Question

这是我的数据库列：你看到在最后一栏我把BLOB。

  @Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL("create table " + TABLE_NAME + " (ID TEXT PRIMARY KEY,PASSWORD TEXT,FNAME TEXT,SNAME TEXT,BIRTHDATE TEXT,MATHGROUP TEXT,GENDER TEXT, PROFILEIMAGE BLOB)");
}

我要求用户从图库中选择一张图片。图像保存在位图中。我有位图位图。当我想插入数据时，我需要将位图转换为byte []。这样：

ByteArrayOutputStream stream1 = new ByteArrayOutputStream();
                        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream1);
                        byte [] buffer = stream1.toByteArray();

我插入数据。（该方法在DatabaseHelper类中定义。）

   boolean isInserted = myDb.insertData(editID.getText().toString(),
                                editPASSWORD.getText().toString(),
                                editFNAME.getText().toString(),
                                editSNAME.getText().toString(),
                                datePickerBIRTHDATE.getDayOfMonth() + "." + datePickerBIRTHDATE.getMonth() + "." + datePickerBIRTHDATE.getYear(),
                                spinnerMATHGROUP.getSelectedItem().toString(), spinnerGENDER.getSelectedItem().toString(), buffer );

我成功插入了。所以现在第一个用户就是sigen-up。但我现在不能做更多。如果用户输入ID并通过，我开始检查与他的详细信息匹配的数据详细信息，该应用程序失败（带注释）！我无法访问数据库信息。问题是肯定的BLOB列（或我放入它使数据库崩溃）。我假设因为当我删除该列时，我对登录没有任何问题。代码有什么问题吗？

这是Logcat

在数据库中存储位图。怎么了？
