             lastposter, thread.dateline, IF(views<=replycount, replycount+1, views) AS views, notes, thread.visible, sticky, votetotal, thread.attach
             " . iif($vboptions['threadsubscribed'] AND $bbuserinfo['userid'], ", NOT ISNULL(subscribethread.subscribethreadid) AS issubscribed") . "
             " . iif(!$deljoin, ", NOT ISNULL(deletionlog.primaryid) AS isdeleted, deletionlog.userid AS del_userid,    deletionlog.username AS del_username, deletionlog.reason AS del_reason") . "

mysql error: Column: 'lastpost' in field list is ambiguous

Means that the column 'lastpost' is found in to tables that are in the query. SQL don't know which instance of lastpost you mean.

You should use a syntax like:

[sql]SELECT a.ambiguousfield, b.ambiguousfield FROM tablea AS a, tableb AS b[/sql]

Using the "table AS xx" you can create a short name to refer to a table, then prefix the column with that shortname and a dot.

PS This is general info as i didn't even tried to read your query

miz · #3 01-24-2005, 02:33 PM

hmm with out adding the user part its working fine i also tried with FROM user AS user
but still same error

Marco van Herwaarden · #4 01-24-2005, 02:42 PM

Well both the thread and the user table got a column called 'lastpost'.

So you would have to refer to that column by either user.lastpost or thread.lastpost

        ORDER BY sticky DESC, lastpost DESC

should fix it.

You are using the column 'lastpost' more then once, so you should also change it more then once.
