数据库中不存在文件 - SQL Server快照

I am attempting to create a database snapshot with SQL Server 2008 R2 using the following T-SQL code.

我正在尝试使用以下T-SQL代码使用SQL Server 2008 R2创建数据库快照。

CREATE DATABASE SNAP_myDB_0900
ON
 (NAME = myDB, FILENAME = 'C:\myDB_0900.SNAP')
AS SNAPSHOT OF myDB

I get the following error:

我收到以下错误:

The file 'myDB' does not exist in database 'myDB'

数据库'myDB'中不存在'myDB'文件

This code works with other databases in the same instance but not this one. I have double checked the file name and it is correct.

此代码适用于同一实例中的其他数据库,但不适用于此实例。我已经仔细检查了文件名,这是正确的。

Why am I getting this error?

为什么我收到此错误?

Verify the database file name that you are trying to create the snapshot based off of:

根据以下内容验证您尝试创建快照的数据库文件名:

select name, physical_name
from myDB.sys.database_files;

The NAME you give you snapshot file(s) needs to match the source database file name.

您为快照文件提供的NAME需要与源数据库文件名匹配。

In other words, if myDB's data file has a name of datafile1, then you will have to use ... NAME = 'datafile1' ... when creating your snapshot.
