複数のテーブルを1つのANDROID DB名に作成する際にエラーが発生しました

Question

1つのDBで2つのテーブルを使用しているときに問題が発生しました。 SINGLE DBで複数のテーブルを使用して私を助けてください。

ここでは、同じDB名のProperty &という2つのテーブルがあります。

property.class

You should create multiple tables in single db name in this fashion: 


public class EventDataSQLHelper extends SQLiteOpenHelper{ 
    private static final String DATABASE_NAME = "My_moodledata1.sqlite"; 
    private static final int DATABASE_VERSION = 1; 

    public EventDataSQLHelper(Context context) { 
     super(context,DATABASE_NAME, null,DATABASE_VERSION); 
     // TODO Auto-generated constructor stub 
    } 


    @Override 
    public void onCreate(SQLiteDatabase db) { 
     // TODO Auto-generated method stub 
     final String CREATE_TABLE_SITEINFO = 
       "CREATE TABLE siteinfo(id INTEGER PRIMARY KEY AUTOINCREMENT,sitename TEXT,username TEXT,firstname TEXT,lastname TEXT,fullname TEXT,userid TEXT,siteurl TEXT, userpictureurl TEXT,userpassword TEXT,photo BLOB);"; 
      db.execSQL(CREATE_TABLE_SITEINFO); 
      final String CREATE_TABLE_SYNCHRONISE = 
        "CREATE TABLE synchronise(id INTEGER PRIMARY KEY AUTOINCREMENT ,filetype TEXT, filepath TEXT,link TEXT,datetime Text);"; 
      db.execSQL(CREATE_TABLE_SYNCHRONISE); 
      final String CREATE_TABLE_COURSEINFO = 
        "CREATE TABLE courseinfo(id INTEGER PRIMARY KEY AUTOINCREMENT ,courseid TEXT, shortname TEXT,fullname TEXT,userid Text,sitename TEXT);"; 
      db.execSQL(CREATE_TABLE_COURSEINFO); 
      final String CREATE_TABLE_PARTICIPANTINFO = 
        "CREATE TABLE participantinfo(id INTEGER PRIMARY KEY AUTOINCREMENT ,courseid TEXT,userid Text,participantid TEXT ,fullname TEXT,email Text,description TEXT,city TEXT,country TEXT,imagesmall TEXT,imagelong TEXT,smallphoto BLOB,largephoto BLOB);"; 
      db.execSQL(CREATE_TABLE_PARTICIPANTINFO); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // TODO Auto-generated method stub 

    } 

}
