我有一个看起来像这样的表：

Associate Pay_Code Hours    Site    Date       Week     Year

Frank   VACP 8.0    Iraq    3/7/2014    10      2014

这个查询：

SELECT Pay_Code, Site, SUM(Hours), Week(Date,4), YEAR(Date)

FROM table

GROUP BY Pay_Code, Site, YEAR(Date), WEEK(Date,4)

给我：

Pay Code    Site    Sum of Hours     Week     Year
OT          Africa   8.0             10      2014

VACP        Iraq     16.0             10      2014 
VTO         US       6.0             10      2014

我想做的是对 Pay_Code 组进行分组，以便进一步总结它们。看起来像这样的东西：

Pay Code2           Pay Code    Site    Sum of Hours      Week     Year
OT                  OT          Africa   8.0              10      2014
                                Jamaica  5.0              10      2014
Paid Shrink         PERS        Canada   2.0              10      2014
                                Iraq     16.0             10      2014
                                US       2.0              10      2014
                    VACP        Iraq     16.0              10      2014
REG                 REG         Africa   40.0              10      2014
                                Canada   38.0              10      2014
                                England  40.0              10      2014
                                Iraq     8.0              10      2014
                                Jamaica  40.0              10      2014
                                US       32.0              10      2014
Unpaid Shrink       VTO             US       6.0             10      2014

目标是按站点、按周报告 Pay_Code2 字段，但表中不存在 Pay_Code2 字段。现在我查询大量数据并使用数据透视表对行进行分组。如果可能的话，我想在 MySQL 中执行此操作。

听起来您正在尝试根据 PayCode 值创建一个新类别。你可以尝试这样的事情：

SELECT CASE
         WHEN Pay_Code = 'OT' THEN 'OT'
         WHEN Pay_Code IN ('VACP','PERS') THEN 'Paid Shrink'
         WHEN Pay_Code = 'REG' THEN 'REG'
         WHEN Pay_Code IN ('VTO','LOA','BER') THEN 'Unpaid Shrink'
         ELSE 'Unknown'
       END as PayCode_2
       ,YEAR(Date), WEEK(Date,4), SUM(Hours), Site, Pay_Code
FROM table
GROUP BY PayCode_2, Pay_Code, Site, YEAR(Date), WEEK(Date,4)
