ms138135.note(zh-cn,SQL.90).gif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 reference must release the reference using SysFreeString.

备注

The PhysicalName property is a string with a maximum of 260 characters.

Specify an operating system file using either drive and directory-based or Universal Naming Convention (UNC) file naming. For example, the strings "C:\Program Files\Microsoft SQL Server\Data\Northwnd.mdf" and "\\Seattle1\Program Files\Microsoft SQL Server\Data\Northwnd.mdf" are each valid for PhysicalName.

Applies To:

DBFile Object
