删除所有文件和文件组示例

Question

这是一个简单的文件组，

USE master
GO
ALTER DATABASE AdventureWorks2012
ADD FILEGROUP Test1FG1;
GO
ALTER DATABASE AdventureWorks2012 
ADD FILE 
(
    NAME = test1dat3,
    FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\t1dat3.ndf',
    SIZE = 5MB,
    MAXSIZE = 100MB,
    FILEGROWTH = 5MB
),
(
    NAME = test1dat4,
    FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\t1dat4.ndf',
    SIZE = 5MB,
    MAXSIZE = 100MB,
    FILEGROWTH = 5MB
)
TO FILEGROUP Test1FG1;
GO

在此我要删除与Test1FG1组和Test1FG1组相关的所有文件。 怎么办？
