General :: Cannot Get Android SQLite Select Statement To Work?

I'm trying to select the items that have a expiration date >= that an selected date.I'm using the format yyyy-mm-dd, and this is my sql statement:

String sql = "SELECT _id, item, value, finalDate FROM "+DATABASE_TABLE+" WHERE date(finalDate) >= date("+selectedDate+")";

This query always result a "full select" in my database, as if there were no conditions.Some useful information:

selectDate is a String which have a date in yyyy-mm-dd format
I'm executing the query like this:
return db.rawQuery(sql,null);
