Question

I am wonder about how to update the table.

I have use below two method to update the Table.

Which one is right one and Whats wrong in it ?
As i got the Exception while use both.

Code:

//First One For Update
public boolean setFavouriteBook(String id){
    String query = "update Articles set type = 0 Where address = '"+id+"'";
    myDataBase.rawQuery(query, null);
    return true;
}

// Second One for Update
//---updates a title---
public boolean setFavourite(String address) 
{
    ContentValues args = new ContentValues();
    args.put("type", 0);

    return myDataBase.update("Articles", args, "address = '"+address+"'", null) > 0;
}

And the Log is:

    02-08 10:29:56.010: INFO/Database(10350): sqlite returned: error code = 8, msg = prepared statement aborts at 28: [UPDATE Articles SET type=? WHERE address = '3']

Answer 1

If your database is in SDCard.

If you have your database in SDCard, so you have to give WRITE_EXTERNAL_STORAGE permission in your Manifest file. You can check this answer for the same problem.

Else you can use

SQLiteDatabase.OPEN_READWRITE instead of SQLiteDatabase.OPEN_READONLY while you are opening your database.

 checkDB = SQLiteDatabase.openDatabase(myPath, null,
                                                SQLiteDatabase.OPEN_READWRITE);
