I am not positive, but I think that is the correct order. This had been discussed before and ofcourse, with my limited brain capacity I can't remember.

Hi DBAs,

Can someone clarify/confirm on how Oracle determines what table to use in select statement?

For ex. If I am login as Scott and do the following:

SELECT * FROM employee;

Of course Oracle will use Scott.employee if it exist. If it does not exist but exist under another schema. Does
Oracle look at private synonyms then public synonyms or vice versa.

My guess is Oracle checks in this order. Please confirm or correct.

  1. Check if table exist in current schema
  2. Check private synonyms
  3. Check public synonyms
  4. 3 strikes your out with an error.
