Comentarios

This method is functionally equivalent to the Transact-SQL CHECK IDENT statement. An error will be thrown if this method is called on a table with no Identifier columns.

Ejemplos

The following code example shows how to check and display the identity value of a table.

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

Table tb = new Table(db, "Test Table");
Column col1 = new Column(tb, "TableIdentifier", DataType.Int);
col1.Identity = true;
tb.Columns.Add(col1); 

foreach (String s in tb.CheckIdentityValue())
{
   Console.WriteLine(s);
}

Powershell

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

$tb = new-object Microsoft.SqlServer.Management.Smo.Table($db, "Test Table")
$col1 = new-object Microsoft.SqlServer.Management.Smo.Column($tb, "TableIdentifier", [Microsoft.SqlServer.Management.Smo.DataType]::Int)
$col1.Identity = $TRUE
$tb.Columns.Add($col1)

Write-Host $tb.CheckIdentityValue()
