SQL order by query results in any arbitrary (but reproducible) manner

For testing purposes I need to get some data from a set of database tables in any arbitrary (but reproducible) order. The idea being that I can later compare two runs using a textual diff tool. Is there an idiom for that? E.g. I can obviously do a: SELECT * FROM table_with_N_columns ORDER BY column_1, ... , column_N I am just asking if there is an idiomatic way to achieve the same effect (for my purposes) without bothering to list every column in the ORDER BY clause. Any ordering will do so long as it is reproducible with subsequent runs of the query.
