Tim,
The latest driver which is experimental doesn't throw an exception and I copied your lock as well
can you try it, it is the dev driver on the jdbc site.
let me know what else you find, if anything
Dave
For what its worth Dave, there are two places in my code where it the exception occurs and with both of them there is a prior statement to lock the table in share row exclusive mode. ie: Statement st = db.createStatement();
st.executeUpdate("lock table tablex in share row exclusive mode");
String statment = "select col1 from tablex where col2 = ?";
PreparedStatement ps = db.prepareStatement(statement);
ps.setString(1, col2text);
ResultSet rs = ps.executeQuery(); // <- Exception thrown here
It may be coincidental but I thought it would be remiss of me to leave it out.
Tim.

Yes, I can confirm that it does indeed throw an exception. I will have a look
at this shortly.
Thanks,
