从.bak文件还原时动态获取数据库逻辑名称

Question

I am trying to create a python script that will dynamically restore databases from .bak files. Running the query

RESTORE DATABASE db_name FROM DISK = '\\path\to\db\db_name.bak' WITH REPLACE

works great if the original database name doesn't exist, however since there is multiple servers and often duplicate names this is not always the case.

In the case that the .mdf name contained in the .bak file does exist, the WITH MOVE syntax is useful as shown below

RESTORE DATABASE db_name 
  FROM DISK = '\\path\to\db\db_name.bak'
  WITH 
    MOVE 'Logical_name' TO '\\somepath\...\MyDB.mdf'

Unfortunately, this requires knowledge of the logical name before the query is run and is therefore not very useful for a general purpose script. Is there any way to get the logical name and populate it dynamically to make this more general purpose?
