Question

我正在尝试运行此代码

INSERT INTO payroll_ho.tb_quotapos(QPCompany,QPQRndYear,QPQRndMonth,QPLine,QPPart,QPDep,QPBand,QPSubBand,QPPos,QPExist1,QPExist2,QPExist3)
SELECT "G02",2016,6,mp.PerWorkLine,mp.PerPart,mp.PerDep,PerBand,PerSubBand,mp.PerPos,c1,c2,c3 FROM ms_per mp
 LEFT JOIN payroll_ho.tb_subbandpos ON BPBand=mp.PerSubBand
 LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c1 FROM ms_per WHERE PerQuota=1 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp1 ON mp.PerWorkLine=mp1.PerWorkLine AND mp.PerPart=mp1.PerPart AND mp.perdep=mp1.perdep AND mp.perpos=mp1.perpos
 LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c2 FROM ms_per WHERE PerQuota=2 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp2 ON mp.PerWorkLine=mp2.PerWorkLine AND mp.PerPart=mp2.PerPart AND mp.perdep=mp2.perdep AND mp.perpos=mp2.perpos
 LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c3 FROM ms_per WHERE PerQuota=3 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp3 ON mp.PerWorkLine=mp3.PerWorkLine AND mp.PerPart=mp3.PerPart AND mp.perdep=mp3.perdep AND mp.perpos=mp3.perpos
 WHERE mp.PerEmploying="Y"
  AND (c1>0 OR c2>0 OR c3>0)
 GROUP BY mp.PerWorkLine,mp.PerPart,mp.PerDep,PerBand,PerSubBand,mp.PerPos
ON DUPLICATE KEY UPDATE QPExist1=c1, QPExist2=c2, QPExist3=c3

MySQL返回错误Unknown column 'c1' in 'field list' 为什么MySQL在c1子句中没有看到SELECT？

编辑：我认为问题出在ON DUPLICATE子句中。 SELECT工作正常。

EDIT2 ：以下是每个表的定义。

Answer 1

尝试以下操作（注意，我仍在编辑它以重新获取数据库名称，我认为表名前面有2个点）。

但是通过涉及派生表来清理列名已经成功了。派生表具有将值折叠到包装它的查询中的奇妙副作用。在这种情况下，它会在INSERT ON DUPLICATE UPDATE上删除group by禁止使用。

INSERT INTO tb_quotapos(QPCompany,QPQRndYear,QPQRndMonth,QPLine,QPPart,QPDep,QPBand,QPSubBand,QPPos,QPExist1,QPExist2,QPExist3)
select col1,col2,col3,col4,col5,col6,col7,col8,col9,col10,col11,col12
from
(   SELECT "G02" as col1,2016 as col2,6 as col3,
    mp.PerWorkLine as col4,mp.PerPart as col5,mp.PerDep as col6,
    PerBand as col7,PerSubBand as col8,mp.PerPos as col9,
    c1 as col10,c2 as col11,c3 as col12 
    FROM ms_per mp
    LEFT JOIN tb_subbandpos ON BPBand=mp.PerSubBand
    LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c1 FROM ms_per WHERE PerQuota=1 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp1 ON mp.PerWorkLine=mp1.PerWorkLine AND mp.PerPart=mp1.PerPart AND mp.perdep=mp1.perdep AND mp.perpos=mp1.perpos
    LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c2 FROM ms_per WHERE PerQuota=2 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp2 ON mp.PerWorkLine=mp2.PerWorkLine AND mp.PerPart=mp2.PerPart AND mp.perdep=mp2.perdep AND mp.perpos=mp2.perpos
    LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c3 FROM ms_per WHERE PerQuota=3 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp3 ON mp.PerWorkLine=mp3.PerWorkLine AND mp.PerPart=mp3.PerPart AND mp.perdep=mp3.perdep AND mp.perpos=mp3.perpos
    WHERE mp.PerEmploying="Y"
    AND (c1>0 OR c2>0 OR c3>0)
    GROUP BY mp.PerWorkLine,mp.PerPart,mp.PerDep,PerBand,PerSubBand,mp.PerPos
) xDerived
ON DUPLICATE KEY UPDATE QPExist1=col10, QPExist2=col11, QPExist3=col12;

版本2（包含两个似乎需要payroll_ho.的地方）：

INSERT INTO payroll_ho.tb_quotapos(QPCompany,QPQRndYear,QPQRndMonth,QPLine,QPPart,QPDep,QPBand,QPSubBand,QPPos,QPExist1,QPExist2,QPExist3)
select col1,col2,col3,col4,col5,col6,col7,col8,col9,col10,col11,col12
from
(   SELECT "G02" as col1,2016 as col2,6 as col3,
    mp.PerWorkLine as col4,mp.PerPart as col5,mp.PerDep as col6,
    PerBand as col7,PerSubBand as col8,mp.PerPos as col9,
    c1 as col10,c2 as col11,c3 as col12 
    FROM ms_per mp
    LEFT JOIN payroll_ho.tb_subbandpos ON BPBand=mp.PerSubBand
    LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c1 FROM ms_per WHERE PerQuota=1 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp1 ON mp.PerWorkLine=mp1.PerWorkLine AND mp.PerPart=mp1.PerPart AND mp.perdep=mp1.perdep AND mp.perpos=mp1.perpos
    LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c2 FROM ms_per WHERE PerQuota=2 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp2 ON mp.PerWorkLine=mp2.PerWorkLine AND mp.PerPart=mp2.PerPart AND mp.perdep=mp2.perdep AND mp.perpos=mp2.perpos
    LEFT JOIN (SELECT PerWorkLine,PerPart,PerDep,PerPos,count(*) c3 FROM ms_per WHERE PerQuota=3 AND PerEmploying="Y" AND PerISO="Y"  AND PerCGroup = "01"  GROUP BY PerWorkLine,PerPart,PerDep,PerPos) mp3 ON mp.PerWorkLine=mp3.PerWorkLine AND mp.PerPart=mp3.PerPart AND mp.perdep=mp3.perdep AND mp.perpos=mp3.perpos
    WHERE mp.PerEmploying="Y"
    AND (c1>0 OR c2>0 OR c3>0)
    GROUP BY mp.PerWorkLine,mp.PerPart,mp.PerDep,PerBand,PerSubBand,mp.PerPos
) xDerived
ON DUPLICATE KEY UPDATE QPExist1=col10, QPExist2=col11, QPExist3=col12;

由于Group By，派生表是必要的。来自手册页INSERT ... SELECT Syntax：

在ON DUPLICATE KEY UPDATE的值部分，您可以参考其他表中的列，只要你不使用GROUP BY 选择部分。一个副作用是你必须限定nonunique列值部分中的名称。

在答案Justin中归功于here。但我确实提供了上面手册页的更新链接。

这个INSERT INTO SELECT语句有什么问题？
