MySQL - Is it possible to use LIKE on all columns in a table?

MySQL - Is it possible to use LIKE on all columns in a table?

I'm trying to make a simple search bar that searches through my database
for certain words. It is possible to use the LIKE attribute without using
WHERE? I want it to search all columns for the keywords, not just one.
Currently I have this:
mysql_query("SELECT * FROM shoutbox WHERE name LIKE '%$search%' ")
Which obviously only searches for names with the search input. I tried
both of these:
mysql_query("SELECT * FROM shoutbox LIKE '%$search%' ")
mysql_query("SELECT * FROM shoutbox WHERE * LIKE '%$search%' ")
and neither worked. Is this something that is possible or is there another
way to go about it?
