Question

我有存储过程A和B从不同的表中获取结果。这两个程序都有以下结果：

的ItemID
价格
数量
SUM
出版商

是否可以同时存储两个存储过程，然后按作者分组？关于我如何解决这个问题的任何指南或提示？

DECLARE @OverallResults AS TABLE
(
  identifiers INT NOT NULL IDENTITY(1, 1), 
    sales_price INT, 
    quantity INT,
    PUBLISHER VARCHAR
)

INSERT INTO @OverallResults (identifiers, sales_price, quantity,PUBLISHER)
EXEC reportItunes

INSERT INTO @OverallResults (identifiers, sales_price, quantity,PUBLISHER)
EXEC reportDDS

SELECT A.Publisher, 
       SUM([sales_price]) AS [TotalPrice], 
       SUM([Quantity] AS [TotalQuantity], 
FROM @OverallResults A
GROUP BY A.Publisher

是的，您可以使用该结构创建表变量，并将两个SP的结果集插入表变量中：

DECLARE @OverallResults AS TABLE
(
  Id INT NOT NULL IDENTITY(1, 1),
  ... Your other columns
)

INSERT INTO @OverallResults ([ItemID], [Price], [Quantity], [SUM], [Publisher])
EXEC StoredProcedure1

INSERT INTO @OverallResults ([ItemID], [Price], [Quantity], [SUM], [Publisher])
EXEC StoredProcedure2

SELECT A.Publisher, 
       SUM([Price]) AS [TotalPrice], 
       SUM([Quantity] AS [TotalQuantity], 
       SUM([Sum]) AS [TotalSum]
FROM @OverallResults A
GROUP BY A.Publisher

DECLARE @OverallResults AS TABLE
(
    identifiers INT NOT NULL IDENTITY(1, 1), 
    sales_price INT, 
    quantity INT,
    PUBLISHER VARCHAR(128)
)

INSERT INTO @OverallResults (sales_price, quantity,PUBLISHER)
EXEC reportItunes

INSERT INTO @OverallResults (sales_price, quantity,PUBLISHER)
EXEC reportDDS

SELECT A.Publisher, 
       SUM([sales_price]) AS [TotalPrice], 
       SUM([Quantity] AS [TotalQuantity] 
FROM @OverallResults A
GROUP BY A.Publisher

然后您可以使用表变量进行聚合。

您的脚本已更正

从插入列表
为发布者列指定了非默认长度
删除了上次选择中的额外逗号

将两个存储过程和发布者分组
