Hi:

 

 

What would be a work around to filter the features in the FFS reader, similar to other data readers that have the WHERE Clause parameter?

Hi,

 

Place a tester or testfilfer after the reader .

No.. this approach I want to exclude,  I have a big FFS file( =long time for reading), that I don't want to read its whole content in order to pick certain records .

Hi,

 

 

The query functionality like "WHERE Clause" seems to be available only in a dataset which will be accessed from the reader via middle ware having a query mechanism (typically DBMS: database management system).

 

I don't think FFS has such a mechanism, unfortunately.

Hi, I imagine you create the ffs file yourself, since it is an FME format. Why not create/prepare different ffs files, with the right TestFilters? Best regards, Jelle

Other the using the features type to read parameter and the suggestions here, you are out of luck....
