Valeur de retour

Type : System.Data.DataTable
A DataTable object value that contains a list of open transactions that affect the database. The table describes the different columns of the returned DataTable.

Column	Data type	Description
Name	String	The name of the transaction.
TransactionID	String	The ID value that uniquely identifies the transaction. See sys.dm_tran_active_transactions (Transact-SQL).
BeginTime	DateTime	The date and time when the transaction started.
Spid	Int32	The session ID that uniquely identifies the session in which the transaction is running.
DatabaseName	String	The name of the database in which the transaction is running.
DatabaseID	Int32	The ID value of the database in which the transaction is running. See sys.databases (Transact-SQL).
DatabaseBeginTime	DateTime	The date and time when the database came online.
IsVersioned	Boolean	The Boolean value that specifies whether the transaction is a snapshot transaction and has a sequence number. See TransactionTypes enumeration class.

Exemples

The example runs a Server object enumeration method, but extracting the information from the DataTable object is the same for Database enumeration methods.

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Call the EnumCollations method and return collation information to DataTable variable.
Dim d As DataTable
'Select the returned data into an array of DataRow.
d = srv.EnumCollations
'Iterate through the rows and display collation details for the instance of SQL Server.
Dim r As DataRow
Dim c As DataColumn
For Each r In d.Rows
    Console.WriteLine("============================================")
    For Each c In r.Table.Columns
        Console.WriteLine(c.ColumnName + " = " + r(c).ToString)
    Next
Next

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")

$d = new-object System.Data.Datatable
$d = $srv.EnumCollations

Foreach ($r in $d.Rows)
{
   Write-Host "============================================"
   Foreach ($c in $d.Columns)
   {
      Write-Host $c.ColumnName "=" $r[$c]
   }
}
