How do I perform the following queries?

1) What is the number of reports which are coded with either an "a" or "b" where the last "a" or "b" code of the report (in document order) is an "a"?

(correct number is 3. Yes, this has been double checked.)

Which is to say that there is a code list with a code "a" where there are no following code lists with a code "b".

Unfortunate that I couldn't apply them to my application because my example was too simplified.

Below is what you asked for ... perhaps this will help you.
