By a customer, I must migrate a database from a domain to another. The goal is to keep the database-user permissions, take the new SID from the windows login of the new domain and change the database-user name. In my blog, I will do it with two dbiâs domains: – dbiservicech: The old domain – dbiservicecorp: The new domain I have two Windows groups dbiservicech\dbi-owner and dbiservicech\dbi-reader in my database test-dbi. I create two new…
As we moved to Teams at dbi and one of our customers, automating tasks was a strong need. One of the tasks that could be automated is the creation of tasks in Microsoft Planner which does not support recurring tasks. Every 4 weeks, we are patching the environment. For everyone awareness and follow up, we need to publish these dates in the planning. As the pace of these tasks is known, it is a bit…
MSSQL-CLI is a useful new command line tool. Not so new because this tool exist since 2018 but a little bit unknow. You find this tool on GitHub here.

Few days ago, a customer asks me if it is possible to move the history table to slower but cheaper storage. The question behind this is whether it is possible to create a history table on a separate filegroup and file. Few years ago, I write a serie of blogs about temporal table here. I will take the same example to try to set up a filegroup specific to a history table. In my sample,…

Few months ago, a customer asks me for finding in a column, how many rows exist with the same date & time and the delta between them. The column default value  is based on the function CURRENT_TIMESTAMP and used as key as well. This is obviously a very bad idea but letâs go ahead… This anti pattern may lead to a lot of duplicate keys and the customer wanted to get a picture of the…

Last month (April 24, 2018), the Service Pack 2 for SQL Server 2016 was released and distributed. This Service Pack has new DMVs, already available in SQL Server 2017 RTM. In this article, I will just write few words about 2 DMVs (sys.dm_db_log_stats & sys.dm_db_log_info) and a new column (modified_extent_page_count) in the DMV sys.dm_db_file_space_usage that I presented during our last event about SQL Server 2017. I think they are really helpful for DBA. Itâs also…
