BaseType Property

この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。 新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。

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

構文

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);
注意注意

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.

説明

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.
