reg---Self join in a table

Hi all,

In a excel sheet i m having empid,empname,managerid.

empid is same as managerid.

empidnamemgid
1Alex3
2John1
3Ram1
4Sham2


here i want to display the names of manager.

If i click 1 in empid, i want to generate Ram as manager name....

If i click 2&3 in empid ,i want to display Alex as manager name....

if 4 in empid, i want to display Johnas manager name...

In the source file no manager name is given.

How to achieve this?

thanks in advance,

Bharathe

I gave you half the script, Jürg gave you the other half, and he told you to put his half first, my half second. Doing exactly what he said, you'd get this:

YourTable:
Load * from selfjoin.xls (biff,embedded labels,table is sheet1$)
;
LEFT JOIN (YourTable)
LOAD
empid as mgid
,name as "Manager Name"
RESIDENT YourTable
;

And that should work. It may not be exactly what you want, though. Presumably, you've already written the script to load from selfjoin.xls. We're not telling you to change that script AT ALL. All we're telling you to do is add MY script after it, and replace "YourTable" with the name you gave your table (and not with selfjoin.xls, which is your data source, not the name of your table). If your table is named "Employees" for instance, replace "YourTable" with "Employees" in the two spots it appears in the sample script I gave you.

You can reload this script and see what's happened. I think it's the best way to understand.

Employee:
HIERARCHY (EmployeeID, MgrID, Employee, Manager, Employee, Path, '/', Depth)
LOAD EmployeeId as EmployeeID,
Name as Employee,
MgrID,
Salary;
LOAD * INLINE [
EmployeeId, Name, MgrID, Salary
1, Anthony, 5, 8000
2, Peter, 5, 8500
3, Keanu, 5, 10000
4, William, 5, 20000
5, Jessy, 5, 50000
6, Toto, 3, 40000
7, Titi, 3, 20000
];

If you're only going up one level in the hierarchy, then perhaps this is a simpler solution than a hierarchy load:

LEFT JOIN (YourTable)
LOAD
empid as mgid
,name as "Manager Name"
RESIDENT YourTable
;
