Ambiguous column name in Output Set Report

Hi Troy

You mentioned you have the Search HH checked and I suspect your element is checked as a single row (constituency = was my clue). In that case, in the Where Clause part for TR_QUERY_ELEMENT make the statement

!.constituency = <<p4>> and !.end_dt is null

If you don’t have !. for where clause fields you get the ambiguity error when you have a combo of Search Household and Single row. The idea is that it acts like the Membership elements – if the constituent on your list has the data then that data is output (even if the household also has the data). If the constituent doesn’t have the data, but the household does then the household data is output. So you only ever get one row output.

!. is used by the aliasing process you noticed in RP_RUN_QUERY

Hope that resolves it for you!

Subject: [Tessitura Technical Forum] Ambiguous column name in Output Set Report

Greetings,

I have a output set consisting of a Constituency End Date that is looking for a NULL value. I have set up the fields where the data select is !.end_dt looking at the view VXS_CONST_CUST. The where area is defined as:

constituency = <<p4>> and end_dt is null

The output set has this and nothing else. A search HH is checked. I receive an error message that states:

The columns constituency and end_dt are ambiguous. I was peering into RP_RUNQUERY and noticed that there is only one table alias allowed for the work table, hence the error. Has anyone worked out the solution to something like this?
