I saw syntax highlight error.

Question

SELECT COUNT(DISTINCT(a.create_member_id)) AS requestor_count FROM conv_conference a LEFT OUTER JOIN conv_conference_sessions b ON b.session_id = a.session_id
session_id is INT column, create_member_id is VARCHAR column. conv_confrence, conv_conference_sessions are TABLE.
session_id column on conv_confrence TABLE is foreign key to be connected with session_id column on conv_conference_sessions TABLE.
When I run it on SQL Developer 3.0.03.45, SQL Developer work NOT CORRECTLY! IT HIGHLIGHT character 'a' using blue color 3rd times. I seems to be a bug to me.
I have no Metalink/MOS. Thanks.
SELECT COUNT(DISTINCT(a.create_member_id)) AS requestor_count FROM conv_conference a LEFT OUTER JOIN conv_conference_sessions b ON b.session_id = a.session_id
ERROR POSITION 1 (a character only highlighted incorrectly) : ... --> a.create_member_id ...
ERROR POSITION 2 (a character only highlighted incorrectly) : ... --> a LEFT OUTER JOIN ...
ERROR POSITION 3 (a character only highlighted incorrectly) : ... --> a.session_id

Have you tried using another alias than a?
