The spatial operator class ST_Geometry_Ops

An operator class defines operators, called strategy functions, that can use an index. The operator class that the HCL® OneDB® spatial data types require ST_Geometry_Ops.

Restriction: Do not use rtree_ops, the default R-tree operator class for the secondary access method.
The strategy functions for the ST_Geometry_Ops operator classes are:
  • ST_Contains()
  • ST_Crosses()
  • ST_Equals()
  • SE_EnvelopesIntersect()
  • ST_Intersects()
  • SE_Nearest()
  • SE_NearestBbox()
  • ST_Overlaps()
  • ST_Touches()
  • ST_Within()
