<blush> I have to learn to keep a 3x5 card with my column
headings nearby!!
But having corrected that, I'm running into another
problem.
I added:
if (!$result) {
echo "Could not successfully run query ($sql) from DB: ". mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
And they output nothing nowm so I assume that there are
things to print. But the "while" statement produces nothing
also.
Also, I think I misunderstood something someone saod
earlier. Is it true that the above mysql_query call does
not change the way the database is stored by simply sorts
the copy that's in memory?
Thanks.
