hi
i have to prevent an item to reappear based on the preconditions.
when user create a schedule the gameid is going inside the DayCountGame table

INSERT DayCountGame Values(@sVideoItemID,1,@gameid,@SlotStartTime,@ShowId)

when user next create the schedule i want to block the game to reappear in the same show where showid is matched. @showid is a dynamic parameter

i have done the join but i am not sure how can i add the condition if @showid = GB.showid
then apply this condition AND GB.[GameID]  is null

LEFT JOIN DayCountGame GB
ON VI.[GameID] = GB.[GameID]

AND GB.[GameID]  is null



CREATE TABLE [dbo].[DayCountGame](
	[VideoItemID] [int] NOT NULL,
	[SelectCount] [smallint] NOT NULL,
	[GameID] [int] NULL,
	[sd] [datetime] NOT NULL,
	[ShowID] [int] NULL
) ON [PRIMARY]

maybe

LEFT JOIN DayCountGame GB
ON VI.[GameID] = GB.[GameID]
where (@showid = GB.showid and GB.[GameID]  is null)
or @showid <> GB.showid
