DBCC CHECKDB Azure SQL Database

Who should be running DBCC CHECKDB for Azure SQL Database? Should it be Microsoft or should customers be scheduling it? All official information just tells you that you CAN run it (below shows the green tick) but still no clarity around the question.

Azure Robots – Index Performance Recommendation

They are watching me and my Azure SQL Database and recently I noticed a low impact performance recommendation was made. Naturally I became very interested. Within your database (when in the portal) under operations you may notice something similar to the below:

AD Authentication and Azure SQL Database

Setting up AD authentication with Azure SQL Database sounds simple, it is assuming you plan carefully. I did run into issues but once rectified it felt great using AD authentication in Azure rather than just SQL logins.

Azure – SQL Database Premium RS

Copying your SQL Database

If you have created a SQL Database in Azure (PaaS) and need to make a copy of it on the same server I will show you how via a quick method.

When connected to your master database execute the following: It creates SAP2 based on SAP.

CREATE DATABASE SAP2 AS COPY OF SAP
 

To track the progress you can use the following query.

SELECT * FROM sys.dm_database_copies
WHERE partner_database = 'SAP2'
 

as

Replication state 1 means seeding, this means that the SAP2 database has not yet completely synchronised with the original database. 0 means pending, which means that the copy is being prepared.

Once this has completed you can check sys.databases to confirm that the database has successful been created.

SELECT * FROM sys.databases
WHERE name = 'SAP2'
 

as1

If you really want you can query sys.dm_operation_status to see the operations that have been performed on a database. I would expect to see some sort of operation around copying on my original database.

SELECT * FROM sys.dm_operation_status   WHERE major_resource_id = 'SAP'
ORDER BY start_time DESC;
