To access feature type parameters, click the gear icon 
on a feature type in the workspace to open the Feature Type Parameter Editor. To always display the editor in Workbench, you can select View > Windows > Parameter Editor.
General
All feature types share similar General parameters, which may include the Feature Type Name, Reader or Writer Name, and Geometry.
In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept a Table Qualifier prefix on the output table feature type.
See Editing Writer Feature Types for more information.
These parameters apply only to a selected feature type, not to the entire reader.
Note: If a feature type parameter corresponds to a reader-level parameter, then the reader parameter will be ignored and the feature type parameter will be used.
Constraints
These parameters are passed to the Query API endpoint of the Feature Service. For more information about these parameters, refer to the corresponding page in the ArcGIS REST API documentation.
WHERE clause
Optionally specifies the SQL-style WHERE clause applied to object fields to limit the set of features returned. Attribute names are case-sensitive, and the types of values must match the type defined in the schema.
Input Geometry
Optionally specifies the geometry to apply as the spatial filter.
The value should be valid Esri GeoJSON, a point of the form x,y, or a bounding box of the form xmin,ymin,xmax,ymax.
Note: The coordinate system is assumed to be the same as the layer’s coordinate system, unless the Input Geometry is Esri GeoJSON and specifies its own coordinate system.
Input Geometry Type
The type of geometry specified in the Input Geometry parameter. The server will return an error if the Input Geometry is not of the specified type.
This parameter is ignored if Input Geometry is not specified.
Options: Envelope (default), Point, Polyline, Polygon, Multipoint
Spatial Relationship
The type of spatial relationship to use with the Input Geometry.
This parameter is ignored if Input Geometry is not specified.
Options: Intersects (default), Contains, Crosses, Envelope Intersects, Index Intersects, Overlaps, Touches, Within
Distance
The optional buffer distance for the Input Geometry. Applies to all Input Geometry types.
This parameter is ignored if Input Geometry is not specified.
Units
The units used for the Distance parameter.
This parameter is ignored if Input Geometry is not specified.
Options: Meters (default), Miles, Feet, Kilometers, Nautical Miles, US Nautical Miles
Include Attachments
When enabled, the reader will query for attachments associated with each feature, download them, and include them in a list attribute on each feature. Refer to the Format Attributes section for details about this attribute.
A warning is logged when this setting is enabled for a layer that does not support attachments.
Default: No
