Android Sqlite: Select only specific Column from a table?

:)

I have a table Customer with 3 fields (id, name, email) and I'd like to get only the name of all customers and show it on a Spinner. Any idea on how I could do it?

How I get all data

public Cursor getAllData ()
{
    String buildSQL = "SELECT * FROM " + DatabaseHelper.Customers.TABLE; 
    return database.rawQuery(buildSQL, null);
}

DatabaseHelper file, with the table and column

public static class Customers
{
    public static final String TABLE = "customers";
    public static final String _ID = "_id";

    public static final String NAME =  "name";
    public static final String EMAIL = "email";

    public static final String[] COLUMNS = new String[]
    {
        _ID, NAME, EMAIL
    };
}

I thought about using

String buildSQL = "SELECT * FROM " + DatabaseHelper.Customers.COLUMNS; 

But i am not sure how I could retrieve the name only. Any tips? Thanks on advance, guys!
