1、DB02中SQL代码，下面代码是读取直接人工数字最大的工序
SELECT
m.WERKS AS plant,
m.MATNR AS material,
m.PLNNR AS route_no,
a.PLNKN AS operation,
o.VGW01 AS direct_labor
FROM
MAPL m
INNER JOIN PLKO k ON m.PLNNR = k.PLNNR AND m.PLNAL = k.PLNAL
INNER JOIN PLAS a ON k.PLNNR = a.PLNNR AND k.PLNAL = a.PLNAL
INNER JOIN PLPO o ON a.PLNNR = o.PLNNR AND a.PLNKN = o.PLNKN
WHERE
m.MATNR = '8014217002'
AND m.WERKS = '8201'
AND k.PLNTY = 'N'
AND m.LOEKZ = ''
AND k.LOEKZ = ''
AND a.LOEKZ = ''
AND o.LOEKZ = ''
AND o.VGW01 = (
SELECT MAX(o2.VGW01)
FROM MAPL m2
INNER JOIN PLKO k2 ON m2.PLNNR = k2.PLNNR AND m2.PLNAL = k2.PLNAL

ORDER BY
