How do I check two tables is it? Username and userpass are submitted

$sql = "SELECT username, userpass FROM mytable, mytable2 WHERE
username = '$username' AND userpass = '$userpass'";
This way you'll have an ambiguous error as username and userpass
belongs to both table (as far as I could understand). You can do both
selects or do something like this:
select a.user, a.pass, b.user, b.pass
from table1 a, table2 b
where (...)
Or create a MERGE storage engine if both your tables are identical:

Or if your tables are not identical you can use a LEFT JOIN:
