Public Function STStartPoint As SqlGeography
用法
Dim instance As SqlGeography
Dim returnValue As SqlGeography

returnValue = instance.STStartPoint()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public SqlGeography STStartPoint()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:
SqlGeography^ STStartPoint()

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
member STStartPoint : unit -> SqlGeography 

public function STStartPoint() : SqlGeography

返回值
