[teiid-issues] [JBoss JIRA] (TEIID-5900) query with local and remote pushes too much to remote

Ken Geis commented on TEIID-5900:
---------------------------------

I made the local table dependent with the MAKEDEP option, and that works. It does not make it dependent if I use the MAKEDEP hint in the FROM clause; only if I put it in the OPTION clause.

>    Affects Versions: 12.3.1

> I have a table "A" in an Oracle database. I have a date dimension "B" in Teiid, which is a materialized view of a recursive query. The date dimension has all dates from 1950 to 2050, 36890 rows in total.
> I run the following query:
> {code:sql}
> SELECT *
>   FROM a
>        JOIN b
>          ON a.date_column = b.date_key
> {code}
> Teiid sends a query to Oracle, which I will paraphrase as:
> {code:sql}
> SELECT <columns>
>   FROM a
>  WHERE date_column IN (to_date('1950-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'), 
>                        <36899 other date values!>)
> {code}
> Oracle breaks either with the length of the query or the number of options in the IN clause.
> I thought that MAKEDEP/MAKENOTDEP/MAKEIND could help, but they didn't seem to change anything.
