Using NOEXEC for conditional processing

NOEXEC allows you to do conditional processing even if you have GO statements splitting your script into batches.

DECLARE @runit INT
SET @runit =0

SET NOEXEC OFF

PRINT '1'

IF @runit = 0
 BEGIN
 PRINT  'Skipping Next Section'
 SET NOEXEC ON
 END
GO

PRINT '2'
GO
PRINT '3'
GO
PRINT '4'
GO

SET NOEXEC OFF
PRINT '5'
GO

Run the script twice, changing the value of @runit to 1 the second time. Cool huh?
