Length Property

Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.

The Length property specifies the maximum number of characters or bytes accepted by the referenced column or user-defined data type.

Osservazioni

For SQL Distributed Management Objects (SQL-DMO) objects referencing columns and user-defined data types defined on character data types, such as char and nchar, interpret the Length property as a number of characters. For objects referencing columns and user-defined data types defined on binary data types, such as varbinary, interpret the Length property as a number of bytes.
