请问一下SqLite的query方法

Cursor cur = db.query(TBL_NAME, null, where, args, null, null, null);SqLite的query方法，参数args中不能含null值。会报错:
ERROR/AndroidRuntime(844): java.lang.IllegalArgumentException: the bind value at index 2 is null但是我只知道下面这样写，请问要实现这样的逻辑该怎么写?
Cursor cur = db.query("info", null, "number is ? and name=?", new String[]{null,"ming"}, null, null, null);
