쿼리를 사용하여 사용자 데이터를 검색하는 방법

Question

사용자가 의사에게 일정을 요청할 수있는 프로젝트 앱이 있습니다.

내 문제는 선택한 의사를 기반으로 환자 데이터를 검색하고 의사 프로필에 ListView으로 표시하는 방법을 모르므로 의사가 로그인 할 때 환자가 일정을 요청할 수 있음을 알 수 있습니다.

Answer 1

쓰기 당신의 SqlDbHelper 클래스에서이 방법

public ArrayList<String> getPatientNames(String docId) { 

    ArrayList<String> list = new ArrayList<String>(); 
    String query = "Select * from DATABASE_TABLE_PATIENT where _id ='" 
      + docId+ "'"; 
    SQLiteDatabase db = this.getWritableDatabase(); 
    Cursor cursor = db.rawQuery(query, null); 

    if (cursor.moveToFirst()) { 
     do { 

      db.beginTransaction(); 
      try { 
       list.add(cursor.getString(3)+" "+cursor.getString(4)+" "+cursor.getString(5)); 
       db.setTransactionSuccessful(); 
      } catch (SQLException e) { 
       e.printStackTrace(); 
       db.endTransaction(); 
      } finally { 
       db.endTransaction(); 
      } 
     } while (cursor.moveToNext()); 
    } 
    return list; 
} 

위 메서드는 메서드에 전달 된 의사의 "_id"에 해당하는 모든 환자의 이름 목록을 반환합니다.

String query = "SELECT * FROM " + TABLE NAME + " where "+ PAT_ID + "='" + user Id + "'"; 

SQLiteDatabase db = dbHelper.getHandle(); 

cursor = db.rawQuery(query, null);  
cursor.moveToLast();  
startManagingCursor(cursor); 

if (cursor.moveToFirst()) {  
    do {  
     // do .... 
     String id = cursor.getString(0);  
    } while (cursor.moveToNext());  
}
