mysql_selectdb() vs. mysql_select_db()

[vethost]

I read in the PHP site, "For downward compatibility mysql_selectdb() can also be used. This is deprecated however."

I'm trying to install a third-party script, but keep getting this error:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/user/www/base_top_v.php on line 16

The code snippet including Line 16 in base_top_v.php reads:

<? $accounts = mysql_query("select * from banners where id >= '1' order by name asc");
$total_found=mysql_num_rows($accounts);
srand(date("s")); $number = rand() % $total_found;
if ($number == "0") { $number = 1; }
while ($get_rows=@mysql_fetch_array($accounts)) {
$ccc = $ccc + 1;
if ($ccc == "$number") {
$banner_url=$get_rows[banner_url];
$link_url=$get_rows[link_url];
}
} ?>

I've narrowed it down I think to the use of mysql_select_db() in the script. I am not running the latest version of Mysql, so I was wondering if I should seek out all the occurences of that term and replace it with mysql_selectdb()

Any thoughts? I'm running mysql 4.0x

I don't think that's the problem -- if your query is failing for some reason, you'd get the same error. Try adding "or die mysql_error()" and see what you get.

I am a noob. Where exactly do I put that snippet?

Thanks!

After the mysql_query() call.

Thanks. I tried adding it several times in different ways and get "Parse error: parse error, unexpected T_STRING"

Does that mean you didn't get it do work? See [a href=\"http://ca.php.net/mysql_error\" target=\"_blank\"]here[/a] if you're still having trouble.
