Syntax of for-loop in SQL Server

Question

What is the syntax of a for loop in TSQL?

Answer 1

Simple answer is NO !!.

There is no FOR in SQL, But you can use WHILE or GOTO to achieve the way how the FOR will work.

WHILE :

DECLARE @a INT = 10

WHILE @a <= 20
BEGIN
    PRINT @a
    SET @a = @a + 1
END

GOTO :

DECLARE @a INT = 10
a:
PRINT @a
SET @a = @a + 1
IF @a < = 20
BEGIN
    GOTO a
END

I always prefer WHILE over GOTO statement.
