Hi
Try to download tUnPivotRow at Exchange.
tUnPivot will change columns into rows.

Hi,
ou can unpack the component in a folder on your local system. After that, in Studio, you click Window -> Preferences, in the pref window you click Talend->Components.
There you specify the folder you unpacked the component in.
Now you should have the new component in your Pallet.
Hope this helps!

Arno

Hi
Here is the tested data.

00001;2,000;3,000;2,500
00002;2,200;3,000;1,000

Create job as the following images.
pivot_key and pivot_value must be defined in the schema.
Or you will get errors.
Best regards

Hi
Which version of TOS do you use?
First, change the type of pivot_value into Integer.
Then click "Code" tag and check the Java code of your job.
Or email me and attach your job.

Pedro

Hi Pedro,
My TOS version is 4.2.3 for Win32.
This Job can't export due to error of compiling.
and I couldn't choose pivot_key and pivot_value in schema.
How should I do next?

Hi
This must be a compatibility issue.
Because i can run this component correctly with JDK1.6.0_11(Win XPSP3).
But when it comes to JDK1.6.0_29(WIN7 32bit), it fails.
Now i try to test it in Linux.
I will update this component in my spare time.
Regards,
Pedro

Hi,
Thank you for your response.
Is this problem about version of JDK?
Incidentally, my environment is for XP.
