CHECKDB and Page Restoring from SSMS

Did you know that you can run DBCC CHECKDB (WITH PHYSICAL_ONLY) and issue page restores from SSMS (SQL Server Management Studio). I never, and I probably will never because I rather use TSQL however I have only just seen this ( yes it’s been around for a while ) and felt like blogging about it.

I clicked on restore > page.

I corrupted page 126 and look it knows about it!

Yes it’s in bad shape Level 24 severity.

SELECT * FROM [ZoraDB].[dbo].[people]

SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0xa154e798; actual: 0xa144e788). It occurred during a read of page (1:126) in database ID 11 at offset 0x000000000fc000 in file ‘C:\Program Files\Microsoft SQL Server\mssql12.MSSQLSERVER\MSSQL\DATA\ZoraDB.mdf’. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

So SSMS is so good it will restore for you and build the restore chain.

How cool is that?
