"来自"附近的SQLite异常

Question

我只是从我的SQLite数据库中获取数据,它说当编译从联系人编号中选择smss组时,'from'附近的语法错误.这是我的代码:

 public ArrayList<Sms> fetchScreenedSms() {
ArrayList<Sms> smsInbox = new ArrayList<Sms>();
String query_fetchSMS = "select from smss" + " group by contactnumber " + "\"" ;
DBtableforNotSpam smsD = new DBtableforNotSpam(this);
SQLiteDatabase dbw = smsD.getWritableDatabase();

我也试过这个,但它仍然说同样的话:

String query_fetchSMS = "select from " + "smss" + " group by contactnumber " + "\"" ;

请指导我这里的问题

Answer 1

指定columnName或*(适用于所有列)

String query_fetchSMS = "select * from smss group by contactnumber";
