stacking two tables - response (3) by ena

thanks dnoeth!
one thing more. i have two tables- but table 1 has two extra column. is it still possible to union the.
for eg; table 1- pol_cnl_typ,campaign_descrip,cnl_code
and table 2 -pol_cnl_typ
How can i union them. I do not want to alter my original table here as that will confuse other users.
