Hello Hans-Georg,
I tried to reproduce the described behavior, but the query you have shown worked well for me. Here is the SQL statement that was generated by OpenAccess:
Can you please try to execute the statement directly on your database, in order to see if you have the same problem here? Please adjust the table and column names, so that the statement matches your schema.
Can you also provide the statement that is generated by OpenAccess and the structure of your table? It would be helpful if you can send me a DDL Script, which I can use to generate the same database schema locally and reproduce the error.
We are looking forward to hearing from you.
Best wishes,
Ralph
