我想转置下表中的数据:
GUID | ChecklistID | DataCollectionID | data | Created_On
0113 MT-B5-SectionA MT-B5-0001 B101 2018-07-02 15:22:02
0113 MT-B5-SectionA MT-INSPECTION 1 OK 2018-07-02 15:22:02
0113 MT-B5-SectionA MT-B5-0002 B102 2018-07-02 15:22:02
0113 MT-B5-SectionA MT-INSPECTION 2 NG 2018-07-02 15:22:02
0113 MT-B5-SectionA MT-B5-0003 B103 2018-07-02 15:22:02
0113 MT-B5-SectionA MT-INSPECTION 3 OK 2018-07-02 15:22:02
像这样:
Created_On | Roller Code | Inspection
2018-07-02 15:22:02 B101 OK
2018-07-02 15:22:02 B102 NG
2018-07-02 15:22:02 B103 OK
但是使用此查询:
SELECT C.Created_On,
MAX(CASE WHEN c.DataCollectionID like 'MT-B5%' THEN c.data ELSE NULL END) AS 'Roller Code',
MAX(CASE WHEN c.DataCollectionID like 'MT-INSPECTION%' THEN c.data ELSE NULL END) AS 'Inspection',
FROM checklist_detail c
WHERE ChecklistID = 'MT-B5-SectionA' and Created_On like '2018-07-02%'
我只得到最后一行
Created_On | Roller Code | Inspection
2018-07-02 15:22:02 B103 OK
DataCollectionID或多或少是动态的。可以得到我想要的输出吗?
