| * The test variations execute only when the target database dictionary has |
| * a native sequence query defined. Even that condition is not sufficient for |
| * exclusion, since some databases support sequences, but not named sequences. |
| * For that reason, and due to specific configuration needs for some databases |
| * (Oracle) this test is allowed to fail. |
| * |
| * To run these tests successfully on Oracle a ORMSCHEMA user and SEQSCHEMA |
| * user need to exist. In addition, the Oracle user profile used to run the |
| * test must have SELECT object priviledge on the ORMSCHEMA.ORMSEQ and |
| * SEQSCHEMA.SCHEMASEQ sequences and CREATE ANY SEQUENCE (or equivalent) |
