Вот такая ошибка.

SQL Error [19114] [72000]: ORA-19114: error during parsing the XQuery expression:
ORA-06550: line 1, column 13:
PLS-00201: identifier 'SYS.DBMS_XQUERYINT' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

В чем проблема и как исправить. Благодарен за любые наводки.
