IN VS EXISTS VS JOIN, performance
 
05:04
This video demonstrates the performance effects of using an exists clause instead of an IN clause, also it shows how we can update a simple sub query having an IN clause with an EXISTS or JOIN statement. It also shows that joining would consider the null data, where as an IN clause would neglect null values.

Oracle SQL.Подзапрос EXISTS является наиболее сложным типом подзапроса в SQL. Но мы попробуем разобраться, здесь очень важно Осознать, что подзапрос EXIST Является предикатом, возвращает нам либо истину либо ложь, то есть в подзапрос EXIST это критерий того, будет на экран выведена данная строка либо нет.

Merge: Databases for Developers #17

Sometimes when adding rows to your database need update-if-exists, insert-if-not-exists logic. Aka an upsert. You could write this as separate update and insert statements.

DYNAMIC SQL WITH EXECUTE IMMEDIATE IN ORACLE PL/SQL WITH EXAMPLE
 
21:53
The audio and video now synced. Ever tried creating a table inside a PL SQL block, or a function or a procedure? If yes, then you would know that it would raise an error, as DDL statements are not allowed inside a PL/SQL Block. So the solution to such a case, where you want to generate tables, or sequences or want to execute any DDL statement on the fly, then use synamic sql. Dynamic SQL statment will allow you to create state statements on the fly and then you can execute them using the execute immediate statement. This video tutorial demonstrates on this topic of using synamic sql with execute immediate in a PL/SQL block.

SQL Server except operator
 
05:14
sql except example sql except operator example sql server except example sql server except order by sql server except clause SQL Server except operator In this video we will discuss SQL Server except operator with examples. EXCEPT operator returns unique rows from the left query that aren’t in the right query’s results. Introduced in SQL Server 2005 The number and the order of the columns must be the same in all queries The data types must be same or compatible This is similar to minus operator in oracle Let us understand this with an example. SQL Script to create the tables Create Table TableA ( Id int primary key, Name nvarchar(50), Gender nvarchar(10) ) Go Insert into TableA values (1, 'Mark', 'Male') Insert into TableA values (2, 'Mary', 'Female') Insert into TableA values (3, 'Steve', 'Male') Insert into TableA values (4, 'John', 'Male') Insert into TableA values (5, 'Sara', 'Female') Go Create Table TableB ( Id int primary key, Name nvarchar(50), Gender nvarchar(10) ) Go Insert into TableB values (4, 'John', 'Male') Insert into TableB values (5, 'Sara', 'Female') Insert into TableB values (6, 'Pam', 'Female') Insert into TableB values (7, 'Rebeka', 'Female') Insert into TableB values (8, 'Jordan', 'Male') Go Notice that the following query returns the unique rows from the left query that aren’t in the right query’s results. Select Id, Name, Gender From TableA Except Select Id, Name, Gender From TableB To retrieve all of the rows from Table B that does not exist in Table A, reverse the two queries as shown below. Select Id, Name, Gender From TableB Except Select Id, Name, Gender From TableA You can also use Except operator on a single table. SQL script to create tblEmployees table Create table tblEmployees ( Id int identity primary key, Name nvarchar(100), Gender nvarchar(10), Salary int ) Go Insert into tblEmployees values ('Mark', 'Male', 52000) Insert into tblEmployees values ('Mary', 'Female', 55000) Insert into tblEmployees values ('Steve', 'Male', 45000) Insert into tblEmployees values ('John', 'Male', 40000) Insert into tblEmployees values ('Sara', 'Female', 48000) Insert into tblEmployees values ('Pam', 'Female', 60000) Insert into tblEmployees values ('Tom', 'Male', 58000) Insert into tblEmployees values ('George', 'Male', 65000) Insert into tblEmployees values ('Tina', 'Female', 67000) Insert into tblEmployees values ('Ben', 'Male', 80000) Go Except operator on a single table Select Id, Name, Gender, Salary From tblEmployees Where Salary ]= 50000 Except Select Id, Name, Gender, Salary From tblEmployees Where Salary ]= 60000 Order By clause should be used only once after the right query Select Id, Name, Gender, Salary From tblEmployees Where Salary ]= 50000 Except Select Id, Name, Gender, Salary From tblEmployees Where Salary ]= 60000 order By Name Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/sql-server-except-operator.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/adsbygoogle-window.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
