Sql server 如何在存储过程中合并值？

我有一张这样的桌子：

Entry ID    |     Name    |     qty
12          |  Global     |    5
12          |  In Europe  |    15
12          |  In Asia    |    21
12          |  In US      |    53
18          |  Max        |    5
18          |  In Europe  |    35
18          |  In Asia    |    63
18          |  In US      |    85

我想创建一个存储过程，在其中放置一个参数“Entry ID”，exec give number@ent=12给出：

Entry ID    |  In Europe | In Asia  |  In US | Global
12          |    15      |  21      |    53  |   5

你能帮我一下吗？

试试这个-

查询：

DECLARE @temp TABLE
(
      EntryID INT
    , Name NVARCHAR(50)
    , Qty INT
)

INSERT INTO @temp (EntryID, Name, qty)
VALUES 
    (12, 'Global'     , 5),
    (12, 'In Europe'  , 15),
    (12, 'In Asia'    , 21),
    (12, 'In US'      , 53),
    (18, 'Max'        , 5),
    (18, 'In Europe'  , 35),
    (18, 'In Asia'    , 63),
    (18, 'In US'      , 85)

SELECT 
      EntryID
    , [In Europe] = SUM(CASE WHEN Name = 'In Europe' THEN Qty ELSE 0 END)
    , [In Asia] =   SUM(CASE WHEN Name = 'In Asia' THEN Qty ELSE 0 END)
    , [In US] =     SUM(CASE WHEN Name = 'In US' THEN Qty ELSE 0 END)
    , [Global] =    SUM(CASE WHEN Name = 'Global' THEN Qty ELSE 0 END)
FROM @temp
GROUP BY EntryID

EntryID     In Europe   In Asia     In US       Global
----------- ----------- ----------- ----------- -----------
12          15          21          53          5
18          35          63          85          0

CREATE PROCEDURE dbo.usp_GetEntryID

    @EntryID INT

AS BEGIN

    SET NOCOUNT ON;

    SELECT 
          EntryID
        , [In Europe] = SUM(CASE WHEN Name = 'In Europe' THEN Qty ELSE 0 END)
        , [In Asia] =   SUM(CASE WHEN Name = 'In Asia' THEN Qty ELSE 0 END)
        , [In US] =     SUM(CASE WHEN Name = 'In US' THEN Qty ELSE 0 END)
        , [Global] =    SUM(CASE WHEN Name = 'Global' THEN Qty ELSE 0 END)
    FROM dbo.table1 --<-- your table
    WHERE EntryID = @EntryID
    GROUP BY EntryID

    RETURN 0

END

输出：

DECLARE @temp TABLE
(
      EntryID INT
    , Name NVARCHAR(50)
    , Qty INT
)

INSERT INTO @temp (EntryID, Name, qty)

    (18, 'Max'        , 5),
    (18, 'In Europe'  , 35),
    (18, 'In Asia'    , 63),
    (18, 'In US'      , 85)

    , [In US] =     SUM(CASE WHEN Name = 'In US' THEN Qty ELSE 0 END)

创建过程dbo.usp\u GetEntryID
@EntryID INT
作为开始
不计数；
挑选
入口标识
，[在欧洲]=总和（当名称='在欧洲'，则数量0结束时）
，[在亚洲]=总和（如果名称为“在亚洲”，则数量为0结束）
，[In-US]=总和（如果名称为'In-US'，则数量为0结束）
，[Global]=总和（当名称为'Global'时，则为0结束）
从dbo.table1--尝试以下操作：
这是动态查询，不需要在任何地方提及列名

CREATE PROC sp_Sample
@EntryID int
As
BEGIN
SET NOCOUNT ON
DECLARE @cols varchar(100)
DECLARE @Query varchar(1000)
select @cols = STUFF((SELECT distinct ',' + QUOTENAME(name)

            ).value('.', 'VARCHAR(MAX)') 
        ,1,1,'')
