Question

I’ve created a SQLite Android dB in my app. I can add info to the dB without any problem. But I’m not able to delete anything from it.

This is my code:

        final SQLManager hon = new SQLManager(this);
        b.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        // TODO Auto-generated method stub

           long l = 3;
           hon.open();
           hon.deleteEntry(l);
           hon.close();
        }
                });

And here is the method “deleteEntry()”:

       public void deleteEntry(long l) {
   // TODO Auto-generated method stub
   ourDatabase.delete(DATABASE_TABLE, null, null);
       }

It was supposed to delete the whole dB, wasn’t it? The button which makes the delete function when pressed is in the same view than the dB, is this a problem?

Answer 1

you can use the following code

ourDatabase.execSQL("delete from <TableName>");
