用法
Dim instance As SqlGeography
Dim returnValue As SqlBoolean
returnValue = instance.STIsEmpty()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public SqlBoolean STIsEmpty()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:
SqlBoolean STIsEmpty()
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
member STIsEmpty : unit -> SqlBoolean
public function STIsEmpty() : SqlBoolean
返回值
