매개 변수

• other
  유형: 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.

반환 값

유형: 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.

주의

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