How To Stop a Loop Early with BREAK Statements in MS SQL Server?
Answer:
If you want to stop a WHILE loop early, you can use the BREAK statement in the loop statement block.
The tutorial exercise below shows you how to use a BREAK statement to stop a WHILE loop early:
-- Counting number of days in 2000
DECLARE @date DATETIME;
DECLARE @count INT;
SET @date = '2000-01-01';
SET @count = 0;
WHILE 1=1 BEGIN
IF DATEPART(YEAR, @date) > 2000 BREAK;
SET @count = @count + 1;
SET @date = DATEADD(DAY, 1, @date);
END
SELECT @count;
366
-- 2000 is a leap year!
