無法刪除SQL文件表

Question

我們在刪除SQL文件表時遇到問題。每當我跑

select * from <MY SQL FILE TABLE> 

我收到此錯誤信息

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.)

當我看到sp_readerrorlog，我看到這條消息

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

當我運行此查詢

ALTER DATABASE XXX 
REMOVE FILEGROUP FStream1 

我收到這條消息：

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

我試圖刪除SQL文件表

drop table `SQLFiletable_bck` 

，但我得到這個錯誤：

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

然後我嘗試這個選項

ALTER TABLE SQLFiletable_bck 
SET (FILESTREAM_ON = "NULL") 

，但我得到這個錯誤

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

我無法刪除SQL文件表

誰能告訴我什麼辦法強行清理的FileStream和SQL Server 2012中文件組？

爲了解決

ALTER TABLE TableName SET (FILESTREAM_ON = "NULL") 

你必須放棄使用FILESTREAM列（S）。爲了能夠做到這一點，您可能不得不放棄一些限制：

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";
