语法

声明
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STIsValid As SqlBoolean
用法
Dim instance As SqlGeography 
Dim returnValue As SqlBoolean 

returnValue = instance.STIsValid()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlBoolean STIsValid()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlBoolean STIsValid()
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STIsValid : unit -> SqlBoolean
public function STIsValid() : SqlBoolean

返回值
