reg---Self join in a table

Mon, 10 May 2010 10:47:26 GMT

Hi all,

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

empid is same as managerid.

empid	name	mgid
1	Alex	3
2	John	1
3	Ram	1
4	Sham	2

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

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
;

try in your load script

YourTable:
Load * from selfjoin.xls (...)

this will give you a table in QlikView named "YourTable"

now add the join according to Johns example.

Hi John, or someone else 🙂

Maybe this is not the right place to ask this question, but it has something to do with left joins, so I give it a shoot 🙂

I have 3 tables in my report, and I only want the orders witch are listed in my first table. Therefor, I have a Left Join on my 2'nd table load, in order to keep out any orders that are not listed in table 1.

But what can I write in my 3 load, in order to only keep the orders from Table 1?

If I write Left join on Table 3, my raport gets messed up. And if I leave out the Left Join, I get all the extra orders from table 3 in addition..

I hope I have been able to make my challenge clear for you to understand.

Table 1	Table 2	Table 3	Orders wanted in report
10	10		10
11	11		11
12		12	12
13	13	13	13
14			14
15			15
	16
		17
	18
	19
20			20
21	21		21
22		22	22

I appreciated any help I can get, and I am so thankful for anybody wanting to try to help me 🙂

*Newbee in love*

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 may have to post some sample data, because based on my understanding of what you're saying you're doing, there should be no problem, and you should get the exact result you posted. It sounds like you're doing something like this:

Table:
LOAD
Order
,Something
FROM Table1
;
LEFT JOIN (Table)
LOAD
Order
,SomethingElse
FROM Table2
;
LEFT JOIN (Table)
LOAD
Order
,SomeOtherField
FROM Table3
;

When you do the third load, the only Orders in Table should be the Orders originally loaded from Table1. Therefore, the left join should only take those orders from Table3, just like it did with Table2.

John: where did you find the ü on your keyboard?

Bharathe: try to put copied code into a section code /code both between square brackes []. Much nicer to read and looks professional
