You want SELECT DISTINCT ... or SELECT <column list> FROM <table> GROUP BY <column list>

In either case you probably can't use SELECT * - you have to specify the columns you're after. This is because these commands will look for any differences and if they see one they'll give you a new row; if all you're after is the userID use SELECT DISTINCT userID ... this will only return a particular value once.

See the documentation for your particular DBMS; GROUP BY is the more powerful with all kinds of aggregate functions available but sounds like SELECT DISTINCT will work fine for what your after.

Good Luck,

Subject: SELECT

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 =

$response_created_by = mysql_result($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.
