Question

This is a simple one! yet, I am missing something. Please help me out.
Here, I am trying to fetch values by id, but not able to do so. It is returning same values even after changing id’s value.

    db = openOrCreateDatabase("DBSOURCE", 0, null);
    Cursor cursorc = db.rawQuery("SELECT * FROM LIST WHERE ID="+id+"", null);
    cursorc.moveToFirst();

    int NameID = cursorc.getColumnIndex("Name");
    int mobilenumberID = cursorc.getColumnIndex("MoblieNumber");

    edName.setText(cursorc.getString(NameID));
    edMobNum.setText(cursorc.getString(mobilenumberID));

    cursorc.close();

    db.close();

Answer 1

1-
or better to use parametrized statement

String query = "SELECT COUNT(*) FROM " + tableName + " WHERE columnName = ?";
cursor = db.rawQuery(query, new String[] {comment});

2 – use if with conditon c.moveToFirst() or c.getCount() >0 or (!c.isAfterLast())

if (c.moveToFirst()){ 
    do{ 
       //if you not need the loop you can remove that
       id = c.getInt(c.getColumnIndex("_id"));
   }
 while(cursor.moveToNext());
}c.close();
