1 ------------------------------------
2 ------创建表值变量类型--------------
3 ------------------------------------
4 CREATE TYPE Ty_NewAreaGoods AS TABLE(
5 AreaID INT NOT NULL,
6 GoodsID INT NOT NULL
7 )
8 -------------------------------------
9 ----创键返回今天报价的数据-----------
10 ----根据有报价的地区获取参-----------
11 ----考报价地区以及交易品id-----------

28 ----调用存储过程----------------------
29 ----传入地区ID为1,2;交易品id=34-------

33 INSERT INTO @dt VALUES(2,34);

表值变量，with，update结合运用：
Update Code
1 CREATE PROC [dbo].[usp_UpdatePrice]
2 @dt Ty_NewAreaGoods READONLY
3 AS
4 BEGIN
5 SET NOCOUNT ON;
6 DECLARE @ERRORSUM SMALLINT ;
7 BEGIN TRAN;
8 SET @ERRORSUM=-1;
9 WITH temp_1 AS(
10 SELECT aa.AreaId,tt.GoodsID AS GoodsID FROM MD_Area aa,@dt tt WHERE aa.QuotationType=tt.AreaID
11 AND EXISTS(SELECT 0 FROM MD_Goods gg WHERE gg.TypeId = aa.GoodsTypeId AND gg.ID=tt.GoodsID)
12 UNION ALL
13 SELECT AreaID,GoodsID AS GoodsID FROM @dt
14 )
15 UPDATE pp SET pp.GuidePrice= 1001 FROM MD_Prices pp , temp_1 tt
16 WHERE pp.AreaID = tt.AreaId AND pp.GoodsId = tt.GoodsID
17 IF(@@ERROR<>0) GOTO ERROR_Hander;
18 COMMIT TRAN;
19 RETURN 0;
20 ERROR_Hander:
21 ROLLBACK TRAN;
22 RETURN @ERRORSUM;
23 END
