MS Access：您输入的表达式太复杂了

Question

我试图在以下更新查询中调用此VBA函数，并且我收到此错误。我被卡住了，我不知道该怎么做。函数签名对我来说似乎没问题。

Compute([ep].[ReferenceNumber],[ep].[ITU3Number],[ep].[AuthorizationNumber],[ep].[Ent],[ep].[Indicator],[ep].[LineCode],[ep].[ProductLinee],[ep].[Inp_ProfitCenterCode],[ep].[Inp_ParisBOCode],[ep].[StartDate],[ep].[EndDate],[ep].[ExtractionDate],[ep].[OffBalance],[ep].[IType],[ep].[Counterparty],[ep].[WAL],[ep].[Inp_BackupLineIndicator],[ep].[Indicator],[ep].[FinalRating],[ep].[Amount],[ep].[Currency],[ep].[Historical],[ep].[rice],[ep].[MaturityIndicator],[ep].[pproachType],[ep].[SignatureDate],[ep].[IMaturityDate],[ep].[ProductType],[ep].[Inp_StepupDuration],[ep].[ProbabilityOfStepup],[ep].[SCF],[ep].[ICollateralSCF],[ep].[MobilFlag,[ep].[MarginBp],[ep].[ExtensionCode],[ep].[ExtensionYear],[ep].[UsageType],"a","a")

Answer 1

对于访问进程，表达式太长了：

最大可接受长度似乎约为560个字符最大参数数似乎为29。

例如，通过截断某些字段，可以正常工作：

Compute([ep].[ReferenceNumber],[ep].[ITU3Number],[ep].[AuthorizationNumber],[ep].[Ent],[ep].[Indicator],[ep].[LineCode],[ep].[ProductLinee],[ep].[Inp_ProfitCenterCode],[ep].[Inp_ParisBOCode],[ep].[StartDate],[ep].[EndDate],[ep].[ExtractionDate],[ep].[OffBalance],[ep].[IType],[ep].[Counterparty],[ep].[WAL],[ep].[Inp_BackupLineIndicator],[ep].[Indicator],[ep].[FinalRating],[ep].[Amount],[ep].[Currency],[ep].[Historical],[ep].[rice],[ep].[MaturityIndicator],[ep].[pproachType],[ep].[SignatureDate],[ep].[IMaturityDate],[ep].[ProductType],[ep].[Inp_StepupDuration])

这有效：

Compute(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29)

但这失败了：

Compute(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30)

所以，你可以这样做：

Compute(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,SubCompute(29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56))
