  select distinct substr (:val, 1, 11) "Searchword",
                substr (table_name, 1, 14) "Table",
                substr (t.column_value.getstringval (), 1, 50) "Column/Value"
           from all_tab_cols,
                table
                   (xmlsequence
                       (dbms_xmlgen.getxmltype ('select ' || column_name
                                                || ' from ' || table_name
                                                || ' where upper('
                                                || column_name
                                                || ') like upper(''%' || :val
                                                || '%'')'
                                               ).extract ('ROWSET/ROW/*')
                   ) t
        where table_name in (SELECT table_name from all_tables)
        and owner NOT IN ('SYS','SYSTEM') and
        data_type IN ('CHAR','VARCHAR2') and
        data_length >= LENGTH(:val) and
        table_name in (SELECT table_name from all_tables);
