[Forum] MySQL errors: blank queries?

[Zackw]

Hi, this is probably a simple or even a normal thing, but I'm just curious. In the log file I'm fairly free of errors, but the ones that seem common are where the query text is empty, like this:

Database error in vBulletin 4.1.3:

Invalid SQL:

    SELECT thread.firstpostid
    FROM thread AS thread
    WHERE thread.threadid =;

MySQL Error   : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3

As you can see this was from mobiquo, but still. Under what circumstances would the forum try to query with an empty value? That is, thread.threadid = blank?

This isn't the only error. I have another from a moderator in the inlinemod.php script that got this query:

Invalid SQL:
UPDATE user SET usertitle = 'Banned', usergroupid = '10', displaygroupid = '0' WHERE userid=;

Why would any script give a blank value like this?

Thanks

Any ideas?

I have the same issue.
Did you ever find a solution on this?
