Notes

This property specifies whether any comparison to a null value equates to a NULL value. For, a SELECT statement that uses WHERE column_name <> NULL returns zero rows even if there are non-null values in column_name.

Exemples

The following code example shows how to declare a new table on the specified database, with the specified name.

Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2012"];

Table tb = new Table(db, "Test Table");
tb.AnsiNullsStatus = true;

Powershell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2012")

#Define the Table
$tb = new-object Microsoft.SqlServer.Management.Smo.Table($db, "Test Table")
$tb.AnsiNullsStatus = $TRUE
