我的查询存在问题，请查看：http://sqlfiddle.com/#!9/8102d/1

我的预期结果如下：

PartID           |IdMesin|MR|MOSGN|NOP|MT|MS|MOSTRO|NF |MORREST|MOR |NJ|TRY |
AWDX-FG001-HC-KGX|BH 260K|0 |   0 | 0 |0 |0 |0     |600|0      |1200|0 |9000|
AWDX-FG001-HC-KGX|BH 260Q|0 |   0 | 0 |0 |0 |0     |0  |0      |0   |0 |3600|

我希望你能帮我解决，任何帮助都会受到赞赏。

你需要有条件的聚合在SO和其他地方有很多例子，而这是另一个 -

SELECT
    PartID,
    IdMesin,
    SUM(CASE WHEN IdDowntime = 'MR001' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS MR,
    SUM(CASE WHEN IdDowntime = 'MOSGN01' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0, 0)) ELSE 0 END) AS MOSGN,
    SUM(CASE WHEN IdDowntime = 'NO001' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS NOP,
    SUM(CASE WHEN IdDowntime = 'MT001' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS MT,
    SUM(CASE WHEN IdDowntime = 'MOS01' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS MS,
    SUM(CASE WHEN IdDowntime = 'MOSTR01' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0, 0)) ELSE 0 END) AS MOSTRO,
    SUM(CASE WHEN IdDowntime = 'NF001' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS NF,
    SUM(CASE WHEN IdDowntime = 'MOSR01' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,  0)) ELSE 0 END) AS MORREST,
    SUM(CASE WHEN IdDowntime = 'MOR01' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS MOR,
    SUM(CASE WHEN IdDowntime = 'NJ001' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS NJ,
    SUM(CASE WHEN IdDowntime = 'TRY01' THEN TIME_TO_SEC(maketime(durasi + 0,substring_index(durasi, 'Jam ', - 1) + 0,   0)) ELSE 0 END) AS TRY
FROM    trans_lhpdtdw
WHERE DivisiId = 'IJ001' AND Tanggal = '2017-10-02'
GROUP BY    PartID, IdMesin
ORDER BY PartID
