获取服务器上 FILESTREAM 数据的子文件夹的 SQL 查询：（
这些表仅在专用管理员连接 (DAC) 中使用）。
SELECT o.name AS [Table], cp.name AS [Column], r.rsguid AS [Rowset GUID], rs.colguid AS [Column GUID] FROM SYS.SYSROWSETS r CROSS APPLY sys.sysrscols rs JOIN sys.partitions p ON rs.rsid = p.partition_id JOIN sys.objects o ON o.object_id = p.object_id JOIN sys.syscolpars cp ON cp.colid = rs.rscolid WHERE rs.colguid 不是 NULL 并且 o.object_id = cp.id AND r.rsguid 不是 NULL 并且 r.rowsetid = rs.rsid AND o.name = 'DOCUMENT' 和 cp.name = 'DIGITAL_FILE'；
