update from 的问题
update CsoKPIBase a set F_ASPNodeTotalCsoQty = (select count(Key) as sum_qty, ASPNode from CsoKPIBase
where
ServiceType<> 9
and ServiceType<> 11
and ServiceType<> 12
and InternalCloseTime >= to_date('2012-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
and InternalCloseTime <= to_date('2012-12-12 23:59:59', 'yyyy-mm-dd hh24:mi:ss') group by ASPNode)b
where a.ASPNode=b.ASPNode
应该怎么改啊?我这样写报错,求高手指导
------解决方案--------------------
update CsoKPIBase a set F_ASPNodeTotalCsoQty = (select count(Key) as sum_qty from CsoKPIBase c
where
c.ServiceType<> 9
and c.ServiceType<> 11
and c.ServiceType<> 12
and c.InternalCloseTime >= to_date('2012-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
and c.InternalCloseTime <= to_date('2012-12-12 23:59:59', 'yyyy-mm-dd hh24:mi:ss')
and c.ASPNode=a.ASPNode
group by ASPNode
)b
要是CsoKPIBase 查不到a.ASPNode 会 更新成空值的哦
