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.

How to use EXISTS / NOT EXISTS Logical Operator in SQL Server -  SQL Server / TSQL Tutorial Part 125
 
09:41
What is Exists / Not Exists Logical Operator in SQL Server Exists returns TRUE if a subquery contains any rows. EXISTS is used when we want to test for the existence of rows specified by a subquery. 1) EXISTS will return TRUE if subquery contains any rows. That is right, if our subquery will return any rows and we have used EXISTS, the outer query is going to return all rows. 2) Use EXISTS and Join with SubQuery Link to scripts used in SQL Server / TSQL Tutorial Video http://www.techbrothersit.com/2016/06/how-to-use-exists-logical-operator-in.html Check out our website for Different SQL Server, MSBI tutorials and interview questions such as SQL Server Reporting Services(SSRS) Tutorial SQL Server Integration Services(SSIS) Tutorial SQL Server DBA Tutorial SQL Server 2016 DBA Tutorial SQL Server / TSQL Tutorial ( Beginner to Advance) http://www.techbrothersit.com/

What to choose for performance   SubQuery or Joins   Part 62

Text version of the video http://csharp-video-tutorials.blogspot.com/2013/01/what-to-choose-for-performance.html Slides http://csharp-video-tutorials.blogspot.com/2013/09/part-62-what-to-choose-for-performance.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 What to choose for performance - SubQuery or Joins According to MSDN, in sql server, in most cases, there is usually no performance difference between queries that uses sub-queries and equivalent queries using joins. For example, on my machine I have 400,000 records in tblProducts table 600,000 records in tblProductSales tables The following query, returns, the list of products that we have sold atleast once. This query is formed using sub-queries. When I execute this query I get 306,199 rows in 6 seconds Select Id, Name, Description from tblProducts where ID IN ( Select ProductId from tblProductSales ) At this stage please clean the query and execution plan cache using the following T-SQL command. CHECKPOINT; GO DBCC DROPCLEANBUFFERS; Go DBCC FREEPROCCACHE; GO Now, run the query that is formed using joins. Notice that I get the exact same 306,199 rows in 6 seconds. Select distinct tblProducts.Id, Name, Description from tblProducts inner join tblProductSales on tblProducts.Id = tblProductSales.ProductId Please Note: I have used automated sql script to insert huge amounts of this random data. Please watch Part 61 of SQL Server tutorial, in which we have discussed about this automated script. According to MSDN, in some cases where existence must be checked, a join produces better performance. Otherwise, the nested query must be processed for each result of the outer query. In such cases, a join approach would yield better results. The following query returns the products that we have not sold atleast once. This query is formed using sub-queries. When I execute this query I get 93,801 rows in 3 seconds Select Id, Name, [Description] from tblProducts where Not Exists(Select * from tblProductSales where ProductId = tblProducts.Id) When I execute the below equivalent query, that uses joins, I get the exact same 93,801 rows in 3 seconds. Select tblProducts.Id, Name, [Description] from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId where tblProductSales.ProductId IS NULL In general joins work faster than sub-queries, but in reality it all depends on the execution plan that is generated by SQL Server. It does not matter how we have written the query, SQL Server will always transform it on an execution plan. If sql server generates the same plan from both queries, we will get the same result. I would say, rather than going by theory, turn on client statistics and execution plan to see the performance of each option, and then make a decision. In a later video session we will discuss about client statistics and execution plans in detail.

UPDATE STATEMENT WITH JOIN IN ORACLE SQL
 
07:18
This video demonstrates how user can update data of a particular table(t1), based on the join condition with other table(t2). So it would be a easy way to ditch the for-loop, and check for the condition every time. What was to be achieved from the for-loop can be achieved with a single simple update statement. A simple trick to update data in table based on some conditional data in some another table, would help you to increase the performance of your code massively. For ex : UPDATE TABLE1 t1 SET COL1 = (SELECT COL FROM TABLE2 t2 where t1.col = t2.col);

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.

LNNVL FUNCTION IN ORACLE SQL
 
09:11
This video is the 5th video in the series of 'working with null', this video explains the working of the lnnvl function in oracle sql with simple and easy to understand example. LNNVL provides a concise way to evaluate a condition when one or both operands of the condition may be null. The function can be used only in the WHERE clause of a query. It takes as an argument a condition and returns TRUE if the condition is FALSE or UNKNOWN and FALSE if the condition is TRUE. LNNVL can be used anywhere a scalar expression can appear, even in contexts where the IS [NOT] NULL, AND, or OR conditions are not valid but would otherwise be required to account for potential nulls. Oracle Database sometimes uses the LNNVL function internally in this way to rewrite NOT IN conditions as NOT EXISTS conditions. In such cases, output from EXPLAIN PLAN shows this operation in the plan table output. The condition can evaluate any scalar values but cannot be a compound condition containing AND, OR, or BETWEEN.
