谢谢travylee 我想要的是三列数据第一列是batchid，第二列是在表一中ph_batchid=表二中batchid并且ph_phaseid=2的时间差的和。第三列是是在表一中ph_batchid=表二中batchid并且ph_phaseid=8的时间差的和
请教sql语句怎么写啊？
select BatchID,
SUM(case when ph_phaseid=2 then DATEDIFF(s,ph_start,ph_end) else 0 end) [ph_phaseid=2],
SUM(case when ph_phaseid=8 then DATEDIFF(s,ph_start,ph_end) else 0 end) as[ph_phaseid=8]
from(
select a.BatchID,b.ph_start,b.ph_end,b.ph_phaseid from [vAPVrsCIPBatchList] a
left join [PhaseHold] b on a.BatchID=b.[ph_batchid])t
group by BatchID
