Counting in chart expression

Anonymous — Wed, 16 Dec 2009 01:01:06 GMT

Hi all,

I've a question regarding counting of children inside a hierarchy.

I have 2 fields: ID and ParentID.

I have to create a chart with ID as a dimension, and an expression that would count the number of children associated to the ParentID.

So, for example, if I have a table of IDs and ParentIDs

ID	ParentID
90	100
80	100
70	100
60	70
100	-

I wanted to have a resulting table chart like this:

ID	Children
100	3
90	0
80	0
70	1
60	0

How can I accomplish this task without writing load scripts?

I tried the expression:
count({<ParentID=ID>} ID)

but without any success.

Thanks.

Regards,
Valera

New chart (table type) -> add dimension ParentID -> add expression "=Count( Children )"

And uncheck "Supress zero values".

Well, I can't do that because all my tables are connected through the field ID and not ParentID. So, I am forced to insert ID as my dimension if I want to add also other related fields from different tables like Name, Date, PurchaseValue etc.

Any ideas?
