Returns an ST_Geometry type where the representation is one of the possible set of types in the following table, depending on the parameter types.

a — b Ø ST_Point ST_LineString, GeoSequence ST_Polygon ST_MultiPoint ST_MultiLineString ST_MultiPolygon
Ø Ø Ø Ø Ø Ø Ø Ø
ST_Point R01 R09 R09 R09 R09 R09 R09
ST_LineString, GeoSequence R02 R02 R08 R08 R02 R08 R08
ST_Polygon R03 R03 R03 R14 R14 R14 R14
ST_MultiPoint R04 R13 R13 R13 R13 R13 R13
ST_MultiLineString R05 R05 R08 R08 R05 R08 R08
ST_MultiPolygon R06 R06 R06 R14 R06 R05 R06
Where:
  • R01 = ST_Point

  • R02 = ST_LineString
  • R03 = ST_Polygon
  • R04 = ST_MultiPoint
  • R05 = ST_MultiLineString
  • R06 = ST_MultiPolygon
  • R08 = Ø, ST_LineString, ST_MultiLineString

  • R09 = Ø, ST_Point

  • R13 = Ø, ST_Point, ST_MultiPoint

  • R14 = Ø, ST_Polygon, ST_MultiPolygon

Teradata Database converts GeoSequence types that are involved in the ST_Difference method to ST_LineString values. Therefore, ST_Difference never returns a GeoSequence type.
