Compare strings as numbers in SQLite3

I have the following query in SQLite:

SELECT * FROM t1 ORDER BY t1.field

Where t1.field is a text column containing numbers. Is it posible to force SQLite开发者_如何学运维 to consider the values of t1.field as numbers instead of strings (whithout doing ALTER TABLE)? Right now the sort is a pure string one, so 10 goes before 2.

Thank you.

Well, found a solution:

SELECT * FROM t1 ORDER BY t1.field + 0

The + 0 part seems to force conversion to number
