Yes, you can re-select from the same database without opeing a new connection.
I recommend that you print the contents od $newquery to verify it contains the string you think it should. Perhaps the apostrophes you've enclosed the $row[] variable are not expanding. -----Original Message----- From: Jonathan Underfoot [mailto:[EMAIL PROTECTED]] Sent: Friday, February 08, 2002 7:43 AM To: [EMAIL PROTECTED] Subject: [PHP-DB] MySQL / PHP Database Help I'm trying to write a script that checks for multiple entries on a table in a database. So far I've been plagued by MySQL errors. I'm fairly confident my scripting is ok (Then again, I've been wrong before.) I think moreover there might be some difficulty with my theory. Then again, I could try and do this with MySQL join statements. Any feedback would be appreciated. $sqlquery = mysql_query("SELECT * FROM local_shows"); while ($row = mysql_fetch_array($sqlquery)) { $newquery = mysql_query("SELECT * FROM local_shows WHERE show_date='$row[show_date]' AND venue='$row[venue]'"); while ($row2 = mysql_fetch_array($newquery)) { $num_rows = mysql_num_rows($row2); if ($num_rows>1) { print "etc etc" (Do things with my $row2 data) I get loads of: Warning: Supplied argument is not a valid MySQL result resource in /home/ufr2/underfoot-www/admin/dupeshows.html on line 51 Can you not reselect in another while while selecting? Does that make any sense to anyone but me? I shouldent have to open another DB connection? Anyhow... your I would appreciate any help. -Jonathan -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
