I have a web application that displays registrations for various events. When there are more than 100 registrations for an event I would like to break the display into pages of 100 registrations each rather than list all of the registrations on one page. In such cases I want to have a summary page that has links to each of registration pages along with the range of names covered by that page. For example, a summary page might say:
1-100 (Adams-Clark)
101-200 (Collins-Easton)
201-300 (Edwards-Granger)
and so on. I know I can do this relatively easily in Perl by (pseudo-code):
1. SELECTing the total number of registrations and dividing by 100 to
+get number of iterations for loop
2. for (index=1; index < num_iterations; index++){
SELECT RegistrantLastName FROM registrations ORDER BY Registrant
+LastName LIMIT (100 * (i-1)) + 1,1 AS RangeStart;
SELECT RegistrantLastName FROM registrations ORDER BY Registrant
+LastName LIMIT (100 * i),1 AS RangeEnd;
}
If possible, though, I would like to stick this all in a single query so that the DBMS is doing as much of the work as possible (and simplifying the logic in the application code).
Thoughts?
