android – sqlite onCreate()问题我希望我的数据库创建一次,它不会改变,但我在onCreate()时无法创建数据

public class EventsData extends sqliteOpenHelper {
       private static final String DATABASE_NAME = "events.db";
       private static final int DATABASE_VERSION = 1;


       public EventsData(Context ctX) {
          super(ctx,DATABASE_NAME,null,DATABASE_VERSION);
       }

       @Override
       public void onCreate(sqliteDatabase db) {

          db.execsql("create table " + TABLE_NAME + " (" + _ID
                + " INTEGER PRIMARY KEY AUTOINCREMENT," + TIME
                + " TEXT NOT NULL," + titlE + " TEXT NOT null);");

    //This doesn't work..
          db.execsql("INSERT INTO"+TABLE_NAME+"VALUES(null,'Hello','android');");
       }

       @Override
       public void onUpgrade(sqliteDatabase db,int oldVersion,int newVersion) {
          db.execsql("drop table IF EXISTS " + TABLE_Name);
          onCreate(db);
       }

    }
