使用索引降低查询速度, 使用聚合函数 获取查询内容,  使用select 套select  加inner join 获取 链接数据

update 修改 数据  ,利用     ''update set 字段=from  表  inner join 表 on 字段=字段''                 的方式 进行修改

UPDATE  pc_forecast_mtl_type set  memo=(
SELECT a.memo from   MTL_STORE_AGE_DETAIL_INPUT a INNER JOIN pc_forecast_mtl_type b
on a.mtl_no=b.matcode ) ,
plandate =(
SELECT a.plandate from   MTL_STORE_AGE_DETAIL_INPUT a INNER JOIN pc_forecast_mtl_type b
on a.mtl_no=b.matcode where a.mtl_no=b.matcode

)  

update  a
set memo = b.memo
from  pc_forecast_mtl_type a inner join MTL_STORE_AGE_DETAIL_INPUT b
on a.matcode = b.mtl_no
where a.matcode =b.mtl_no

insert into  select  的使用

INSERT INTO #t_mtl(vndcode,matcode)

SELECT vndcode,matcode

FROM proprice_sheet 

WHERE (ISNULL(@vndcodehd,'') = '' OR vndcode = @vndcodehd)

  AND (ISNULL(@matcodehd,'') = '' OR matcode = @matcodehd)

  AND ISNULL(check_flag,) =
