CREATE procedure checkAvailable

@BookingNumber varchar(20), @RetVal varchar(10) output

as

if EXISTS (SELECT 1 from Bookings where BookingNumber=@BookingNumber )

set @RetVal='Yes'

else

set @RetVal='No'

return
GO

this proc is not returning 'No' ever
always returns 'Yes' only....
why?

Try like this and see if there's any difference

CREATE procedure checkAvailable

@BookingNumber varchar(20), @RetVal varchar(10) output

as

if (SELECT COUNT(*) from Bookings where BookingNumber=@BookingNumber )>0

set @RetVal='Yes'

else

set @RetVal='No'

GO

alter procedure checkAvailable

@BookingNumber varchar(20), @RetVal varchar(10) output

as

if EXISTS (SELECT 1 from t2 where colb=@BookingNumber )

set @RetVal='Yes'

else

set @RetVal='No'

return
GO

declare @v1 varchar(10)
execute checkAvailable 6,@RetVal=@v1 output
select @v1
