PrimaryFilePath Property

后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The PrimaryFilePath property returns the path and name of the operating system directory that contains the primary file for the referenced database.

Prototype (C/C++)

HRESULT GetPrimaryFilePath(SQLDMO_LPBSTR pRetVal);

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 using SysFreeString.

备注

Microsoft SQL Server implements database data storage in one or more OS files. One OS file is designated as the primary file containing database-specific system tables. The primary file can be identified using the PrimaryFile property of the DBFile object.
