please help me in this,how would i do some recursive statement in my stored procedure.
here is what i want
-- @requestcode will genereate some random string
set @requestcode = (SELECT substring(@username,0,3)+'-'+SUBSTRING(CONVERT(varchar(255), NEWID()), 0, 9))
-- then i want to check if the string generated is existing to 'sampletable'
select @requestcode from sampletable
-- if it is existing back to the @requestcode query until it is not existing
thanks in advance
