Workaround for ORA-01722 SQL error “ORA-01722: invalid number”, triggered when used on Oracle 11g database charset Unicode AL32UTF8.
NLS_NUMERIC_CHARACTERS seems linked ; Oracle differs from mariadb on dates (bug when especially creating a quizz "pairing")
This workaround solves the problem.
Check with SELECT TO_NUMBER('-,5') FROM DUAL
Please note following requirement to use moodle 36 on Oracle ; install :
* DBMS_LOB to manage CLOB ; execute ```GRANT EXECUTE ON dmbs_lob to <<schema>>```
* DBMS_RANDOM
* DBMS_LOCK
When searching in a glossary, box "search in definitions" uncheck, a debug info appears. It deals with ORA-06502 complaining about a string too short on MOODLELIB:86 (stacktrace lib/dml/moodle_database.php:486 dmi_read_exception thrown) Apply this workaround and recompile package moodlelib brings things OK.
