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

returnValue = instance.STUnion(other)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeography STUnion(
    SqlGeography other
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeography^ STUnion(
    SqlGeography^ other
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STUnion : 
        other:SqlGeography -> SqlGeography 

public function STUnion(
    other : SqlGeography
) : SqlGeography

参数
