STDisjoint 方法

Determines whether the calling SqlGeography instance is spatially disjoint from the specified SqlGeography instance.

命名空间：  Microsoft.SqlServer.Types
程序集：  Microsoft.SqlServer.Types（在 Microsoft.SqlServer.Types.dll 中）

语法

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

returnValue = instance.STDisjoint(other)

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

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

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

public function STDisjoint(
    other : SqlGeography
) : SqlBoolean

参数

返回值

类型：System.Data.SqlTypes. . :: . .SqlBoolean
A SqlBoolean value that indicates whether the SqlGeography instance is spatially disjointed from the specified SqlGeography. If the instances are spatially disjointed, this method returns true. Otherwise, false.

注释

Two geography instances are disjoint if the intersection of their point sets is empty.

This method always returns null if the spatial reference IDs (SRIDs) of the SqlGeography instances do not match.
