Note from MSDN: DBCC CHECKDB is supported on databases that contain memory-optimized tables, but validation only occurs on disk-Based tables. However, as part of database backup and recovery, a CHECKSUM validation is done for files in memory-optimized filegroups. Since DBCC repair options are not available for memory-optimized tables, you must back up your databases regularly and test the backups. If data integrity issues occur in a memory-optimized table, you must restore from the last known good backup.

Here are few relevant blog posts about DBCC.

  • Yes this is a neat trick, however, sp_msforeachdb is going to be deprecated in a future release of SQL and Microsoft doesn’t recommend using it in scripts.
