SQL一个存储过程调用另一个存储过程 获得返回值问题
第一种方法: 使用output参数
USE AdventureWorks;
GO
IF OBJECT_ID ( 'Production.usp_GetList', 'P' ) IS NOT NULL
DROP PROCEDURE Production.usp_GetList;
GO
CREATE PROCEDURE Production.usp_GetList @product varchar(40)
, @maxprice money
, @compareprice money OUTPUT
, @listprice money OUT
AS
SELECT p.name AS Product, p.ListPrice AS 'List Price'
from Production.Product p
JOIN Production.ProductSubcategory s
ON p.ProductSubcategoryID = s.ProductSubcategoryID
WHERE s.name LIKE @product AND p.ListPrice < @maxprice;
-- Populate the output variable @listprice.
SET @listprice = (SELECT MAX(p.ListPrice)
from Production.Product p
JOIN Production.ProductSubcategory s
ON p.ProductSubcategoryID = s.ProductSubcategoryID
WHERE s.name LIKE @product AND p.ListPrice < @maxprice);
-- Populate the output variable @compareprice.
SET @compareprice = @maxprice;
GO
另一个存储过程调用的时候:
Create Proc Test
as
DECLARE @compareprice money, @cost money
EXECUTE Production.usp_GetList '%Bikes%', 700,
@compareprice OUT,
@cost OUTPUT
IF @cost <= @compareprice
BEGIN
PRINT 'These products can be purchased for less than
$'+RTRIM(CAST(@compareprice AS varchar(20)))+'.'
END
ELSE
PRINT 'The prices for all products in this category exceed
$'+ RTRIM(CAST(@compareprice AS varchar(20)))+'.'
第二种方法:创建一个临时表
create proc GetUserName
as
begin
select 'UserName'
end
Create table #tempTable (userName nvarchar(50))
insert into #tempTable(userName)
