MS Access seems to have its own logic for disaggregating a multi-table
JOIN against linked (Oracle) tables. Sometimes it sends the entire
JOIN to the Oracle database to have the JOIN performed on the Oracle
side, sometimes it disaggregates the JOIN query into multiple
single-table queries to retrieve individual table rows and then
perform the JOIN operation locally on MS Access.
I have not been able to detect any regularity or rules for this
behaviour.
Is there any way of controlling MS Access behaviour in how it sends
JOIN queries on linked tables to the remote database?
