BaseType 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 BaseType property exposes the system data type from which a user-defined data type has been derived.

Sintassi

object.BaseType [= value]

Parts

• object
  An expression that evaluates to an object in the Applies To list

• value
  A text string that identifies a Microsoft SQL Server system data type

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetBaseType(SQLDMO_LPBSTR pRetVal);
HRESULT SetBaseType(SQLDMO_LPCSTR NewValue);

[!NOTA]

SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference by using SysFreeString.

Osservazioni

The BaseType property is only modifiable before the UserDefinedDatatypeobject has been added to the UserDefinedDatatypes collection of a Database object. After the object is added to the collection and the user-defined data type is created on an instance of SQL Server, the property is read-only.
