property UserDefinedAggregateCollection^ UserDefinedAggregates {
    UserDefinedAggregateCollection^ get ();
}
[<SfcObjectAttribute(SfcContainerRelationship.ObjectContainer, SfcContainerCardinality.ZeroToAny,

属性值

类型:Microsoft.SqlServer.Management.Smo.UserDefinedAggregateCollection
A UserDefinedAggregateCollection object that represents all the user-defined aggregates defined on the database.

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 AdventureWorks2012 database.
Dim db As Database
db = srv.Databases("AdventureWorks2012")

'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("AdventureWorks2012")

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