DatabaseMetaData.getColumns: there is a typo in the JDBC specification, so that the column #19 is named SCOPE_CATLOG instead of SCOPE_CATALOG. For compatibility with the specification, this column is now also named SCOPE_CATLOG in H2. A new column named SCOPE_CATALOG is appended as column #24. Please note that MySQL only supports SCOPE_CATALOG, while other databases only support SCOPE_CATLOG.
