我正在使用以下查询缩写子查询，但我收到错误

无效的sql语句错误

我不知道这里有什么问题

select enq.followup_sr_no ColFolSrno,case when enq.followup_sr_no=(select max(followup_sr_no) from  xxcus.XXACL_PN_ENQUIRY_FOLLOWUP where cef_mkey=enq.cef_mkey) and enq.activity_id not in (80,40) then 'Edit' else 'View' end ColViewEdit,

Answer 1

最后一行有两个AND：and and cef_mkey=2590。删除一个，这是无效的语法。

select enq.followup_sr_no ColFolSrno,case when enq.followup_sr_no=(select max(followup_sr_no) from  xxcus.XXACL_PN_ENQUIRY_FOLLOWUP where cef_mkey=enq.cef_mkey) and enq.activity_id not in (80,40) then 'Edit' else 'View' end ColViewEdit,

where  ENQ.FOLLOWUP_TYPE_ID = FOL.FOLLOW_TYPE_ID(+) and ENQ.PRIORITY_ID = PRI.PRIORITY_ID(+) and ENQ.ACTIVITY_ID = ACT.ACTIVITY_ID(+) and ENQ.NEXT_ACTIVITY_ID = NACT.ACTIVITY_ID(+) AND enq.flat_id = flt.flat_id(+) and enq.ATTENDED_BY_MKEY = em.USER_ID(+) and  cef_mkey=2590  order by enq.followup_sr_no desc

Answer 2

在最后一行查询中

where  ENQ.FOLLOWUP_TYPE_ID = FOL.FOLLOW_TYPE_ID(+) and ENQ.PRIORITY_ID = PRI.PRIORITY_ID(+) and ENQ.ACTIVITY_ID = ACT.ACTIVITY_ID(+) and ENQ.NEXT_ACTIVITY_ID = NACT.ACTIVITY_ID(+) AND enq.flat_id = flt.flat_id(+) and enq.ATTENDED_BY_MKEY = em.USER_ID(+) and  and cef_mkey=2590  order by enq.followup_sr_no desc

请注意，您连续两次使用AND运算符。

where  ENQ.FOLLOWUP_TYPE_ID = FOL.FOLLOW_TYPE_ID(+) and ENQ.PRIORITY_ID = PRI.PRIORITY_ID(+) and ENQ.ACTIVITY_ID = ACT.ACTIVITY_ID(+) and ENQ.NEXT_ACTIVITY_ID = NACT.ACTIVITY_ID(+) AND enq.flat_id = flt.flat_id(+) and enq.ATTENDED_BY_MKEY = em.USER_ID(+) and cef_mkey=2590  order by enq.followup_sr_no desc

这就是这条线应该是什么。

此外，如果您使用ANSI-92而不是ANSI-89语法（JOIN而不是FROM语句中的所有表），您可能不会收到此错误，因为您在WHERE子句中只有一个条件。
