Oracle tables without indices are not handled during convert - this behavior should be tolerant since Oracle does not require indicies.

While it is good practice to always have at least one index defined on every table, in some cases (such as temporary tables) indices are not necessary. Oracle does not enforce creating indices for every table, and it is common to create some tables without them. The Table.php (line 556) method throws an exception if an index is not found for a given table. It's obvious there are ramifications for findByPK( ) auto-generated methods - these should be generated for every case where PK exists to accommodate Oracle and tolerate variances from accepted best-practices with most other database platforms.
