Question

I have a function that should delete a record in my sqlite database. But it is not deleting, what could be wrong?

public boolean deleteLoc(String id) {
    boolean deleteSuccessful = false;

    try {

        SQLiteDatabase db = this.getWritableDatabase();
        deleteSuccessful = db.delete(TABLE_NAME, "id =" + id, null) > 0;

    } catch (NullPointerException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return deleteSuccessful;

}

it always returns false.

Answer 1

try out this:

deleteSuccessful = db.delete(TABLE_NAME, "id ='" + id + "'", null) > 0;

otherwise there is no corresponding record in table…….have you checked your table for the entry you are trying to delete?
