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.
