You are looking for the BREAK keyword.

a simple example to break out of what would otherwise be an endless loop:

--RAISERROR immediate message

--print error immediately in batch

DECLARE

@i INT,

@err VARCHAR(100)

--set @i=1

WHILE 0 = 0

BEGIN

SET @err = 'Progress So Far: Step ' + CONVERT(VARCHAR(30), ISNULL(@i, 1)) + ' completed.'

RAISERROR (@err,

0,

1) WITH nowait

WAITFOR delay '00:00:02'

SET @i=ISNULL(@i, 1) + 1

IF @i > 5

BREAK;

END

PRINT 'We Broke out of the loop!'

Are you sure you even need a cursor? Given that you want to break out of one I am guessing you are doing some sort of RBAR processing. Maybe the best way out of your cursor is to not have one at all.
