大家帮忙看一下这段SQL文
update MBPAPP_BBS_TAT_WEEKLY_TBL
set DISTRICT = FR_MASTER_TBL.VALUE
where MBPAPP_DFB_THREAD_TBL.TAT <> NULL

LEFT JOIN FR_MASTER_TBL ON
MBPAPP_BBS_TAT_WEEKLY_TBL.DISTRICT = FR_MASTER_TBL.ID
AND FR_MASTER_TBL..DIVISION = '02 '
LEFT JOIN MBPAPP_DFB_THREAD_TBL ON
MBPAPP_BBS_TAT_WEEKLY_TBL.ID = MBPAPP_DFB_THREAD_TBL.DFB_THREAD_ID

-------------
是在LEFT附近出错.不明白

[解决办法]
update MBPAPP_BBS_TAT_WEEKLY_TBL
set DISTRICT = B.VALUE

FROM MBPAPP_BBS_TAT_WEEKLY_TBL a LEFT JOIN
FR_MASTER_TBL B ON A.DISTRICT = B.ID LEFT JOIN
MBPAPP_DFB_THREAD_TBL C ON A.ID = C.DFB_THREAD_ID

where A.TAT <> NULL
AND B.DIVISION = '02 '
[解决办法]
update a
set a.DISTRICT = b.VALUE
from MBPAPP_BBS_TAT_WEEKLY_TBL a
left join FR_MASTER_TBL b on a.DISTRICT = b.ID and b.DIVISION = '02 '
left join MBPAPP_DFB_THREAD_TBL c on a.ID = c.DFB_THREAD_ID
where c.TAT <> null
