public String getDbTable() {
    return db + DatabaseName.CAT_DB_TABLE_SEPARATOR + table;
  }
Get the name in db.table format, for use with stuff not yet converted to use the catalog.
Fair warning, that if the db is null, this will return null.tableName
@deprecated use {@link #getNotEmptyDbTable()} instead.
