Rave reports. generate data page number limit

Question

How can i put a limit to generate a page. on the rave reports?

let say the user selected all data to print and it will generate a 1,000+ pages.

but i wanted to limit it to 100 pages only is that possible?

You limit the data so that there's only enough available to print 100 pages worth of output. You can do this by using better WHERE clauses, a TOP condition (or whatever similar option your database allows) or a FILTER condition if you're not using SQL. — Ken White, Mar 20 '12 at 12:43
yes i did. but it just used in case scenario like user really wanted to view it thousands of pages. so i have to limit the page that can be generated or else it eats a lot of memory usage and causing the machine to crash. — XBasic3000, Mar 20 '12 at 14:14
That's what I said. Use your query or a filter condition to only return a maximum number of rows, no matter what the user says or does. — Ken White, Mar 20 '12 at 15:23

Right now you have something like this on the Delphi side:

txtQuery := 'SELECT * FROM table WHERE date BETWEEN "2001-01-01" AND "2013-01-01"';
query.SQL.text := txtQuery; //This being the Component assigned to your TRvDataSetConnection
prjRave.execute;

You should add something like this to your txtQuery:

txtQuery := 'SELECT * FROM table WHERE date BETWEEN "2001-01-01" AND "2013-01-01" LIMIT 500';

That way, no matter how much data is requested by your user, you get a maximum of 500 rows on your Rave Report.
