Hoping someone can help me out here . . .
I have a table that contains a number of records. It has two fields, "Starter" and "Main Course". Typical data would look like this. . .
etc . . .
I need to try and select all similar pairs that occur in the table more than once. For example, in the above table, I would be looking to select Soup and Beef and Salad and Pork as they occur more than twice.

Off the top of my head, something like:
SELECT Starter, Main, Count(Main)AS cnt FROM my_table WHERE cnt>1;
should get you a list of any duplicates.
