'Utilisation
Dim instance As SqlGeometry

Paramètres

• other
  Type : 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.

Valeur de retour

Type : 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.

Notes

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