Property Value

Type: System.Int32
An Int32 value that specifies the maximum number of processors to use in a parallel plan execution.

Examples

The following code example shows how to specify the maximum number of processors used for parallel plan executions that include the defined table.

Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2008R2"];

Table tb = new Table(db, "Test Table");
Column col1 = new Column(tb, "Name", DataType.NChar(50));
Column col2 = new Column(tb, "ID", DataType.Int);

tb.Columns.Add(col1); 
tb.Columns.Add(col2); 
tb.MaximumDegreeOfParallelism = 3;
tb.Create();

Console.WriteLine("The maximum number of processors that can be used in parallel plan execution for this table is " + tb.MaximumDegreeOfParallelism);

Powershell

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

#Create the Table
$tb = new-object Microsoft.SqlServer.Management.Smo.Table($db, "Tesghjt Table")
$col1 = new-object Microsoft.SqlServer.Management.Smo.Column($tb, "Name", [Microsoft.SqlServer.Management.Smo.DataType]::NChar(50))
$col2 = new-object Microsoft.SqlServer.Management.Smo.Column($tb, "ID", [Microsoft.SqlServer.Management.Smo.DataType]::Int)
$tb.Columns.Add($col1)
$tb.Columns.Add($col2)
$tb.MaximumDegreeOfParallelism = 3
$tb.Create()

Write-Host "The maximum number of processors that can be used in parallel plan execution for this table is" 
            $tb.MaximumDegreeofParallelism
