CREATE TYPE A_GABProductInfo AS TABLE

(     ProductGroupCode VARCHAR(50),     ProductName VARCHAR(100)

)

存储过程中使用表变量

ALTER  PROCEDURE [dbo].[up_GAB_InsertProductInfo]    

@tempTable A_GABProductInfo READONLY --表值参数

AS    

BEGIN     

        INSERT  INTO A_GABProductInfo     

        SELECT  a.ProductGroupCode,    a.ProductName    FROM    @tempTable a                        

        LEFT JOIN dbo.A_GABProductInfo b ON  a.ProductGroupCode=b.ProductGroupCode                        

                                                           AND a.ProductName=b.ProductName                

        WHERE   b.ProductName IS NULL
