I had an update like this:

update table set col1=?,col2=?,col3=? where col4=?;

and I filled it up like this:

statement.setString(1,"some_value");
statement.setString(2,"some_value");
statement.setString(3,"some_value");

and I forgot to add a fourth value.I did a executeUpdate and of course nothing happened to the database. I spent about 1 hour debugging it, to see where it goes wrong. I then modified my code to print the SQLWarning object returned by the getWarnings method. It always returned null. I even modified the code to the buggy state it was, before I set the fourth parameter, and still no warning. Does anyone know how one can get an error/warning?

If it matters, my Connection is set to autoCommit.
