Question

我有一个存储过程，如：

create procedure [dbo].[Mark]
   SELECT 
       NAME, TOT1, TOT2, TOT3, (TOT1+TOT2+TOT3)/3 AS Average
   FROM
       (SELECT  
            NAME, 
            ISNULL([1],0) AS TOT1,
            ISNULL([2],0) AS TOT2,
            ISNULL([3],0) AS TOT3
       FROM 
           (SELECT  
                ROW_NUMBER() OVER (PARTITION BY NAME ORDER BY NAME) RN,
                NAME,
                TOT
            FROM    
                T) S
 PIVOT (MAX(TOT) FOR RN IN ([1],[2],[3])) AS PVT
 ) T

此存储过程的输出为：

name   Tot1  Tot2  Tot3    Avg
-------------------------------
 a      50     30    45     42
 b      30     0      0     10

从这个存储过程中，我想创建另一个存储过程来记录20-50之间的平均值。如何获得？我尝试使用临时表。但我无法访问临时表到另一个存储过程

我的输出必须是

name   Tot1  Tot2  Tot3    Avg
---------------------------------
 a      50     30    45    42

Answer 1

DECLARE @MyTableVar TABLE(
    name VARCHAR(20),
    Tot1 [decimal](15, 6),
    Tot2 [decimal](15, 6),
    Tot3 [decimal](15, 6),
    Avg [decimal](15, 6))

INSERT INTO @MyTableVar EXECUTE sp_executesql [Mark]

SELECT * FROM @MyTableVar WHERE Avg BETWEEN 20 AND 50

只需将临时表@MyTableVar替换为您需要的数据类型即可。我还没有对此进行测试，但我非常确定sp_executesql正是您所寻找的。

修改为您更新数据类型。

只需更新您的程序以接受可选参数：

ALTER PROCEDURE Mark 
    -- Add the parameters for the stored procedure here
     @RANGE_START INT = NULL, @RANGE_END INT = NULL
AS
BEGIN

    SELECT *
    FROM (
    SELECT 
           NAME, TOT1, TOT2, TOT3, (TOT1+TOT2+TOT3)/3 AS Average
       FROM
          (SELECT  
                NAME, 
                ISNULL([1],0) AS TOT1,
                ISNULL([2],0) AS TOT2,
                ISNULL([3],0) AS TOT3
           FROM 
               (SELECT  
                    ROW_NUMBER() OVER (PARTITION BY NAME ORDER BY NAME) RN,
                    NAME,
                    TOT
                FROM    
                    T) S
     PIVOT (MAX(TOT) FOR RN IN ([1],[2],[3])) AS PVT
     ) T
     ) R
     WHERE (@RANGE_START IS NULL OR R.Average >= @RANGE_START) 
       AND( @RANGE_END IS NULL OR R.Average <=  @RANGE_END)

END
GO

用法（新参数）：

EXEC dbo.Mark 20, 41

<强>结果：

   NAME    TOT1    TOT2    TOT3    Average
    a       50      30      45        41

用法（与之前相同）：

EXEC dbo.Mark

<强>结果：

NAME    TOT1    TOT2    TOT3    Average
a       50      30      45        41
b       30      0       0         10

如果你真的想创建一个新程序并使用Temp表，那么：

更新初始值

ALTER PROCEDURE Mark 
    -- Add the parameters for the stored procedure here
AS
BEGIN
    SELECT 
           NAME, TOT1, TOT2, TOT3, (TOT1+TOT2+TOT3)/3 AS Average INTO ##TEMP
       FROM
          (SELECT  
                NAME, 
                ISNULL([1],0) AS TOT1,
                ISNULL([2],0) AS TOT2,
                ISNULL([3],0) AS TOT3
           FROM 
               (SELECT  
                    ROW_NUMBER() OVER (PARTITION BY NAME ORDER BY NAME) RN,
                    NAME,
                    TOT
                FROM    
                    T) S
     PIVOT (MAX(TOT) FOR RN IN ([1],[2],[3])) AS PVT
     ) T

     SELECT * FROM ##TEMP

END
GO

创建新的

CREATE PROCEDURE Mark2
    @RANGE_START INT = NULL, @RANGE_END INT = NULL
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    EXEC dbo.Mark

    SELECT * FROM ##TEMP
    WHERE Average BETWEEN @RANGE_START AND @RANGE_END

   DROP TABLE ##TEMP
END
GO

<强>用法：

EXEC Mark2 20, 50

最简单的处理方法是不使用存储过程。如果您改为创建表值函数，则可以轻松地针对它编写其他查询/存储过程。

从另一个存储过程
