[MS_AccessPros] Union Query load very slowly.

 

Dear All,

I have a union query behind a unbound subform as below. It takes about
0.5 minutes to load. Is that any way to improve the loading speed?
Thanks in advance.

SELECT
ID,LetterType,TransactionID,TransactionType,OfficeLocation,CostType,Amount,RecordDate,IIf([Checked]=True,"已审核","")
As
CheckAlready,GroupAndRemark,AccountID,ActualTransactionDate,Month(ActualTransactionDate)
As ActualMonth,ELookup("AccountName","tblAccount","AccountID=" &
Nz([AccountID],0)) As Account,Year(ActualTransactionDate) As
ActualYear,FinalAmount FROM qryaTransaction

UNION SELECT
ID,LetterType,ManagerialCostID,TransactionType,OfficeLocation,ManagerialCostType,Amount,RecordDate,IIf([Checked]=True,"已审核","")
As
CheckAlready,Remark,AccountID,ActualTransactionDate,Month(ActualTransactionDate)
As ActualMonth,ELookup("AccountName","tblAccount","AccountID=" &
Nz([AccountID],0)) As Account,Year(ActualTransactionDate) As
ActualYear,FinalAmount FROM qrybManagerialCost

UNION SELECT
ID,LetterType,PromotionCostID,TransactionType,OfficeLocation,PromotionCostType,Amount,RecordedDate,IIf([Checked]=True,"已审核","")
As
CheckAlready,Remark,AccountID,ActualTransactionDate,Month(ActualTransactionDate)
As ActualMonth,ELookup("AccountName","tblAccount","AccountID=" &
Nz([AccountID],0)) As Account,Year(ActualTransactionDate) As
ActualYear,FinalAmount FROM qrycPromotionCost

UNION SELECT
ID,LetterType,OtherIncomeID,TransactionType,OfficeLocation,OtherIncomeType,Amount,RecordDate,IIf([Checked]=True,"已审核","")
As
CheckAlready,Remark,AccountID,ActualOtherIncomeDate,Month(ActualOtherIncomeDate)
As ActualMonth,ELookup("AccountName","tblAccount","AccountID=" &
Nz([AccountID],0)) As Account,Year(ActualOtherIncomeDate) As
ActualYear,FinalAmount FROM qrydOtherIncome

UNION SELECT
ID,LetterType,OtherCostID,TransactionType,OfficeLocation,OtherCostType,Amount,RecordDate,IIf([Checked]=True,"已审核","")
As
CheckAlready,Remark,AccountID,ActualOtherCostDate,Month(ActualOtherCostDate)
As ActualMonth,ELookup("AccountName","tblAccount","AccountID=" &
Nz([AccountID],0)) As Account,Year(ActualOtherCostDate) As
ActualYear,FinalAmount FROM qryeOtherCost
ORDER BY 12, 11;

Best Regards,

Kevin
