SQLite不能识别插入

想要在表单中新加入一行然后确认是否加入正确，等到查询的时候，程序就崩溃了。
addNewGame(1);

Cursor cursor2 = db.query(myDBOpenHelper.GAMES_TABLE, new String [] {"MAX("+GAME_COLUMN+") AS GC"}, null, null, null, null, null);
System.err.println("made it this far");     
String temp = cursor2.getString(cursor.getColumnIndex("GC")); //crash!!!
System.err.println("didn't get here);


private static void addNewGame(int g) {
        ContentValues newValues = new ContentValues();
    SQLiteDatabase db = DBOpenHelper.getWritableDatabase(); 
    newValues.put(GAME_COLUMN, g);
    newValues.put(CIV_COLUMN, "");
    db.insert(myDBOpenHelper.GAMES_TABLE, null, newValues);
}
thread exiting with uncaught exception
创建表单的代码：
private static final String GAMES_CREATE =  "create table " +
            GAMES_TABLE + " (" + KEY_ID +
            " integer primary key autoincrement, " +
            GAME_COLUMN + " text not null, " +
            CIV_COLUMN + " text);";
db.execSQL(GAMES_CREATE);
