Data Type Mismatch with IIF Statements and InStr/InStrRev

Do you have null values in Manager_Name or Auditor_Name?

Yes there are some Manager and Auditor names that are null.

Then you need to screen out the null values, perhaps in a query, or in the expression itself, using Nz (check if Nz([Manager_Name]) = "", and don't parse it in that case).

Helen_Feddema:

So how would I incorporate that in this query statement:

FirstMgrName: IIf(InStrRev([Manager_Name]," ")=InStr([Manager_Name],",")+1,Mid([Manager_Name],InStr([Manager_Name],",")+2),Mid([Manager_Name],InStr([Manager_Name],",")+2,InStrRev([Manager_Name]," ")-InStr([Manager_Name],",")-2))

Thanks,

FirstMgrName: iif(isnull([Mnager_Name], null, IIf(InStrRev([Manager_Name]," ")=InStr([Manager_Name],",")+1,Mid([Manager_Name],InStr([Manager_Name],",")+2),Mid([Manager_Name],InStr([Manager_Name],",")+2,InStrRev([Manager_Name]," ")-InStr([Manager_Name],",")-2)))

Of course, you may want to try a copy of your table with all nulls removed, and make sure there isn't something else causing a problem, too.

It was because of null values.  I removed the records that contained nulls in the Employee, Manager or Auditor fields.  

I tried your query statement in your ID: 39279647 posting, but I get an error about invalid syntax.  Can you give me the correct syntax?

In the meantime, I just went ahead and added "Not Null" as the criteria on those 3 fields, so in the future if there are any nulls it will ignore them.

FirstMgrName: iif(isnull([Manager_Name]), null, IIf(InStrRev([Manager_Name]," ")=InStr([Manager_Name],",")+1,Mid([Manager_Name],InStr([Manager_Name],",")+2),Mid([Manager_Name],InStr([Manager_Name],",")+2,InStrRev([Manager_Name]," ")-InStr([Manager_Name],",")-2)))
I think. I missed an paren.

jerryb30:

Still getting invalid syntax.

select IIf(IsNull([Manager_Name]),Null,IIf(InStrRev([Manager_Name]," ")=InStr([Manager_Name],",")+1,Mid([Manager_Name],InStr([Manager_Name],",")+2),Mid([Manager_Name],InStr([Manager_Name],",")+2,InStrRev([Manager_Name]," ")-InStr([Manager_Name],",")-2))) AS FirstMgrName from table1

is working for me in Access 2003.

Ok. I got it to work, so not getting the syntax error anymore, but unless I have "Not Null" as the criteria for the Employee, Manager and Auditor, I'm still getting the "Data Type Mismatch" error, which is the initial reason I posted.

I have to step away for a bit.  Be back on line later.

Confused a bit. Can you post a sanitized DB, including a null Manager_Name?

I can handle up  to Access 2010.

jerryb30:

Ok.  I have Access 2007.

I've attached the database with a Manager Name that contains a null.  The query that I'm getting the Data Mismatch error on is "qryAssocReport".

The same error happens on the Employee and Auditor Names:

Employee:

FirstEmpName: IIf(InStrRev([tblEmployee_Audits].[Employee]," ")=InStr([tblEmployee_Audits].[Employee],",")+1,Mid([tblEmployee_Audits].[Employee],InStr([tblEmployee_Audits].[Employee],",")+2),Mid([tblEmployee_Audits].[Employee],InStr([tblEmployee_Audits].[Employee],",")+2,InStrRev([tblEmployee_Audits].[Employee]," ")-InStr([tblEmployee_Audits].[Employee],",")-2))

Select allOpen in new window

Auditor Name:

FirstAuditorName: IIf(InStrRev([tblEmployee_Audits].[Auditor_Name]," ")=InStr([tblEmployee_Audits].[Auditor_Name],",")+1,Mid([tblEmployee_Audits].[Auditor_Name],InStr([tblEmployee_Audits].[Auditor_Name],",")+2),Mid([tblEmployee_Audits].[Auditor_Name],InStr([tblEmployee_Audits].[Auditor_Name],",")+2,InStrRev([tblEmployee_Audits].[Auditor_Name]," ")-InStr([tblEmployee_Audits].[Auditor_Name],",")-2))

Select allOpen in new window

I'm not sure if the other fields that have InStr statements (like the Last Names for these) in them is causing issues as well, or just the ones that have IIf statements and InStr statements.

Your last posting worked.

Thanks much!


Here is my final code that worked:

For Employee:

FirstEmpName: IIf(InStrRev([tblEmployee_Audits].[Employee]," ")=InStr([tblEmployee_Audits].[Employee],",")+1,Mid([tblEmployee_Audits].[Employee],InStr([tblEmployee_Audits].[Employee],",")+2),Mid([tblEmployee_Audits].[Employee],InStr([tblEmployee_Audits].[Employee],",")+2,InStrRev([tblEmployee_Audits].[Employee]," ")-InStr([tblEmployee_Audits].[Employee],",")-2))

LastEmpName: Left([tblEmployee_Audits].[Employee],InStr([tblEmployee_Audits].[Employee],",")-1)

Select allOpen in new window

For Manager:

FirstMgrName: IIf(IsNull([Manager]),Null,IIf(InStrRev([Manager]," ")=InStr([Manager],",")+1,Mid([Manager],InStr([Manager],",")+2),Mid([Manager],InStr([Manager],",")+2,InStrRev([Manager]," ")-InStr([Manager],",")-2)))

LastMgrName: IIf(IsNull([Manager]),Null,Left([Manager],InStr([Manager],",")-1))

Select allOpen in new window

For Auditor:

FirstAuditorName: IIf(IsNull([Auditor_Name]),Null,IIf(InStrRev([Auditor_Name]," ")=InStr([Auditor_Name],",")+1,Mid([Auditor_Name],InStr([Auditor_Name],",")+2),Mid([Auditor_Name],InStr([Auditor_Name],",")+2,InStrRev([Auditor_Name]," ")-InStr([Auditor_Name],",")-2)))

LastAuditorName: IIf(IsNull([Auditor_Name]),Null,Left([Auditor_Name],InStr([Auditor_Name],",")-1))

Select allOpen in new window

Glad to help, but you would be better helped, if this is a beta database, to deal with how names are broken down/entered. And, maybe include 'Not Assigned' or 'Unknown' for the null fields, especially for Manager.
