Here is another example on how to use a CONTINUE statement to skip the remaining statements and continue the next iteration:
-- Printing first 7 Sundays in 2000 DECLARE @date DATETIME; DECLARE @count INT; SET @date = '1999-12-31'; SET @count = 0; WHILE DATEPART(YEAR, @date) < 2001 BEGIN SET @date = DATEADD(DAY, 1, @date); IF @count = 7 BREAK; IF DATENAME(WEEKDAY, @date) <> 'Sunday' CONTINUE; PRINT CONVERT(VARCHAR(40),@date,107); SET @count = @count + 1; END GO Jan 02, 2000 Jan 09, 2000 Jan 16, 2000 Jan 23, 2000 Jan 30, 2000 Feb 06, 2000 Feb 13, 2000
