Hello,

 

I have an ESRI Geodatabase Reader using a WHERE clause (Parameters / Advanced / .. that works good.

 

Now I like to import Feature Types to perform the same query.

 

 

Unforunately the Where Clause needs the feature class name in the sub-query:

 

 

(ATTR1, ATTRDATE) IN (SELECT ATTR1, MAX(ATTRDATE) FROM SDE.FCNAME GROUP BY ATTR1)

 

 

So my question is: is there a way to set the where clause on the Feature Type level instead of the Reader level? Or is there a way to replace the feature class name with a variable/link that points to the appropriate Feature Type?

 

 

I appreciate any hint

A workaround might be to use a CREATOR and then a FEATUREREADER on that ESRI GDB. There you can specify the WHERE CLAUSE and have that reader only read that specific reader.

The FeatureReader seems to be a powerfull transformer. But I can't see a way to work with a customized WHERE CLAUSE for every feature type.  Or do I need to use multiple FeaturReaders?
