How to display the first and second Doctor to see a patient?

    I have to create a table where there are lots of columns pulling date from one table and two views. To display the columns is no problem. The problem comes into play when I have to alias two columns to show a patient who received services from the first two distinct doctors (doctor_1 and doctor_2). Each doctor has their own ID. I’m not sure if I should use the “distinct top (2)”, “rank”, etc… Here is what it sort of looks like.

    Date, LastName, FirstName, Address, City, State, Zip, Hostital, Room, Doctor_1,Doctor_2

    Any help would be greatly appreciated.

    Hi,

    One way is "Top 2" of doctors in a subquery and link it to patient table to get your data extract.

    Can you confirm that you are using SQL Server 2000?
