存储过程调用存储过程结果有关问题

第一种方法: 使用output参数USE AdventureWorks;GOIF OBJECT_ID ( 'Production.usp_GetList', 'P' ) IS NOT NULL     DROP PROCEDURE Production.usp_GetList;GOCREATE PROCEDURE Production.usp_GetList @product varchar(40)     , @maxprice money     , @compareprice money OUTPUT    , @listprice money OUTAS    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 TestasDECLARE @compareprice money, @cost money EXECUTE Production.usp_GetList '%Bikes%', 700,     @compareprice OUT,     @cost OUTPUTIF @cost <= @compareprice BEGIN    PRINT 'These products can be purchased for less than     $'+RTRIM(CAST(@compareprice AS varchar(20)))+'.'ENDELSE    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 GetUserNameasbegin    select 'UserName'endCreate table #tempTable (userName nvarchar(50))insert into #tempTable(userName)exec GetUserNameselect #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 [email protected]+' and [email protected]+' and [email protected]+'=''否'') and ClassroomType=''1'''        --exec(@rsql)        set @csql='select @a=sum(teststucount),@b=sum(classcount) from EA_ClassRoom where classroom_id in '        set @[email protected][email protected]        exec sp_executesql @rc,[email protected] int output,@b int output',@cstucount output,@ccount output--将exec的结果放入变量中的做法        --select @[email protected]        --select @cstucount给以一点参考资料，结合着自己写写
------解决方案--------------------
SQL code
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。--
