Merge 2 tables for a SELECT query?

Question

First.. here are the two tables I\'ve created (sans irrelevant columns)..

CREATE TABLE users_history1 (
  circuit tinyint(1) unsigned NOT NULL default \'0\',         


        

Answer 1

Select col1 from test1 where id = '1'
union 
select * from table2 

this one can also used for the joining to tables.
