Why do I get an error that looks something like this:
"Warning: 0 is not a MySQL result index in <file>
on line <x>" or "Warning: Supplied argument is not
a valid MySQL result resource in <file> on line <x>?
You are trying to use a result identifier that is 0. The 0 indicates
that your query failed for some reason. You need to check for errors
after submitting a query and before you attempt to use the returned
result identifier. The proper way to do this is with code similar
to the following:
$result = mysql_query("SELECT * FROM tables_priv");
if (!$result) {
echo mysql_error();
exit;
}
or
$result = mysql_query("SELECT * FROM tables_priv")
or die("Bad query: ".mysql_error());
