@boubcher The Esri Geodatabase (File Geodb Open API) reader only supports WHERE on Feature Types, not at the reader level. Most other database readers (including Esri Geodatabase (File Geodb)) support a WHERE at both the reader level (not that useful) and on the Feature Types.
The FeatureReader currently only supports the WHERE at the reader level, not on individual feature types. Hence WHERE isn't available for the Esri Geodatabase (File Geodb Open API) reader in the FeatureReader but it is for Esri Geodatabase (File Geodb) reader. For most other databases the FeatureReader WHERE applies to all feature types that are read (which isn't that useful).
The plan is to update the FeatureReader to support all the reader feature type parameters.
