使用 SQL 服务器将月份列汇总到财政年度

Question

我想总结一个 table 主要由一系列月份组成的。每个月的列都有一个 header，格式为 MMMYY。我需要按财政年度动态总结这个 table。我们的财政年度从 11 月开始，因此输入输出如下：

输入：

输出：

有人对我如何使用 SQL 服务器进行此操作有任何建议吗？我考虑过根据每月财政年度休息时间 (NovYY) 对包含所有给定月份和年份的临时 table 进行分区，但我还没有弄清楚如何根据 LIKE关键词搜索。底线 - 我完全不知道如何在不对日期进行硬编码的情况下有效地执行此操作。

假设上面的示例输入是 dbo.USA_Historic_Txg_Revenue。到目前为止我有以下内容：

select * into #temp from dbo.USA_Historic_Txg_Revenue

with MMMYY as
(
    select Name
    from tempdb.sys.columns 
    where object_id = OBJECT_ID('tempdb..#temp')
    and isnumeric(right(name, 2)) = 1
)
select * from MMMYY

我认为您正在寻找这样的东西：

--CREATE TABLE #table (Name NVARCHAR(100), Oct12 INT, Nov12 INT, Dec12 INT, Jan13 INT, Feb13 INT, Mar13 INT, Apr13 INT, May13 INT, Jun13 INT, Jul13 INT, Aug13 INT, Sep13 INT, Oct13 INT, Nov13 INT, Dec13 INT, Jan14 INT, Feb14 INT, Mar14 INT)
--INSERT #table VALUES ('Record1',5,3,2,0,1,5,4,3,6,5,4,2,1,0,1,1,1,2)
--, ('Record2',4,1,3,2,1,3,3,1,4,4,3,2,1,0,2,2,2,2);

DECLARE @monthlist NVARCHAR(MAX)
SELECT @monthlist = ISNULL(@monthlist + ',', '') + Name -- select top 100 *
FROM tempdb.sys.columns
WHERE [object_id] = OBJECT_ID('tempdb..#table')
AND Name <> 'Name';

DECLARE @SQL NVARCHAR(MAX) = 
'SELECT DISTINCT Name
    , SUM(Val) OVER (PARTITION BY Name, CASE WHEN Mth LIKE ''Nov%'' OR Mth LIKE ''Dec%'' THEN RIGHT(Mth, 2) ELSE RIGHT(Mth, 2) - 1 END) InsertColName
    , CASE WHEN Mth LIKE ''Nov%'' OR Mth LIKE ''Dec%'' THEN ''Nov'' + RIGHT(Mth, 2) ELSE ''Nov'' + CONVERT(NVARCHAR, RIGHT(Mth, 2) - 1) END FiscalStart
FROM #table
UNPIVOT (Val FOR Mth IN (' + @monthlist + ')) a
ORDER BY Name, CASE WHEN Mth LIKE ''Nov%'' OR Mth LIKE ''Dec%'' THEN ''Nov'' + RIGHT(Mth, 2) ELSE ''Nov'' + CONVERT(NVARCHAR, RIGHT(Mth, 2) - 1) END'
EXEC(@SQL)

对于您的特定查询，您可以直接从 table 派生 monthlist 而无需临时 table...

例如

DECLARE @monthlist NVARCHAR(MAX)
SELECT @monthlist = ISNULL(@monthlist + ',', '') + COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'USA_Historic_Txg_Revenue'
AND COLUMN_NAME <> 'Name';

DECLARE @SQL NVARCHAR(MAX) = 
'SELECT DISTINCT Name
    , SUM(Val) OVER (PARTITION BY Name, CASE WHEN Mth LIKE ''Nov%'' OR Mth LIKE ''Dec%'' THEN RIGHT(Mth, 2) ELSE RIGHT(Mth, 2) - 1 END) InsertColName
    , CASE WHEN Mth LIKE ''Nov%'' OR Mth LIKE ''Dec%'' THEN ''Nov'' + RIGHT(Mth, 2) ELSE ''Nov'' + CONVERT(NVARCHAR, RIGHT(Mth, 2) - 1) END FiscalStart
FROM dbo.USA_Historic_Txg_Revenue
UNPIVOT (Val FOR Mth IN (' + @monthlist + ')) a
ORDER BY Name, CASE WHEN Mth LIKE ''Nov%'' OR Mth LIKE ''Dec%'' THEN ''Nov'' + RIGHT(Mth, 2) ELSE ''Nov'' + CONVERT(NVARCHAR, RIGHT(Mth, 2) - 1) END'
EXEC(@SQL)
