如何在动态查询中使用表变量

Question

我想使用表变量而不是临时表,但我的主要查询结构是动态的.动态查询是单引号,所以如何从@TableVariable获取数据.我不想删除动态查询,因为稍后会添加一些参数.

例如,以下是错误代码,我已将表变量写入动态查询........

/*Declare Table Variable*/
DECLARE @TempVehicles TABLE
    (
        [VehicleID] INT
    )   
/*Insert data into Table Variable*/
INSERT INTO @TempVehicles
(
    [VehicleID]
)
SELECT  VehicleID
FROM tbl_Vehicles

/*Dynamic Query and Main SQL Construction*/
DECLARE @SQL NVARCHAR(MAX)
SET @SQL ='SELECT Cust_ID,A.VehicleID,GISInfo 
           FROM @TempVehicles A INNER JOIN tbl_GISData B ON A.VehicleID=B.VehicleID'

EXECUTE SP_EXECUTESQL @SQL

帮助我,在这.

提前致谢.

试试这个 :

CREATE TYPE IntegerTableType AS TABLE (ID INT);
go

DECLARE @TempVehicles IntegerTableType; 

INSERT  @TempVehicles
values (1);





DECLARE @SQL NVARCHAR(MAX);
SET @SQL ='SELECT * 
           FROM @TempVehicles;';


EXECUTE SP_EXECUTESQL @SQL,N'@TempVehicles IntegerTableType READONLY',
@TempVehicles;
