Way to frame an update query with parameters

Question

I am working on an application in Appcelerator Titanium. The application uses sqlite database. For inserting into the database, I have written a query with parameters like this:

db.execute("INSERT INTO formData (unique_id,form_xml_id,dateTime_stamp,data,user_id,status) VALUES ('" + Ti.App.mydata._guid + "'," + findex + ",'"+datetime+"','"+fdata1+"'," + Ti.App.information.user_id + ",'" + formstatus + "')");

I have another query to update the database for a different table. But the query is without parameters. Like this:

db.execute("UPDATE formData SET  form_xml_id=" + findex + ",dateTime_stamp='" + datetime + "',data='" + fdata + "',user_id=" + Ti.App.information.user_id + ",status='"+ DataStatus +"' where unique_id='" + Ti.App.mydata._guid + "'");

I want to rewrite the update query, like the insert query. How can I do that?

I have a code which update Contacts... you can modify it accordingly:

public int updateContact(Contact contact) {
        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues values = new ContentValues();
        values.put(KEY_NAME, contact.getName());
        values.put(KEY_PH_NO, contact.getPhoneNumber());

        // updating row
        return db.update(TABLE_CONTACTS, values, KEY_ID + " = ?",
                new String[] { String.valueOf(contact.getID()) });
    }
