How to use Transformer with a Schema file

chitrangadsingh · Post by **chitrangadsingh** » Thu Aug 04, 2005 3:21 am

Hi,
Posting the query as a separate thread.

While using a schema file, if one has to do some transformations/calculations then how this can be done? I'm using run time col propagation and now there wont be any columns visible in the transformer (since the basic purpose of using schema file is to avoid using col defns). I actually tried putting in a transformer in b/w two seq file stages. The job ran and simply dumped the data into destination file.
Or is it so that schema file can only be used for simple load/extract?

Thanks,
Chits

Hi chitrangadsingh,
I'm also facing the same problem. May be your opinion is correct, i.e Schema file can be used only for extract/load purpose.

If anybody have any idea about this problem, pls help us.

I've not tried schema files yet, but it only makes sense that if you can't see the attributes when using them, and you need to make some transformations which will require you to see the attributes, then you will probably have to load the metadata.
