databasemec" for tutorials using SQL Server.)

Windows 32-Bit Hardware Requirements Requirement Value Physical memory (RAM) 1 GB minimum Virtual memory Double the amount of RAM Disk space Total: 4.76 GB See Table 2-3 for details. Processor 550 MHz minimum (On Windows Vista, 800 MHz minimum) Video adapter 256 colors See Also: "Configuring Disk Storage for Oracle Data Files and Recovery Files" "Creating Directories for Oracle Data Files or Recovery Files" "Preparing Disk Groups for an Automatic Storage Management Installation" "Installing with Minimum Memory Requirements" 2.1.2 Hardware Component Requirements for Windows x64 The following table lists the hardware components that are required for Oracle Database on Windows x64. Windows x64 Hardware Requirements Requirement Value Physical memory (RAM) 1 GB minimum Virtual memory Double the amount of RAM Disk space Total: 5.22 GB See for details. Processor AMD64, or Intel Extended memory (EM64T) Video adapter 256 colors 2.1.3 Hard Disk Space Requirements for Windows 32-Bit This section lists system requirements for Windows platforms that use the NT File System (NTFS). Oracle recommends installing Oracle components on NTFS. NTFS allows for strong security of database files, trace files, incident data, and so on, stored in the Oracle home. The NTFS system requirements listed in this section are more accurate than the hard disk values reported by the Oracle Universal Installer Summary window. The Summary window does not include accurate values for disk space, the space required to create a database, or the size of compressed files that are expanded on the hard drive. The hard disk requirements for Oracle Database components include 32 MB required to install Java Runtime Environment (JRE) and Oracle Universal Installer on the partition where the operating system is installed. If sufficient space is not detected, installation fails and an error message appears. .----------------------------------------------------------------------------------------------------------. video courses- list of playlist : tips and trics link► https://www.youtube.com/playlist?list=PLOfLYVXrwqXrI5jvwUEi6N13QR4xCj2k2 command prompt commands: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXobXGUdGk6JhzyQ216dNiQL oracle sql: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXqoUWCoh4cARGDW13SofDO- c programming: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXrZ_Ub8EXeLY7YP1YxhoJzf .-----------------------------------------------------------------------------------------------------------. watch more videos: learn oracle sql online overview tutorail : https://www.youtube.com/watch?v=Dfesgj4w8QA&t=8s how to fix or repair a corrupted usb flash drive or cd card using command prompt: https://www.youtube.com/edit?video_id... how to copy a folder using cmd: https://www.youtube.com/watch?v=Lblhb... how to move a folder using cmd: https://www.youtube.com/watch?v=YFfHZ... how to dell files in cmd: https://www.youtube.com/watch?v=3-lqg... how to make and remove directory: https://www.youtube.com/edit?video_id... how to change color and title in cmd: https://www.youtube.com/edit?video_id... how to change directory in command prompt: https://www.youtube.com/watch?v=SmLYx... .-----------------------------------------------------------------------------------------------------------. social media links: join our group: ► https://www.facebook.com/groups/24299... ► Follow on Google+: http://[email protected] ► Follow on Twitter: https://twitter.com/@rananavi4766669 :

We can use deep reinforcement learning to optimize a SQL database, and in this video we'll optimize the ordering of a series of SQL queries such that it involves the minimum possible memory/computation footprint. Deep RL involves using a neural network to approximate reinforcement learning functions, like the Q (quality) function. After we frame our database as a Markov Decision Process, I'll use Python to build a Deep Q Network to optimize SQL queries. Enjoy!

SQL Aggregate functions like SQL MAX, SQL MIN, SQL COUNT And AVERAGE function
 
09:22
http://learningsqlserver2008.com SQL Aggregate Functions are necessary to summarize numerical data in a SqL Server database. We have already looked at other transact SQl statements like SELECT and UPDATE SQL statements. Those typically are used to return rows of data that matches the criteria in the WHERE clause. SQL statements using aggregate functions like MIN, COUNT, AVG, SUM or MAX however return just one value after sql server has already applied the aggregation and summarized the data. In this manner MS 2008 aGgregate fUnctions perform their operation across multiple rows of data. For today's discussion we are going to look at AdventureWorks2008 sample database in SQL Server 2008.

How to Create an user in Oracle with minimum grants/privileges we need to connect as SYSDBA lets ceate an user test you can see the user is created : But can it connect? lets open a new session we can see it lacks create session priv. so, we grant the create session privilege to user test lets test Its connecting. But is it able to create a table ,lets check. it lacks the ability to create table. SO lets give the privilege. lets test again the create table command. its throwing error regarding no Privilege on users tablespace . But we have given USERS as the default tablespace to test(user). So whats the problem? The problem is there is not quota defined for user test. lets give some quota like "10MB" or UNLIMITED , we will giev 10MB NOw let us test. So we can see that we now have sufficient / minimum privileges for the user test. Hope this will help in understanding the concept behind user creation

I have written a small sql code to find out all database constraints. Just be sure you have dba permission, otherwise you might not view all constraints. To see constraints separately for dba and user you can use user or dba instead of all, like user_constraints or dba_constraints, user_cons_columns, dba_cons_columns. I have used all_ to find out everything instead in a single query.

The Summary window does not include accurate values for disk space, the space required to create a database, or the size of compressed files that are expanded on the hard drive. The hard disk requirements for Oracle Database components include 32 MB required to install Java Runtime Environment (JRE) and Oracle Universal Installer on the partition where the operating system is installed. If sufficient space is not detected, installation fails and an error message appears. .----------------------------------------------------------------------------------------------------------. video courses- list of playlist : tips and trics link► https://www.youtube.com/playlist?list=PLOfLYVXrwqXrI5jvwUEi6N13QR4xCj2k2 command prompt commands: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXobXGUdGk6JhzyQ216dNiQL oracle sql: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXqoUWCoh4cARGDW13SofDO- c programming: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXrZ_Ub8EXeLY7YP1YxhoJzf .-----------------------------------------------------------------------------------------------------------. watch more videos: learn oracle sql online overview tutorail : https://www.youtube.com/watch?v=Dfesgj4w8QA&t=8s how to fix or repair a corrupted usb flash drive or cd card using command prompt: https://www.youtube.com/edit?video_id... how to copy a folder using cmd: https://www.youtube.com/watch?v=Lblhb... how to move a folder using cmd: https://www.youtube.com/watch?v=YFfHZ... how to dell files in cmd: https://www.youtube.com/watch?v=3-lqg... how to make and remove directory: https://www.youtube.com/edit?video_id... how to change color and title in cmd: https://www.youtube.com/edit?video_id... how to change directory in command prompt: https://www.youtube.com/watch?v=SmLYx... .-----------------------------------------------------------------------------------------------------------. social media links: join our group: ► https://www.facebook.com/groups/24299... ► Follow on Google+: http://[email protected] ► Follow on Twitter: https://twitter.com/@rananavi4766669 :

Oracle 12c PL/SQL Security New Features - Session 5 of 8 - The New Inherit Privileges Privilege
 
06:47
Learn the Oracle Database 12c Inherit Privileges Privilege. Demonstration and Examples. There's a whole new privilege. The inherit privileges privilege. We indeed inherit any privileges privileged. That's just in privileged of course. Any privileges - system privileges, any privileges is an object privilege or new type objects. We can now assign privileges, grant privileges on users. It limits the owner's inheritance of privileges from the invoker. Oracle Corporation is presumably reasonably happy with the way definer's rights code works and definer's rights code as I demonstrated can be highly dangerous. That hasn't really changed in the current release except is will see with the ability to grant roles to code because in invoker's rights we've got huge differences and that's the inheriting of privileges privilege. If you don't have the inheritance enabled, any attempt to execute invoker's rights code will fail because the definer will not be in able to inherit the rights of the invoker. So I'm going to go straight in to do it and then go through the rest of the slides so we can see the sort of issue. Let me lose 11g and go to 12c. What I shall do is create my low privileged user or drop user dev. I don't think he exists. He doesn't. So I'll create my low privileged user. Grant create session, create procedure, select any table to dev identified by dev. It's the same mechanism I use. The same command I use in 11g. I'm creating a developer with a bare minimum that he needs to do his job, which is writing code that lets people query the database. Then log on as him, comm dev/dev and create my procedure. I'll create a version of the code, create or replace procedure list_emp, author ID current user. Invoker's rights code. Remember, this gives my low privilege user dev the ability to insert something horrible in his code which shall then be executed with the invoker's rights. We create the procedure. Now connect / as sysdba - I'll be the highest possible person there is - set server output on and run the code. Execute dev.list_emp looking for the CLARKS. I can't do it. Even as user sys, I can't run that because of the lack of this new privilege. I can correct the situation. I can grant inherit privileges on user sys - which of course one would never normally do - to dev. So I'm now giving my low privilege user the ability to inherit the privileges of user sys when we are running invoker's rights code. And having done that, the code now succeeds. That's the general principle. Without this inherit any privileges code all that doesn't have any privileges privilege, all your invoker's rights code is now blocked. It simply won't run until you grant that privilege to your trusted user. So without inheritance the invoker's rights code will fail. This privilege is in fact granted by default in 12.1 when a user is created. I believe this is purely for backward compatibility. So you don't have to worry about all your codes ceasing to function the moment you have to upgrade but there's no guarantee that this situation will remain as we go through 12.2, 12.3. Also in upgrade I haven't had the time to test comprehensively every possible method of upgrade but certainly this simple test I've done so far, the privilege does appear to be being granted and we can see it. If we look at who's been granted this privilege so far Select grantee, table_name, privilege from dba_tab_privs where privilege like inherit and we see that straight out of the box inherit privileges on a number of users have been granted to public. They have been granted to public. So if I create a brand new user, I grant connect to jw identified by jw, we will see that in the current release - there he is - inherit has beeen granted to public. In the current release by default, your code will continue to function and Oracle often does this with their [05:46 inaudible] with powerful new features. By default, it's configured so there's no change and in the next release it all changes. That's happened to a quite a few releases, quite a few new features, and it wouldn't surprise me if by the time we get to say 12.2 and certainly by the time we get to 13 this behavior changes. So plan for it and look at that privilege and see who it's been granted to and secure your systems. What you need to do is revoke all the inherit privileges grants that's there by default and then grant inherit any privileges very, very sparingly only to a very few trusted users and that should tighten up the danger of definer's inheriting invoker's rights. So a few trusted schemas, create the code in those schemas only and control this very tightly indeed.

Window functions in SQL Server
 
11:00
sql server window function example window function sql server example sql server rows range clause sql server rows between 1 preceding and 1 following In this video we will discuss window functions in SQL Server In SQL Server we have different categories of window functions Aggregate functions - AVG, SUM, COUNT, MIN, MAX etc.. Ranking functions - RANK, DENSE_RANK, ROW_NUMBER etc.. Analytic functions - LEAD, LAG, FIRST_VALUE, LAST_VALUE etc... OVER Clause defines the partitioning and ordering of a rows (i.e a window) for the above functions to operate on. Hence these functions are called window functions. The OVER clause accepts the following three arguments to define a window for these functions to operate on. ORDER BY : Defines the logical order of the rows PARTITION BY : Divides the query result set into partitions. The window function is applied to each partition separately. ROWSor RANGE clause : Further limits the rows within the partition by specifying start and end points within the partition. The default for ROWS or RANGE clause is RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW Let us understand the use of ROWS or RANGE clause with an example. Compute average salary and display it against every employee We might think the following query would do the job. SELECT Name, Gender, Salary, AVG(Salary) OVER(ORDER BY Salary) AS Average FROM Employees As you can see from the result, the above query does not produce the overall salary average. It produces the average of the current row and the rows preceeding the current row. This is because, the default value of ROWS or RANGE clause (RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) is applied. To fix this, provide an explicit value for ROWS or RANGE clause as shown below. ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING tells the window function to operate on the set of rows starting from the first row in the partition to the last row in the partition. SELECT Name, Gender, Salary, AVG(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS Average FROM Employees The same result can also be achieved by using RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING Well, what is the difference between ROWS and RANGE We will discuss this in a later video The following query can be used if you want to compute the average salary of 1. The current row 2. One row PRECEDING the current row and 3. One row FOLLOWING the current row SELECT Name, Gender, Salary, AVG(Salary) OVER(ORDER BY Salary ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING) AS Average FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/window-functions-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/window-functions-in-sql-server_7.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
