Have you considered the GROUP BY statement of SQL??
For example if this is a table's data:
msg_id user varname value 2 1 yada hello 3 1 yada hows it going? 4 2 yada its me! Zonk! 6 1 turmoil anyone here seen that movie before? 8 2 turmoil oh yeah, years back! 9 1 yada and that means??you can: $request_varname="yada"; SELECT * FROM the_table WHERE varname = "$request_varname" GROUP BY user HAVING max(msg_id) If I can recreate my "in brain" SQL engine correctly this sql should work.. I'm not sure of exactly what your setup is like relating to storage of the data, and I'm not certain I understand what you are trying to retrieve with your query either, but I hope I'm heading down the right track.. I'm sure either way that its the GROUP BY predicate you are after.. enjoy!~ ---oOo--- Allowing users to execute CGI scripts in any directory should only be considered if: ... a..

I am trying to put together a SELECT syntax. I am querying a response database and I only want to obtain each user's name once even if they have given more than 1 response. $query="SELECT * FROM conversation_table WHERE conversation_reference = $conversation_currently_displayed"; $response_created_by = mysql_result($result,$i,"response_created_by"); My ideal is that if users 1, 2, 4 & 5 are in dialogue with each other the above SELECT $query will only give the results of their identity once with the mysql_request() function Thanks for your help.
