  • 0

I have a Oracle database where I have to use sequences for the primary key. This all works well as I have control over the sequence number. My problem is with my tests. Using Spring I create an HSQL db and test against this. This database is constructed by looking at all my entities. All my entities for the sake of working with Oracle have a sequence name specified. The trouble is that when I construct the HSQL db it cannot find the sequence (which I expect) My tests pass but I end up with lots of cruft in the log. The log is filled with these sort of messages.

WARN JDBCExceptionReporter:233 - SQL Error: -5501, SQLState: 42501
ERROR JDBCExceptionReporter:234 - user lacks privilege or object not found: GENDERS_SEQ

Does anyone know how I can remove these spurious errors? Can I get HSQL to ignore the sequences. Interestingly in the tests I can insert into the HSQL database so it must be using its own internal primary key generator.

Anyone any ideas on how I can remove this cruft from the log?

Thanks

    I solved this by manually creating sequences as part of my test script. Not ideal as I would rather Spring/HSQL combination set this up. My code is:

    for (String sequence : sequences) {
    entityManager.createNativeQuery("DROP SEQUENCE " + sequence + " IF EXISTS").executeUpdate();
    entityManager.createNativeQuery("CREATE SEQUENCE " + sequence + " as INTEGER").executeUpdate();
}

    where sequences is a list of string which are the sequence name.

    I used this is the @BeforeClass method for each test class. Not ideal but it does solve the problem
