具有datediff（天未给出正确答案的Coalesce函数）>

Question

[这是我用来获取帐龄桶的查询，很多帐户属于正确的桶。但很少有帐户甚至没有落入任何账龄账单。

ArBal现场实验室应落在正确的老化桶支架之下。

,case WHEN DATEDIFF(day,COALESCE(bv.DischargeDateTime,bv.ServiceDateTime,bb.CutoffDateTime,bv.AdmitDateTime),GETDAT E()) > 90 and DATEDIFF(day,COALESCE(bv.DischargeDateTime,bv.ServiceDateTime,bb.CutoffDateTime,bv.AdmitDateTime),GETDAT E()) < 121 and  bvfd.BarStatus ='FB' then isnull(bvfd.Balance,'0') ELSE '' END 'AR_91_120'

,case WHEN DATEDIFF(day,COALESCE(bv.DischargeDateTime,bv.ServiceDateTime,bb.CutoffDateTime,bv.AdmitDateTime),GETDATE()) > 120 and  DATEDIFF(day,COALESCE(bv.DischargeDateTime,bv.ServiceDateTime,bb.CutoffDateTime,bv.AdmitDateTime),GETDATE()) < 151 and  bvfd.BarStatus ='FB' then isnull(bvfd.Balance,'0') ELSE '' END 'AR_121_150'

,case WHEN DATEDIFF(day,COALESCE(bv.DischargeDateTime,bv.ServiceDateTime,bb.CutoffDateTime,bv.AdmitDateTime),GETDATE()) > 150 and  DATEDIFF(day,COALESCE(bv.DischargeDateTime,bv.ServiceDateTime,bb.CutoffDateTime,bv.AdmitDateTime),GETDATE()) < 181 and  bvfd.BarStatus ='FB' then isnull(bvfd.Balance,'0') ELSE '' END 'AR_151_180'

,case WHEN DATEDIFF(day,COALESCE(bv.DischargeDateTime,bv.ServiceDateTime,bb.CutoffDateTime,bv.AdmitDateTime),GETDATE()) > 181 and  bvfd.BarStatus ='FB' then isnull(bvfd.Balance,'0') ELSE '' END 'AR_181_Plus'

但是我应该在相应的账龄时段中获得ARBal字段..但是我确实看到帐户3和4的全零。请帮助我

将整个查询发布在这里
