Parámetros

• other
  Tipo: Microsoft.SqlServer.Types.SqlGeometry
  The SqlGeometry instance from which to measure the distance between the instance on which STDistance is invoked. If other is an empty set, STDistance returns null.

Valor devuelto

Tipo: System.Data.SqlTypes.SqlDouble
A SqlDouble value that represents the shortest distance between a point in the calling SqlGeometry and a point in the specified SqlGeometry.

Comentarios

STDistance always returns null if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
