where table1 has column month with data form开发者_Go百科atted like so: 01, 02, 03

Simplest way might be to just cast it to an int:

SELECT CAST(month as int) from table

From the MySQL docs:

mysql> SELECT MONTH('2008-02-03');
-> 2

So, if you only have the month (and not the rest of the date), you could use:

SELECT MONTH(CONCAT('2010-', month, '-', '01')) FROM table1;
