Anyone familiar with Oracle (the DB)? I need your help!
Bugzilla installations running Oracle as their database server fail to display flags, tags and keywords in buglists. Oracle crashes with:
DBD::Oracle::db prepare failed: ORA-30482: DISTINCT option not allowed for this function (DBD ERROR: error possibly near <*> indicator at char 313 ..., group_concat(<*>T_CLOB_DELIM(DISTINCT map_tag.name, ', ')) tag
All the details are in bug 780053. The group_contact() function is defined in Bugzilla/DB/Oracle.pm. The maintainer of the Oracle DB module, who was an Oracle employee, disappeared, leaving us in the dust. The code in Oracle.pm is totally obscure to us and I have no idea how to fix it. I would like to have this bug fixed on time for Bugzilla 4.4, which should be released before the end of the year, and so I need your help as soon as possible to fix this problem. Someone already made a suggestion in the bug, but I need a second review or another sugggestion as I don’t understand anything about the cryptic internals of Oracle.
So if you are familiar with Oracle or use Oracle as your DB server, please give it a look. Many thanks!
