UserDefinedAggregates 属性

表示 UserDefinedAggregate 对象的集合。每个 UserDefinedAggregate 对象都表示对数据库定义的一个用户定义的聚合。

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

语法

声明
<SfcObjectAttribute(SfcContainerRelationship.ObjectContainer, SfcContainerCardinality.ZeroToAny,  _
    GetType(UserDefinedAggregate))> _
Public ReadOnly Property UserDefinedAggregates As UserDefinedAggregateCollection
    Get
用法
Dim instance As Database
Dim value As UserDefinedAggregateCollection

value = instance.UserDefinedAggregates

[SfcObjectAttribute(SfcContainerRelationship.ObjectContainer, SfcContainerCardinality.ZeroToAny, 
    typeof(UserDefinedAggregate))]
public UserDefinedAggregateCollection UserDefinedAggregates { get; }

[SfcObjectAttribute(SfcContainerRelationship::ObjectContainer, SfcContainerCardinality::ZeroToAny, 
    typeof(UserDefinedAggregate))]
public:
property UserDefinedAggregateCollection^ UserDefinedAggregates {
    UserDefinedAggregateCollection^ get ();
}

[<SfcObjectAttribute(SfcContainerRelationship.ObjectContainer, SfcContainerCardinality.ZeroToAny, 
    typeof(UserDefinedAggregate))>]
member UserDefinedAggregates : UserDefinedAggregateCollection

function get UserDefinedAggregates () : UserDefinedAggregateCollection

属性值

类型：Microsoft.SqlServer.Management.Smo. . :: . .UserDefinedAggregateCollection
一个 UserDefinedAggregateCollection 对象，该对象表示对数据库定义的所有用户定义聚合。

注释

Specific user-defined aggregates can be referenced by using this collection by specifying the name of the user-defined aggregate. To add a new user-defined aggregate to the collection, call the user-defined aggregate constructor UserDefinedAggregate.

示例

VB

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")

'Display all the triggers in the database.
Dim tr As DatabaseDdlTrigger
For Each tr In db.Triggers
   Console.WriteLine(tr.Name)
Next

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")

Foreach ($tr in $db.Triggers)
{
   Write-Host $tr.Name
}
