Параметры

• other
  Тип: Microsoft.SqlServer.Types.SqlGeometry
  Is another SqlGeometry instance to compare against the instance on which STRelate is invoked.

• intersectionPatternMatrix
  Тип: System.String
  A string that specifies the intersection model. This string must contain acceptable values for the DE-9IM pattern matrix device between the two SqlGeometry instances.

Возвращаемое значение

Тип: System.Data.SqlTypes.SqlBoolean
Returns true if a SqlGeometry instance is related to another SqlGeometry instance, where the relationship is defined by a Dimensionally Extended 9 Intersection Model (DE-9IM) pattern matrix value; otherwise, returns false.

Замечания

This method always returns nullпустая ссылка (Nothing в Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match. This method will throw an ArgumentException if the matrix is not well-formed.
