Thanks for your great response.
That makes sense. I tried to put some output in the loop that goes through
each record, but it seems that the delay is before that, perhaps here:
// delay is with this command
$theresults=mysql_query( $sql )
//then it is ok here and processes loop quickly
while( $row = mysql_fetch_object( $theresults ) )
I think it is because it is loading in over 80000 records from mysql
database in this query?
Is there a command or other method I can use that will not load the whole
dataset at once, but only one record at a time? Please assist
Thanks so much
Julie
