The title's it, really.

With .TAB file reader, you can add multiple layers to the reader and use the 'merge feature type' check box with an '*' to read all the layers listed in the source files, which can then be separated out again on featuretype name.

With the SQL Server Spatial reader, you can specify many layers in the database selection, but it seems that the 'merge feature type' option doesn't work.

Is this a bug, or expected behavior, or am I missing something?

EDIT: I have found that I can do this sometimes... so the above may be incorrect. I'll need to test some more.

Use the FeatureMerger or Joiner - details on how and when to use them evangelism.safe.com/fmeevangelist79 – Mapperz♦ Jan 15 at 4:23
Nono, I don't want to merge the features together. Just read them all in with one reader to simplify the workspace. The joiner reads attributes from another source and appends then to features, while the featuremerger does the same with already read features. I just want more than one feature type in one reader. – alexgleith Jan 15 at 4:27
I think it works the same, the only difference is you have to specify the Feature Types to Read parameter. – blah238 Jan 15 at 9:03
FME will read any features and convert on the fly to .ffs (it's own bespoke format) regardless of format. Database Connections require to be separate. – Mapperz♦ Jan 15 at 15:41

It does work for me - using a PostGIS database. I made a short video to demonstrate the process, just in case something isn't clear.

By checking the dynamic option, all I'm doing is setting "feature types to read". But, as someone else mentioned, you do need to ensure the Feature Types to Read parameter includes your required tables (or is empty and so reads all of them).

If you still can't get it to work, I suggest contacting the Safe support team at http://www.safe.com/supportrequest

The FME Evangelist! Congrats on the 2013 release. Confirmed on grouping by the "fme_feature_type" - I just tried with Oracle Spatial, and without grouping, the output was very trashy. Once enabled, it output as expected. – Mintx Jan 15 at 20:20
