Help with simple query

Posted on 16th Feb 2014 07:03 pm by admin

Hi,

I'm trying to do a Query with a Union where I want to print the number of rows $tc contains. Can anyone see what's wrong with this:

Code: $tc = @mysql_num_rows(mysql_query("(SELECT * FROM tbl1 WHERE id = $id) UNION (SELECT * FROM tbl2 WHERE id = $id)"));
print $tc;
