Help finding last record

[T.J.]

I have the following.

Category......StartPage#

Jazz..........1

Jazz..........1

Blues.........2

Blues.........3

Rock..........4

Rock..........5

I need to populate a new field that will contain the ending page number of the category. I’m not sure whether this requires a script that populates a global field or just a calculation field.

The end result would look like this.

Category....StartPage#....EndPage#

Jazz........1.............1

Jazz........1.............1

Blues.......2.............3

Blues.......3.............3

Rock........4.............6

Rock........5.............6

Rock........6.............6

Thanks in advance for any help.

Start with the last record and loop your way up with a script like this:

Sort // in the order of your example

Go to record (last)

Set variable ($cat ; "")

Loop

. If ($cat <> category)

.. Set variable ($cat ; category)

.. Set variable ($page ; StartPage)

. End If

. Set field (EndPage ; $page)

. Go to record (previous, exit after last)

End Loop

You could also create a self join

Tables:

Table 1

Table Selfjoin

(the relationship would be Category =Category) and sort descending by Start Page#

Then if you show Table Selfjoin::StartPage, you'll see the highest page#.

I'm attaching an example.

Hope this works :

Yet another way would be to use the Max function.
