try

update test_table set column1=123 where column2 IN(100,200,300)

look here for a tutorial: http://www.webdevelopersnotes.com/tutorials/sql/tutorial_mysql_in_and_between.php3

If you mean that the match should happen where column2's value is one of the items in your list, use:

UPDATE test_table 
    SET column1=123 
        WHERE column2 IN (100,200,300, ...)

use FIND_IN_SET

FIND_IN_SET("id",test_table.column2)
