sqlserver触发器实现插入时操作另一张表

#在mysql中变量直接这么定义就可以了
SET @VALUE = "111";

#在sql server中
declare @count int;
#并赋值
set @count =0;
#如果是查询，必须这么些
select @count = count(*) from WQ_MNINF_D_REAL where STCD=@stcd;

#mysql
IF @VALUE4=1 THEN
 INSERT INTO t_sca_history_data (METER_CODE,PARAM_CODE,DATA_VALUE,V_VALUE,DATE_TIME) VALUES
 (NEW.METER_CODE,NEW.PARAM_CODE,NEW.DATA_VALUE,NEW.V_VALUE,NEW.DATE_TIME);
END IF;

sql server
if(@count=0)
begin
 insert into WQ_MNINF_D_REAL select STCD,TYPE,UPPERVALUE,LOWERVALUE,TM,NT,@smid,@stnm,@prjcd,@pipcd from inserted;
end 

#inserted代表插入数据的那张临时表,同时还有deleted 这张用作删除数据的临时表
select STCD from inserted
#若只是把插入的数据插入另一张表，语句如下
insert into WQ_WWFINF_D_REAL select PRJCD,TM,INFL,SWWL,CWWL,OTPS,OTF,QOEC,PSPPS,NT FROM inserted;
#如果还有加点别的数据，可以这么做
insert into WQ_MNINF_D_REAL select STCD,TYPE,UPPERVALUE,LOWERVALUE,TM,NT,@smid,@stnm,@prjcd,@pipcd from inserted;

BEGIN
 declare @stcd varchar(30);
 declare @count int;
 declare @smid int;
