    @a_id int,
    @aname varchar(20), 
    @imgurl varchar(512), 
    @award_description varchar(1000), 
    @exchange_description varchar(1000),
    @keyword varchar(30),
    @Return int output
AS
BEGIN
    set @Return=1

    if @a_id=0 --添加
    begin
        if not exists (select * from ds_award where aname=@aname and IsDelete=0)
        begin
            insert into ds_award (aname, imgurl, award_description, exchange_description, keyword, create_time,IsDelete)
            values (@aname,@imgurl,@award_description,@exchange_description,@keyword,getdate(),0)
        end
        else
        begin
            set @Return=2 --已经存在同名礼物
            return
        end
    end
    else --编辑
    begin
        update ds_award set aname=@aname, imgurl=@imgurl, award_description=@award_description, exchange_description=@exchange_description,keyword=@keyword
        where a_id=@a_id
    end
    
    if @@error<>0
    begin
        set @Return=0
        return
    end
END

删除存储过程：

ALTER PROCEDURE [dbo].[ds_AwardDelete] 
    @a_id int,
    @Return int output
AS
BEGIN
    set @Return=1

    if (not exists (select * from ds_awardmgr where AID=@a_id and IsDel=0) and not exists (select * from ds_exchange where a_id=@a_id and [state]<>0))
    begin
        update ds_award set IsDelete=1 where a_id=@a_id
        delete from ds_exchange where a_id=@a_id
            
        if @@error<>0
        begin
            set @Return=0
            return
        end
    end
