I ran into this when I upgraded from 4.0.xx to 5.0.xx  There was a change in
the logic for the Joins.  I determined that the FROM clause needs to be in
parenthesis. i.e.    FROM (team, person, teamperson)  this allows all of the
fields in all of the tables to be used.  The change was made in mysql so
that only the last table (i.e. teamperson) was used for your JOIN

Subject: Join Suddenly Failing

I have a website that gets used once a year for a soccer tournament. It has
been working fine since 2006. No script changes since it was last used in
2009. All of a sudden the following script started throwing an error.

SELECT contactinfo.contactdata, contactinfo.ContactID FROM team, person,
teamperson
LEFT JOIN personcontact ON person.PersonID = personcontact.PersonID
LEFT JOIN contactinfo ON personcontact.ContactID = contactinfo.ContactID
WHERE team.teamID = 22
AND team.TeamID = teamperson.TeamID
AND teamperson.PersonID = person.PersonID
AND person.PeopleTypeID =5
AND contactinfo.ContactTypeID =2

Error: Unknown column 'person.PersonID' in 'on clause' (1054)

There are several of these type scripts and all are giving a similar error.

The server version is 5.0.87. I suspect the hosting company may have
upgraded to a new version of mysql.

Thanks.

Albert
