exec datecut starttime，endtime，@qstarttime，@qendtime，dn as 天数
from work
--哪有这个用法？
你datecut过程丢出来

------解决方案--------------------
不能由
select exec procedure from...
来获得数据.
必须建一个临时表或表变量,用这样的方法从存储过程获得记录集:
insert into @t
exec procedure .....

------解决方案--------------------
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
