Subject: if defined on var

db =
Amalgalite::Database.new("/usr/local/vrep/repo/db/development.sqlite3")
table_exists = db.execute("select name from sqlite_master where
type='table' and tbl_name='derek'")

if defined?(table_exists)
   p "yes"
end
exit

Why does this print "yes"?  There is no table called derek in my DB.  In
fact it prints yes no matter what I type in for tbl_name.

My goal is to see if a table exists by testing the var holding the data
is true/defined or not.  Will you help?

thank you
derek!
