BaseType Property

Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.

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

Syntax

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);

Hinweis
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.

Hinweise

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.
