获取存储过程output参数 急 ~

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本文来自CSDN博客，转载请标明出处：http://blog.csdn.net/fredrickhu/archive/2009/09/23/4584118.aspx

SQL code
D. 使用 OUTPUT 参数OUTPUT 参数允许外部过程、批处理或多条 Transact-SQL 语句访问在过程执行期间设置的某个值。下面的示例创建一个存储过程 (titles_sum)，并使用一个可选的输入参数和一个输出参数。首先，创建过程：USE pubsGOIF EXISTS(SELECT name FROM sysobjects      WHERE name = 'titles_sum' AND type = 'P')   DROP PROCEDURE titles_sumGOUSE pubsGOCREATE PROCEDURE titles_sum @@TITLE varchar(40) = '%', @@SUM money OUTPUTASSELECT 'Title Name' = titleFROM titles WHERE title LIKE @@TITLE SELECT @@SUM = SUM(price)FROM titlesWHERE title LIKE @@TITLEGO接下来，将该 OUTPUT 参数用于控制流语言。 说明  OUTPUT 变量必须在创建表和使用该变量时都进行定义。参数名和变量名不一定要匹配，不过数据类型和参数位置必须匹配（除非使用 @@SUM = variable 形式）。 DECLARE @@TOTALCOST moneyEXECUTE titles_sum 'The%', @@TOTALCOST OUTPUTIF @@TOTALCOST < 200 BEGIN   PRINT ' '   PRINT 'All of these titles can be purchased for less than $200.'ENDELSE   SELECT 'The total cost of these titles is $'          + RTRIM(CAST(@@TOTALCOST AS varchar(20)))下面是结果集：Title Name                                                               ------------------------------------ The Busy Executive's Database GuideThe Gourmet MicrowaveThe Psychology of Computer Cooking(3 row(s) affected)Warning, null value eliminated from aggregate.
