Re: [libreoffice-users] LibréOffice Base Forms, PostgreSQL (JDBC) and Table Joins

Alex,

Thanks for the follow-up.

Ideally there'd be one form for the asset(s), wherein each value
could be entered or altered, the ones being foreign key references
presenting a list from the desired column in the table to which the
FK references.

For example: I can do an ad hoc query that looks roughly like

    select ..., s.desc as "status", ... from hdwr_assets h
      left join hdwr_status s on s.status_id = h.status_id...;

and a field named "status" will show in the output.

Ideally, I'd like to be able to do that.  In fact: I *can* do that in
Queries -> Create Query in Design View), but not in a form?

Behind the scenes: When you clicked on a list box for "status" in the
assets form, a list derived from "descr" in the status table would be
presented. When a selection is made, the related status_id value
would be placed in the status_id field for the selected hardware
asset.

A sub-form would (could?) be presented, allowing one to alter the
status table.

Btw: When I try to associate hdwr_assets.status_id to
hdwr_status.status_id using the Forms Wizard, execution results in

    Error: The data content could not be loaded.
    Error: SQL Status: 22023
     The column index is out of range: 1, number of columns: 0.
    Information: The SQL command leading to this error is:

     SELECT * FROM "public"."hdwr_status" WHERE ( "status_id"
     = :link_from_status_id )

Which is not valid SQL.

I would have thought this functionality would be present.  Even the
most basic of database normalization in the most trivial of databases
is going to result in multiple tables and FK references.

Thanks,
Jim
