Hello -

I currently have 7 different tables that host documents and its pertaining demographics in Oracle Database. Problem - I'd like to create a union or some sort to concatenate all 7 tables into one so that I can load this into OBIEE to use to generate charts. Is there a way to combine all 7 into one (they all have the same dimensions)?

Best,

Andrew

    Hi,

    Do you look for a solution in OBIEE or in general in your DB?

    OBIEE can definitely manage your 7 tables and query them all together (defining 7 LTS for your logical table) or you can just "unify" them at the DB level. The simplest way is a view.

    I would avoid an opaque view in OBIEE as that's really hiding logic.

    I would avoid doing it with a VIEW in the DB but rater importing all 7 and use OBIEE's fragmentation if there is a way of telling to OBIEE which partition of data is within each table.

    The view option will always query all 7 sources while using fragmentation you'll hit only the fragment with the data you need if you specify the fragment partitioning key
