Subject: [PHP-DB] PHP/MySQL Question
HI,
New to PHP/MySQL,
I was wondering if this was possible.
I have a users database with an auto-incremented userID field.
I have another message database (it's a message board database) - one of
the fields is a TEXT field with userIDs separated by carriage returns;
eg; if on one record userID 2 and userID 4 have both viewd that record,
the data in that field will look as follows:
2
4
I want to construct a SQL query for every user that logs in (I am
storing their userID as a session variable) so that I can filter out any
messages where a user has already viewed that record. So in the above
example that record should be filtered out if user 2 or user 4 has
viewed the record.
The query I constructed is:
SELECT * FROM messages WHERE userID != '$userid'
But this will not filter out any records like the one above where the
userID in the message database is separaed by carriage returns as above
(ie; it won't filter out messages for user 2 or user 4).
Hope this makes sense
Peter
