SQLite error #3115 in Flex/Air App: with (')

Hi,

I am trying to do a simple SQLite query from inside and Air application:

var sqls:SQLStatement = new SQLStatement();

sqls.sqlConnection = sqlc;

sqls.text = "UPDATE videos SET thumb = 'ram's' where id = 2";

sqls.execute();

I need to add ' same as ram's

Error:

SQLError: 'Error #3115: SQL Error.', details:'near 's': syntax error', operation:'execute', detailID:'2003'

I'm using "addslashes()" but not working

Not sure why it does not work. Please help me.

Thanks,

Dhaval
