mysql 的行轉列 PIVOT 的使用

語句：SELECT DataDate ,
PropertyText ,
DataValue
FROM RPT_ReportProperty p WITH ( NOLOCK ) JOIN RPT_ReportData d WITH ( NOLOCK ) ON p.PropertyID = d.PropertyID
WHERE d.ReportID = '3'
AND DataDate >= '06 25 2018 12:00AM'
AND DataDate < '07 16 2018 12:00AM'
AND DataParam = '日本'

結果：

語句：

SELECT [月份],[日期],[入庫單量],[入庫及時率],[延誤入庫單量],[異常入庫單量]
FROM ( SELECT DataDate ,
PropertyText ,
DataValue
FROM RPT_ReportProperty p WITH ( NOLOCK ) JOIN RPT_ReportData d WITH ( NOLOCK ) ON p.PropertyID = d.PropertyID
WHERE d.ReportID = '3'
AND DataDate >= '06 25 2018 12:00AM'
AND DataDate < '07 16 2018 12:00AM'
AND DataParam = '日本'
) tb PIVOT ( MAX(DataValue) FOR PropertyText IN ( [月份],[日期],[入庫單量],[入庫及時率],[延誤入庫單量],[異常入庫單量] ) ) a;

結果：
