[PHP-DB] Return 1 instance of each unique record?
Hi everyone: How do I get MySQL to summarize a query so that I receive only 1 instance per similar record. I.E. if you have 10 records with name Smith and 5 records with Barney, etc, that it would return 2 records instead of 15. Thanks!

GROUP BY column The key is the GROUP BY part... check the manual for more of an explanation. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Try the MySQL DISTINCT feature. =dn -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks everyone... I find my problem often time is terminology. I am a FileMaker database developer and know the terminology of that database. I love MySQL, especially it's speed, but find crossing over sometimes difficult because the terminology is different and so I will do a search at MySQL on the terminology I'm used to, which in this case was summarize byand found nothing. Then I have to bother you guys to find out what the correct verbage is. Thank you for your patience!
