    Unanswered: Subtracting a subset of a table

    Hi. Using Hyperion Client for Oracle I am having trouble with the following issue:

    I have a master table of data. In a separate table I have a subset of the master data. I would like to create a new table that contains the entries on the master that do NOT appear on the subset table. I want to subtract the subset from the master and be left with a new table.

    in terms of a join it might be something like:

    Table 1 contains the master
    Table 2 contains a subset of the master
    JOIN: Retrieve all rows where joined columns do NOT match

    Anyone have any thoughts on this?

    Many thanks.
