While Loop in SQL Server(TSQL)

By creating a loop, we can perform certain operations as long as this loop continues.

We can use While Loop as follows. As long as @testvariable is less than 10, operations within the BEGIN and END blocks in the WHILE block will be executed repeatedly.

DECLARE @testvariable int=1
WHILE(@testvariable<10)
BEGIN
Select @testvariable
SET @testvariable+=1;
END

DECLARE @testvariable int=1

WHILE(@testvariable<10)

BEGIN

Select @testvariable

SET @testvariable+=1;

END

To use While Loop with a Cursor, I suggest you read the article “Cursor Usage in SQL Server“.
