无法删除SQL文件表

Question

我们在删除SQL文件表时遇到问题。每当我跑

select * from <MY SQL FILE TABLE> 

我收到此错误信息

A transport-level error has occurred when receiving results from the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

当我看到sp_readerrorlog，我看到这条消息

SQL Server internal error. FILESTREAM manager cannot continue with current command.

当我运行此查询

ALTER DATABASE XXX 
REMOVE FILEGROUP FStream1 

我收到这条消息：

The filegroup 'FStream1' cannot be removed because it is not empty.

我试图删除SQL文件表

drop table `SQLFiletable_bck` 

，但我得到这个错误：

The FILESTREAM filegroup 'FileStreamGroup1' has no files assigned to it. FILESTREAM data cannot be populated on this filegroup until a file is added.

然后我尝试这个选项

ALTER TABLE SQLFiletable_bck 
SET (FILESTREAM_ON = "NULL") 

，但我得到这个错误

Cannot drop FILESTREAM filegroup or partition scheme since table 'SQLFiletable_bck ' has FILESTREAM columns.

我无法删除SQL文件表

谁能告诉我什么办法强行清理的FileStream和SQL Server 2012中文件组？

为了解决

ALTER TABLE TableName SET (FILESTREAM_ON = "NULL") 

你必须放弃使用FILESTREAM列（S）。为了能够做到这一点，您可能不得不放弃一些限制：

ALTER TABLE TableName DROP CONSTRAINT DF_TableName_ColumnName; 
ALTER TABLE TableName DROP COLUMN ColumnName; 
ALTER TABLE TableName SET (filestream_on = "NULL"); 
ALTER DATABASE DatabaseName REMOVE FILE 'DatabaseFileName'); 
ALTER DATABASE DatabaseName REMOVE FILEGROUP "FilegroupName";
