I am using ormlite in my recent android project. I want to order by on a query on multiple columns in a table (say two columns). How can I achieve that??

    All you need to do is to call orderBy(...) multiple times.

    qb.orderBy("VISIT_DATE", false);
    qb.orderBy("order-column", false);
    ...
    

    This is covered by the documentation. To quote:

    Add "ORDER BY" clause to the SQL query statement to order the results by the specified column name. Use the ascending boolean to get a ascending or descending order. This can be called multiple times to group by multiple columns.

    Also the javadocs:

    Add "ORDER BY" clause to the SQL query statement. This can be called multiple times to add additional "ORDER BY" clauses. Ones earlier are applied first.
