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) exec GetUserName select #tempTable --用完之后要把临时表清空 drop table #tempTable--需要注意的是,这种方法不能嵌套。例如: procedure a begin ... insert #table exec b end procedure b begin ... insert #table exec c select * from #table end procedure c begin ... select * from sometable end --这里a调b的结果集,而b中也有这样的应用b调了c的结果集,这是不允许的, --会报“INSERT EXEC 语句不能嵌套”错误。在实际应用中要避免这类应用的发生。 第三种方法:声明一个变量,用exec(@sql)执行: 1);EXEC 执行SQL语句 declare @rsql varchar(250) declare @csql varchar(300) declare @rc nvarchar(500) declare @cstucount int declare @ccount int set @rsql='(select Classroom_id from EA_RoomTime where zc='+@zc+' and xq='+@xq+' and T'+@time+'=''否'') and ClassroomType=''1''' --exec(@rsql) set @csql='select @a=sum(teststucount),@b=sum(classcount) from EA_ClassRoom where classroom_id in ' set @rc=@csql+@rsql exec sp_executesql @rc,N'@a int output,@b int output',@cstucount output,@ccount output--将exec的结果放入变量中的做法 --select @csql+@rsql --select @cstucount 给以一点参考资料,结合着自己写写
------解决方案--------------------
create table #temp{'字段名'} declare @sql nvarchar(8000) set @sql='insert into #temp exec 存储过程1 ' exec (@sql) declare @cur currsor ----然后去循环#temp ,利用游标去执行存储过程。 --
