Question

首先，我的表结构类似于：

CREATE TABLE Testing(
       [ID]        NVARCHAR(50),
       [DATE]      DATETIME,
       [TOTAL]     INT,
       [ITEM]      NVARCHAR(50),
       [Warehouse] NVARCHAR(50)
)ON[PRIMARY]

我在这里放了一些样本：

[ID] [Date]      [Total] [Item] [Warehouse]
1    2011-04-04  400     A0001   B12
2    2011-05-04  500     A0001   B13
3    2011-04-30  400     A0001   B12
4    2011-04-25  400     A0001   B13
5    2011-06-05  600     A0001   B12
6    2011-03-02  300     A0001   B11
7    2011-05-28  500     A0001   B13

我也想按月分组[项目]和[仓库]以及[日期] 例如输出：

结果应该是这样的

[Date]        [Total]   [Item]  [Warehouse]
March 2011     300       A0001   B11
April 2011     800       A0001   B12
June 2011      500       A0001   B12
April 2011     400       A0001   B13
May 2011       1000      A0001   B13

我尝试了类似的sql，我在月份和年份解析部分进行选择

SELECT [Item],[Warehouse],SUM(Total) AS Total
FROM [Testing]
WHERE Datepart(month,[Date]) = 4 AND DATEPART(year,[Date]) = 2011
GROUP BY [Item],[Warehouse]

我得到了预期的结果？有什么办法吗？我真的试图通过不同的仓库和物品来实现每个月和每年的紧密平衡？

听起来我需要循环前缀表.. 无论如何要这样做？

Answer 1

查看以下功能

DATENAME (Transact-SQL)和DATEPART

看一下下面的例子

DECLARE @Table TABLE(
        DateValue DATETIME
)

INSERT INTO @Table SELECT '01 Jan 2011'
INSERT INTO @Table SELECT '01 Feb 2011'
INSERT INTO @Table SELECT '01 Feb 2011'

SELECT  DATENAME(month,DateValue) + ' ' + CAST(DATEPART(year,DateValue) AS VARCHAR(4)),
        COUNT(1) TotalCnt
FROM    @Table
GROUP BY DATENAME(month,DateValue) + ' ' + CAST(DATEPART(year,DateValue) AS VARCHAR(4))

结果：

February 2011   2
January 2011    1

Answer 2

我认为SQL Server端的格式化日期（通常）是一个想法，但无论如何你可以尝试：

select datename(mm, dateadd(m, datediff(m, 0, [date]), 0)) + ' ' +
      select cast(datepart(yy, dateadd(m, datediff(m, 0, [date]), 0)) as varchar)
      [date] sum(total) as total, item,warehouse
from testing
group by item, warehouse, dateadd(m, datediff(m, 0, [date]), 0)

Sql Server：按月，按年计算数据
