* 'select where' using multiple columns.

Hi,

I've googled around for this but can't see a decent way of doing this :

I've got a persons name which is being stored say in 3 columns :-  
Title, Forename_1, Forename_2, Surname. I want to allow a search say for 
'John Smith'. Problem is I can't just break it up into forename and 
surname because I won't also know.
Is there a way to do something like a
'select * where forename_1,forename_2,surname like '%String%'   ??

Thanks for any help. Apologies if its a FAQ.

Rob

SELECT * FROM table WHERE forename_1 || ' ' || forename_2 || ' ' ||
surname LIKE '%String%';

Try this way:

select * .... where forename_1||' '||forename_2||' '||surname like '%String%'

or

select * .... where forename_1||' '||forename_2||' '||surname~'String'

You could try the following, but it won't get a medal for performance...

SELECT * FROM xpto WHERE forename_1 LIKE '%String%' OR forename_2 LIKE 
'%String%' OR surname LIKE '%String%'
