UnloadODSDLL Method

  • [アーティクル]

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。新規の開発作業ではこの機能を使用しないようにし、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ことを検討してください。

The UnloadODSDLL method frees a dynamic-link library (DLL) loaded into Microsoft SQL Server memory.

構文

object
.UnloadODSDLL(
DLLName
)

Parts

  • object
    Expression that evaluates to an object in the Applies To list.
  • DLLName
    String that identifies a DLL loaded by Open Data Services by name.

Prototype (C/C++)

HRESULT UnloadODSDLL(
SQLDMO_LPCSTR szDLLName);

解説

SQL Server implements a call to a function exported from a DLL as an extended stored procedure. When a SQL Server process calls the extended stored procedure, SQL Server Open Data Services loads the DLL and locates the function entry point. By default, the DLL remains loaded until the SQL Server service shuts down.

Use the UnloadODSDLL method to free a DLL implementing a SQL Server extended stored procedure when required. For example, when a Microsoft Windows operating system loads a DLL, the operating system file implementing the library is opened as shareable, read-only. An attempt to update the file fails. Freeing the library allows installation of a new version of the library.
