In this article, we will examine the loops and conditions we use in TSQL.
Conditions in TSQL:
IF Statement in SQL Server:
If the condition in the “IF” block is provided, we use it to perform operations between the “BEGIN” and “END” blocks.
You can see the example about IF Statement in the article named “IF Statement in SQL Server(TSQL)”
IF…ELSE Statement in SQL Server:
If the condition in the IF block is provided, operations between the BEGIN and END blocks are performed. If the condition in the IF block is not provided, the operations between the BEGIN and END blocks after the ELSE block are performed.
You can see the example about IF…ELSE Statement in the article named “IF…ELSE Statement in SQL Server(TSQL)”
CASE Statement in SQL Server:
Certain conditions are checked with the WHEN Statement when using the CASE Statement, and certain results are returned if the condition is met. We can define more than one WHEN Statement in a CASE Statement. If no conditions are met in the WHEN Statement defined in the CASE Statement, then the operations in the ELSE Statement are performed.
You can see the example about CASE Statement in the article named “CASE Statement in SQL Server(TSQL)”
Loops in TSQL:
While Loop:
By creating a loop, we can perform certain operations as long as this loop continues.
You can see the example about While Loop in the article named “While Loop in SQL Server(TSQL)“.
Also you can use Break and Continue Statements and GOTO Statement in While Loop. You can see the examples in the below articles.
“Break and Continue Statements in SQL Server(TSQL)”
“GOTO Statement in SQL Server(TSQL)”
