SQLiteConstraintException không đi vào bên trong bắt

Question

Khi tôi chạy mã mà tôi có bên trong db.insert một ngoại lệ:

08-29 15:40:17.519: E/SQLiteDatabase(3599): android.database.sqlite.SQLiteConstraintException: column date is not unique (code 19) 

Đó là bình thường, bởi vì tôi đã có giá trị như một chìa khóa. Vì vậy, trong trường hợp đó tôi bắt được SQLiteConstraintException nhưng tôi không bao giờ bị kẹt bên trong khi tôi chạy mã.

Tôi đang làm gì sai?

  try { 
       db.insert(TABLE_STATISTICS, null, values); 
      } catch (SQLiteConstraintException e) { 
       Log.d("entered", "entered the exception"); 
       ContentValues valuesUp = new ContentValues(); 
       valuesUp.put((isMT ? KEY_MT : KEY_MO), change); 
       db.update(TABLE_STATISTICS, valuesUp, KEY_DATE + "=?", 
         new String[] { message_date }); 
      } 

Cảm ơn bạn.

Sử dụng db.insertOrThrow() để thay thế.
