Check if database exists and create table if it doesn't

[eluser]maddtechwf[/eluser]
I'm creating a plugin for a web app that was created with CodeIgniter. I'm trying to test to see if a table exists in the database and if it doesn't then I want to create the table with it's fields.

Any suggestions?

Code:

if ($this->db->table_exists('table_name'))
{
   // some code...
}

Would this work?

Code:

if($this->db->table_exists('my_tbl') == FALSE)
{
      call_function();
}

Yes, it returns TRUE or FALSE
