Geography 属性

The geography data type represents data in a round-earth coordinate system. The SQL Server geography data type stores ellipsoidal (round-earth) data, such as GPS latitude and longitude coordinates.

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

语法

声明
Public Shared ReadOnly Property Geography As DataType
    Get
用法
Dim value As DataType

value = DataType.Geography

public static DataType Geography { get; }

public:
static property DataType^ Geography {
    DataType^ get ();
}

static member Geography : DataType

static function get Geography () : DataType

属性值

类型：Microsoft.SqlServer.Management.Smo. . :: . .DataType
A DataType object value that specifies a Geography definition in the data type.

注释

The geography data type is predefined and available in each database. You can create table columns of type geography and operate on geography data just like you would use other system-supplied types.

示例

Visual Basic

Dim dt As DataType
dt = New DataType(SqlDataType.Geography)

PowerShell

$dt = new-object Microsoft.SqlServer.Management.Smo.DataType([Microsoft.SqlServer.Management.Smo.SqlDataType]::Geography)
