RelocateFiles 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 RelocateFiles property specifies database logical file names and operating system physical file names used to redirect database storage when a Microsoft SQL Server database is restored to a new physical location.
语法

A SQL Distributed Management Objects (SQL-DMO) multistring built as specified in Remarks.
Data Type

Modifiable
Read/write
Prototype (C/C++)
HRESULT GetRelocateFiles(SQLDMO_LPBSTR pRetVal);
HRESULT SetRelocateFiles(SQLDMO_LPCSTR NewValue);

---|
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. |
注释
When creating a string directing physical file relocation, build the string as the current logical name of the database file, then the new operating system file name. Repeat pairings of logical name and physical name until all files implementing the database are specified. For example:
oRestore.RelocateFiles = "[Northwind1]" + "," + "[D:\Data\North_1.mdf]" _
+ "," + "[Northwind2]" + "," + "[D:\Data\North_2.mdf]"
