Question

Hi all im using a sqlite helper class, but i have a little problem using a select statement.
I want to get the id of a datebase item by its name.

I use this select method:

public Cursor selectShift (String name){
    SQLiteDatabase db = dbHandler.getReadableDatabase();
    Cursor c = db.query(TABLE_NAME, null, "name=" + name, null, null, null, null);
    c.moveToFirst();
    db.close();
    return c;
}

And when i call this i use this:

if(handler.selectShift(name)!=null){
      Cursor c = handler.selectShift(name);
      id = c.getInt(c.getColumnIndex("_id"));
      c.close();      
  }

And then is get this error:

android.database.CursorIndexOutOfBoundsException: Index 0 requested,
with a size of 0

As if its not exists, but i checked the name string is correct, and when i display the names in a listview i see that name, so it exists.

Can someone help me how to fix this?

Thanks for your help, i found the problem. It was in the cursor method, the solution is:

public Cursor selectShift (String name){
    SQLiteDatabase db = dbHandler.getReadableDatabase();
    Cursor c = db.query(TABLE_NAME, new String[] {"_id"}, "name LIKE '"+name+"%'", null, null, null, null);
    c.moveToFirst();
    db.close();
    return c;
}
