Re: [MS_AccessPros] Replace field if another exists.


Here is example of what you are talking about I have in another application:

SELECT [Learning Center Non Client Activities].NonClientActivityID, [Learning Center Non Client Activities].LearningCenterID, [Learning Center Non Client Activities].ActivityDate, IIf(IsNull([ProgramName]),[LastName] & ", " & [FirstName],[ProgramName]) AS [Non-ClientName], [Learning Center Non Client Activities].Note, [Lookup Learning Center Client Activity Type].ClientActivityDetailName, [Learning Center Non Client Activities].ActivityTypeID
FROM [Learning Center Non Client Activities] INNER JOIN [Lookup Learning Center Client Activity Type] ON [Learning Center Non Client Activities].ActivityTypeID=[Lookup Learning Center Client Activity Type].ClientActivityDetailID;

 IIf(IsNull([ProgramName]),[LastName] & ", " & [FirstName],[ProgramName]) AS [Non-ClientName

But in my new case, Instead of ProgramName I have PersonID, BUt I need to use the DLOOKUP to pull the person name out of tblPerson based on the PersonID selected.

Sounds like you need an IIf function that tests the selection in the combo box and returns either the concatenated name or a DLookup to the other table.  Without more info, I can't give you specific code.

I have a query in which I need to display either the concatenated fullname or a name based on a ID in another table.

Select [FirstName] & " " & [LastName] as FullName, (or associated name from tblPerson if PersonID is selected, CitationID, Code, CitiationDate
FROM tblCitation

I would need to pull the [FirstName] & " " & [LastName] from tblPerson If the user selects a PersonID from the dropdown.

Clear as mud  know
