SQlite select statement

Question

У меня есть оператор sqlite, но он дает мне ошибку в where where и в функции sres.getsrthreadid, где предложение возвращает мне MAC-адрес с некоторым номером наконец. Моя функция:

SResponses sres=new SResponses(); 
String queryz = "SELECT " + MySQLiteHelper.COLUMN_ID + "," + MySQLiteHelper.COLUMN_MESSAGE+","+MySQLiteHelper.COLUMN_THREADID+","+MySQLiteHelper.COLUMN_POSITION + " FROM " + MySQLiteHelper.TABLE_NAME + " WHERE "+MySQLiteHelper.COLUMN_THREADID+ "="+sres.getsrthreadid(); 

Log.e("datasource", sres.getsrthreadid()); 
cursors = database.rawQuery(queryz, null); 

Logcat является:

Answer 1

Quote ваше значение входного сигнала, так что SQLite может получить его правильно:

String queryz = "SELECT " + MySQLiteHelper.COLUMN_ID + "," + MySQLiteHelper.COLUMN_MESSAGE+","+MySQLiteHelper.COLUMN_THREADID+"," 
+MySQLiteHelper.COLUMN_POSITION + " FROM " + MySQLiteHelper.TABLE_NAME + " WHERE " 
+MySQLiteHelper.COLUMN_THREADID+ "='"+sres.getsrthreadid() + "'; // Here 

Answer 2

Просто замените код с этим

SResponses sres=new SResponses(); 
String queryz = "SELECT " + MySQLiteHelper.COLUMN_ID + "," + MySQLiteHelper.COLUMN_MESSAGE+","+MySQLiteHelper.COLUMN_THREADID+","+MySQLiteHelper.COLUMN_POSITION + " FROM " + MySQLiteHelper.TABLE_NAME + " WHERE "+MySQLiteHelper.COLUMN_THREADID+ "='" + sres.getsrthreadid() + "'"; 

Log.e("datasource", sres.getsrthreadid()); 
cursors = database.rawQuery(queryz, null);
