I'm facing the following problem.
I have a database with two tables, t1 and t2. The two tables have the same
simple structure, say columns col1, col2. What I want to do is to select
from t1 and, in case no results are returned, to then select from t2.
Right now, all I'm doing is
SELECT col1 FROM t1 WHERE col2 = "STH"
SELECT col1 FROM t2 WHERE col2 = "STH";
That is, as far as I know, I always check both t1 and t2 and, moreover, I
get no guarrantee that t1 entries will come first in the list of the
Any ideas on how to solve this?
