I added two custom profile fields...
one called:
ebayid
textline : 20 character limit

other:
ebayurl
textline : 30 character limit

I tried to update my ebayid and got a SQL error

General Error
SQL ERROR [ oracle ]

ORA-00911: invalid character [911]

SQL

UPDATE bb3_profile_fields_data SET _ebayid = NULL, _ebaylink = NULL WHERE user_id = 2
