Query Some Files I have a SQL Server 2019 database that has two filegroups, PRIMARY and ARCHIVE. I take one file offline with this code: ALTER DATABASE FGTest MODIFY FILE (NAME = N'FGArchive1', OFFLINE) GOI had created two tables with this code: CREATE TABLE [dbo].[MyTable]( [myid] [int] NULL, [mychar] [varchar](200) NULL ) ON [PRIMARY] GO CREATE TABLE [dbo].[MyTable2]( [myid] [int] NULL, [mychar] [varchar](200) NULL ) ON [Archive] GOI then run this code: SELECT top 10 * FROM dbo.MyTable2 AS mtWhat happens? Answer: I get an error that the query processor cannot produce a plan Explanation: I get an error that that query processor cannot produce a plan as the filegroup is not online.
