Report module: LOV with two columns

Question

I would like to create a LOV with two columns in a designer generated report module.
scott@ntw>select deptno, loc
  2  from dept;
    DEPTNO LOC
        10 NEW YORK
        20 DALLAS
        30 CHICAGO
        40 BOSTON
        50 LAS VEGASIs it possible to create the lov of the report module with an indivdual select statement?
Does anyobody have an idea?

Hi,
There are probably a number of ways that you can handle this, but the underlying principle for all of these would be that you need to have 2 reports. The first report would contain the first ten records and the second report would contain the next ten.
The way to do that would be to get the ROW_NUMBER() value for each line and, in the query defintion for each report, you would have a WHERE clause that restricted the results based on this value. The best way to do this would be to create a view and base the reports on this view. The view definition would include:
ROW_NUMBER() OVER (ORDER BY xxxx) AS ROW_NUMBER
where xxxx is the same order definition as the main ORDER BY clause. Each row will then get a ROW_NUMBER value that matches it's position in the query resultset.
Your first report would then have a WHERE clause of:
WHERE ROW_NUMBER < 11
the second report would have:
WHERE ROW_NUMBER BETWEEN 11 AND 20
The final step would be styling/positioning the reports. The first would probably be in Column 1 in the region and the second in Column 2. You would almost certainly have to adjust the styling and/or positioning using a style attribute in the region/report definitions.
