SQLite에서 특정 데이터를 가져와
다른 Activitiy에서 값을 저장하려고 하는 도중에 sql부분에서 오류가 뜹니다.
일단 데이터를 모두 가져와서 열로 비교를 하려고 하는뎅..
public class LoginActivity extends AppCompatActivity {
DBHelper_User db;
List<UserModel> list;
TextView Idinput, Pwdinput, Nameinput;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Nameinput = (TextView)findViewById(R.id.inputName);
Idinput = (TextView)findViewById(R.id.inputId);
Pwdinput = (TextView)findViewById(R.id.inputPwd);
final EditText LogId = (EditText)findViewById(R.id.logID);
final EditText LogPwd = (EditText)findViewById(R.id.logPWD);
Button LogBtn = (Button) findViewById(R.id.Login);
Button Regist = (Button)findViewById(R.id.Regist);
db = new DBHelper_User(this);
final UserModel model = new UserModel();
list = db.GetAllUser(); DB에서 불러오는 부분입니다.
public List<UserModel> GetAllUser(){
StringBuffer stringBuffer = new StringBuffer();
stringBuffer.append("SELECT _ID, UserId, UserPwd, UserName FROM User order by _ID desc");
SQLiteDatabase sdb = getReadableDatabase();
Cursor cursor = sdb.rawQuery(sdb.toString(), null);
List<UserModel> userList = new ArrayList<UserModel>();
Log.d("RESULT",cursor.getCount()+"");
UserModel user = null;
while (cursor.moveToNext()){
user = new UserModel();
user.ID = String.valueOf(cursor.getInt(0));
user.UserId = cursor.getString(1);
user.UserPwd = cursor.getString(2);
user.UserName = cursor.getString(3);
userList.add(user);
}
sdb.close();
return userList;
}여기서 Cursor부분에서 syntax error가 뜹니다ㅠㅠ
