public DataTable EnumLocks(
	int processId
)

Parameters

A DataTable object value that contains a list of locks held on the database and information about the type and location of the locks. The table describes the different columns of the returned DataTable.

Column

Data type

The name of the database on which the lock is held.

Table

The name of the table on which the lock is held. This field contains a value only if the lock is held on a table.

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

VB

'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]
   }
}
