Does this driver support the ANSI-92 entry level SQL grammar? All JDBC Compliant drivers must return true. We currently report false until 'schema' support is added. Then this should be changed to return true, since we will be mostly compliant (probably more compliant than many other databases) And since this is a requirement for all JDBC drivers we need to get to the point where we can return true.
