SQL question with Autocomplete functionality

[mazdotnet]

Hi,

I'm working on a little autocomplete functionality with the AJAX
toolkit. I like to the following,

Take the following 2 SQLs
SELECT NAME FROM COUNTRIES WHERE NAME LIKE '%TORONTO%' (would return
false)
SELECT NAME FROM CITIES WHERE NAME LIKE '%TORONTO%' (would return
true)

I like to have a stored procedure that does this. How do you write the
IF condition. Bascially I want it to first check the countries table
and if not matches there , next go to the CITIES table and check it
there? or is there a way to check both tables at once and return only
a single resultset combining both matches in COUNTRIES and CITIES
table? (in a single column 'Name'?)

Thank you
M.
