您好格式化问题。我有一个填充表。该表是基于行的。但是我需要将表输出作为列。我想我需要一个支点？
我有这张桌子
CREATE TABLE [dbo].[phasepivot](
[pinterval] [varchar](10) NULL,
[phasetype] [smallint] NULL,
[abegdate] [date] NULL,
[abegdatehr] [smallint] NULL,
[penddate] [date] NULL,
[pendhour] [smallint] NULL,
[alength] [int] NULL,
[avglength] [money] NULL,
[achgprevhilo] [money] NULL,
[avgchgprev] [money] NULL,
[achgprevhilopct] [money] NULL,
[avgchgprevpct] [money] NULL,
[adatehilo] [date] NULL,
[ahilovalue] [money] NULL,
[philovalue] [money] NULL,
[aperiodstohilo] [int] NULL,
[avgperiodstohilo] [money] NULL,
[anumhilos] [int] NULL,
[pnumhilos] [money] NULL,
[projphaselen] [varchar](50) NULL,
[recperiodstohilo] [int] NULL,
[recchgprevhilo] [money] NULL,
[recchgprevhilopct] [money] NULL,
[reclength] [money] NULL,
[avalue] [money] NULL,
[LTL] [money] NULL,
[UTL] [money] NULL,
[nxtphstype] [smallint] NULL,
[nxtphsdate] [date] NULL,
[nxtphshour] [smallint] NULL,
[nxtphshilo] [money] NULL
) ON [PRIMARY]
It contains this data

I want the above table contents to look like this:

我使用Pivot吗？如果是，语法是什么？
谢谢！
答案 0 :(得分：1)
要实现此目的，首先需要UNPIVOT你的桌子，然后再PIVOT。使用不同数据类型对列进行拆分时，其中一个复杂因素是必须将它们全部转换为相同的数据类型，并且最有可能转换其中一些（例如日期，百分比等）。在下面的示例中，VARCHAR(32)用作公共数据类型。您可能希望根据需要进行调整。
这是一个仅包含部分列的工作查询：
WITH unpivot_phase AS
(
SELECT property, pinterval, value
FROM
(
SELECT pinterval,
CAST(phasetype AS VARCHAR(32)) phasetype,
CAST(abegdate AS VARCHAR(32)) abegdate,
CAST(abegdatehr AS VARCHAR(32)) abegdatehr,
CAST(penddate AS VARCHAR(32)) penddate,
CAST(pendhour AS VARCHAR(32)) pendhour,
CAST(alength AS VARCHAR(32)) alength,
CAST(avglength AS VARCHAR(32)) avglength,
CAST(achgprevhilo AS VARCHAR(32)) achgprevhilo,
CAST(avgchgprev AS VARCHAR(32)) avgchgprev,
CAST(achgprevhilopct AS VARCHAR(32)) achgprevhilopct,
CAST(avgchgprevpct AS VARCHAR(32)) avgchgprevpct,
CAST(adatehilo AS VARCHAR(32)) adatehilo
-- add rest of the columns here
FROM phasepivot
) s
UNPIVOT
(
value FOR property IN (phasetype, abegdate, abegdatehr,
penddate, pendhour, alength, avglength,
achgprevhilo, avgchgprev, achgprevhilopct,
avgchgprevpct, adatehilo) -- add rest of the columns here
) u
)
SELECT property, H, D, W, M
FROM
(
SELECT property, pinterval, value
FROM unpivot_phase
) s
PIVOT
(
MAX(value) FOR pinterval IN (H, D, W, M)
) p
ORDER BY
CASE property
WHEN 'phasetype' THEN 1
WHEN 'abegdate' THEN 2
WHEN 'abegdatehr' THEN 3
WHEN 'penddate' THEN 4
WHEN 'pendhour' THEN 5
WHEN 'alength' THEN 6
WHEN 'avglength' THEN 7
WHEN 'achgprevhilo' THEN 8
WHEN 'avgchgprev' THEN 9
WHEN 'achgprevhilopct' THEN 10
WHEN 'avgchgprevpct' THEN 11
WHEN 'adatehilo' THEN 12
END
输出：
| PROPERTY | H | D | W | M | |-----------------|------------|------------|------------|------------| | phasetype | 1 | 1 | 2 | 2 | | abegdate | 2013-09-26 | 2013-09-25 | 2013-09-09 | 2012-01-03 | | abegdatehr | 3 | 0 | 0 | 0 | | penddate | 2013-09-27 | 2013-10-01 | 2013-11-18 | 2013-02-04 | | pendhour | 1 | 0 | 0 | 0 | | alength | 12 | 3 | 3 | 21 | | avglength | 6.00 | 5.00 | 11.00 | 14.00 | | achgprevhilo | -16.74 | -37.98 | 97.18 | 501.71 | | avgchgprev | -20.98 | -55.49 | 129.06 | 330.90 | | achgprevhilopct | -0.98 | -2.19 | 5.96 | 41.92 | | avgchgprevpct | -1.53 | -4.42 | 11.60 | 34.09 | | adatehilo | 2013-09-27 | 2013-09-25 | 2013-09-16 | 2013-07-01 |
