一个有关存储过程里面循环的问题

现在有一个存储过程1（SP1）,如今想建立另外一个存储过程2（SP2），在SP2里面循环调用SP1。
  SP1本身有三个参数@a,@b,@c,先在SP2里面declare一个表table1，表里面有三个字段a,b,c,然后在这table1里面插入数据，将table1里面的数据一行一行地传递到SP1里面去，这里就涉及到循环，直到table1里面的全部数据传递完，SP1每接受table1传来的1行数据就生成一个值d，最后将值存储在另外一个表table1里面。
  自己写了好久，不会写了，思路没了，请教各位大侠了。
  set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON

CREATE PROCEDURE [dbo].[pt_AppTempGetFiliationDisposenew]

AS

declare @sourcetable table
(
instance_id varchar(256),
template_id varchar(256),
version varchar(256),
appd_id int
)

declare @counts table
(
instance_id_counts varchar(256),
counts_counts int

)

insert into @sourcetable(instance_id,template_id,version,appd_id)
select a11.instance_id,b11.template_id,b11.version,c11.appd_id 
from jhoa_approve a11,jhoa_approve_instance b11,(select last11.*,xyz11.appd_id
from jhoa_approve as xyz11,(select instance_id,max(app_id) as last_id from jhoa_approve group by instance_id) as last11 
where xyz11.app_id=last11.last_id ) c11
where a11.instance_id=b11.instance_id and a11.instance_id=c11.instance_id



select count(*) as num11 from @sourcetable
declare @i int
i='1'
while @i<=num11
  begin
  delete from diapose1117
  insert dispose1117 Exec pt_AppTempGetFiliationDispose @apptid=template_id,@version=version,@currentappdid=appd_id
  select count(*) as counts from dispose1117
  insert into @counts values(instance_id,counts)

  end

--查询最后2个字段结果
select * from @counts

太麻烦了吧...
直接建一个临时表让被调用过程访问?

SQL code

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

建临时表比较简单，不过在存储过程中搞循环会耗费很多内存，而且速度超慢。
