In this case you're better off creating an RDBMS view and map your layer to the view.

Subject: [fdo-users] King Oracle join performance

When displaying data from a main SDE feature class table with about 1 million
entries, the King Oracle provider is very fast.

I need to filter the entries for security purposes. I have a secondary
non-SDE table that contains IDs from the main table that are available to
public users (about 900k entries). Joining this table to the main table in
an Oracle query (using SQL Developer) is just as fast as querying the main
table directly.

I've added the security table to the KingFdoClass table so that I can create
the same join in MGOS. When I try to view the resulting class in my map, the
viewer doesn't return -- it simply hangs while waiting for features from the

How can I debug this problem?
