Hi dathu,

please ask ur question clearly .... do u mean ur child means full_path or what ?

[#3]

FULL_PATH refers as a Tree and I want to load Final Node of FULL_PATH into report..

[#4]

FULL_PATH is unbalanced (n-level nodes) tree  and I want to load nth node  FULL_PATH on the tree.

[kuba_michalik]

Load first table, then do a resident load on it using the following condition:

Where not Exists(PARENT_ID, ID)

(remember to add NoConcatenate before this load or it will auto-concatenate)

Then drop the original table.

This will load only the nodes which have no descendants, so they must be the final nodes (leaves, or whatever the proper terminology is...)

Hi,

one solution could be:

or

tabApplications:
Hierarchy (ID, PARENT_ID, NodeName,, NodeName, PathName, '\', Depth)
LOAD ID,
    PARENT_ID,
    FULL_PATH,
    SubField(FULL_PATH,'\',-1) as NodeName
FROM [http://community.qlik.com/thread/138536] (html, codepage is 1252, embedded labels, table is @1);

Left Join
LOAD ID,
    If(FieldIndex('PARENT_ID', ID),Dual('No',0),Dual('Yes',-1)) as IsTerminalNode
Resident tabApplications;

hope this helps

regards

Marco

Check this qvw

vParntId=Concat(DISTINCT Chr(39) & PARENT_ID & Chr(39), ',')

Use the expression MaxString({<ID-={$(vParntId)}>} FULL_PATH)
