Osservazioni

The Alter method updates any changes that have been made to the Check object's properties since the Check object was created or since the last Alter statement. The modifications are combined and sent to the instance of SQL Server in a single network trip.

[!NOTA]

For check constraints based on the UserDefinedTableType object this method generates an exception because user-defined data types cannot be modified.
