Create table in SQLite only if it doesn't exist already

问题

I want to create a table in a SQLite database only if doesn\'t exist already. Is there any way to do this? I don\'t want to drop the table if it exists, only create it if it doesn\'t.

From http://www.sqlite.org/lang_createtable.html:

CREATE TABLE IF NOT EXISTS some_table (id INTEGER PRIMARY KEY AUTOINCREMENT, ...);
