Actian Ingres Non-Spatial Feature Representation

Feature types correspond to the database table with the same name, and attributes correspond to columns of the same name.

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).

Attribute Name

Contents

ingres_type

The type of geometric entity stored within the feature. The valid values for the object model are listed below:

  • ingres_point
  • ingres_multipoint
  • ingres_linestring
  • ingres_multilinestring
  • ingres_polygon
  • ingres_multipolygon
  • ingres_geometrycollection
  • ingres_none

Note: Ingres Non-Spatial can read spatial features if they exist within the table being read. However, writing spatial features containing geometry into a table requires the Ingres Spatial writer.

No Geometries

ingres_type: ingres_none

Features with no geometries are tagged with this value when reading from Ingres.

Point

ingres_type: ingres_point

Features tagged with this value consist of a single point.

MultiPoint

ingres_type: ingres_multipoint

Features tagged with this value consist of a collection of points.

LineString

ingres_type: ingres_linestring

Features tagged with this value consist of a single line.

MultiLineString

ingres_type: ingres_multilinestring

Features tagged with this value consist of a collection of lines.

Polygon

ingres_type: ingres_polygon

Features tagged with this value consist of a linear polygon or donut.

MultiPolygon

ingres_type: ingres_multipolygon

Features tagged with this value consist of a collection of linear polygons and/or donuts.

GeometryCollection

ingres_type: ingres_geometrycollection

Features tagged with this value consist of a possibly heterogeneous aggregate.
