insert into AIS20190505150649.dbo.HR_ATS_Holiday(FEmpID,FBillID,FHolidayTypeID,FSheetNo,FLeaveDate,FStartTime,FEndTime,FLeaveLength,FIsFullDay,FUnit,FLeaveReason,FIsContinue,FContinueTime,FSubmitDate,FStatus,FIsAgree,FAgreeUser,FCheckUser,FCheckTime,FRemark,FOperator,FOperatorIP,FOperateTime,FOperatorHost,FIsHarfDay,FSplit,FTotalLength,

FSubBillID,FRefLength,FCreatDate )

select FEmpID,FBillID,FHolidayTypeID,FSheetNo,FLeaveDate,FStartTime,FEndTime,FLeaveLength,FIsFullDay,FUnit,FLeaveReason,

FIsContinue,FContinueTime,FSubmitDate,FStatus,FIsAgree,FAgreeUser,FCheckUser,FCheckTime,FRemark,FOperator,FOperatorIP,FOperateTime,FOperatorHost,FIsHarfDay,FSplit,FTotalLength,

FSubBillID,FRefLength,FCreatDate  from HR201410.dbo.HR_ATS_Holiday

WHERE FSubBillID NOT IN (SELECT FSubBillID FROM AIS20190505150649.dbo.HR_ATS_Holiday )

我用这段语句把数据是同步过去了，但是A数据库中的FStatus字段值更新时，B数据中的FStatus不更新，请老师们指导一下，谢谢！

not in 效率较差改成join比较好
