-----Original Message----- From: Fredrik Arild Takle [mailto:ftakle@xxxxxxxxxxxxxx] Sent: 03 May 2005 17:49 To: php-general@xxxxxxxxxxxxx Subject: Check for doubleposts Hi, what is the easiest way to check if a person i registered twice in a mysql-table. Lets assume that I only check if the last name is in the table more than once. This is in mysql 4.0 (subquery not an option). ----------- How about SELECT lastname, count(lastname) FROM table GROUP BY lastname HAVING count(lastname)>1 ---------- Do I have to use arrays and in_array. Or is there a more elegant solution? Best regards Fredrik A.
