语法

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

returnValue = instance.BufferWithCurves(distance)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeography BufferWithCurves(
    double distance
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeography^ BufferWithCurves(
    double distance
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member BufferWithCurves : 
        distance:float -> SqlGeography

public function BufferWithCurves(
    distance : double
) : SqlGeography

参数

• distance
  类型：System.Double
  The maximum distance that points forming the buffer can be from the geography instance.

返回值

类型：Microsoft.SqlServer.Types.SqlGeography
The set of all points whose distance from the calling SqlGeography instance is less than or equal to distance.
