Infrastructure at your Service
Beginning of this year, it is good to clean up orphan users in SQL Server databases. Even if this practice must be done regularly throughout the year of course. 😉 During my cleaning day, a new case appears that I never had before and enjoy to share it with you. To find orphan database-users, I use this query: SELECT *FROM sys.database_principals a LEFT OUTER JOIN sys.server_principals b ON a.sid = b.sid WHERE b.sid IS NULL…
It has already been a few months that we are testing the next version of SQL Server: SQL Server 2019. I already blogged about a previous version of SQL Server supporting R and Python. With the new version of SQL Server 2019, Java will also be integrated. The Java runtime used is Zulu Open JRE and can be tested from the CTP3.2 of SQL Server 2019 Step 1: The installation Like a lot of people,…
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,…
It’s the 20th anniversary of the event and the keynote today was amazing (see the blog from Christophe) for different reasons but the more important is that is every time better people. Not only DBA’s but also people using their application connected to the database. Today, one of my focus will be the next version of SQL Server 2019 with the session of Bob Ward, Asad Khan & Amit Banerjee from Microsoft. I already tested…
After long hours of flights, Christophe Cosme and I finally arrived in Seattle at the SQL PASS Summit 2018. We picked up our badge and bag and now we are ready to begin… This first day for me started with the pre-conference about SQL Server Security with Denny Cherry. Many topics were discussed like: Network Designs (such as public IP vs. Private IP) Firewall configurations (such as Network Design between Public network, Internal network and…
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 let’s go ahead… This anti pattern may lead to a lot of duplicate keys and the customer wanted to get a picture of the…
Few weeks ago, I have a little issue when I try to drop a database-user without login Unfortunately, I do a little mistake at the beginning… I receive like every morning a report if all AD logins (computers, groups, users) registered on SQL server instances are in the AD with the useful command sp_validatelogins This report indicates that a computer name dbi\server_name$ was no more in the AD. I drop the login without problem and…
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. It’s also…
The GDRP (General Data Protection Regulation), voted in 2016, will be applied in the European Union soon (May 25, 2018). We heard a lot of this new directive. The goal is to improve the protection and confidentiality of personally identifiable information for every European citizen. Quid of Switzerland? Read the article of Gregory here. A personal data is information that identifies a natural person, directly or indirectly. It can be a name, a photograph, an…
This article is an additional article to my precedent about “SQL Server 2017: What’s happens with an interruption during a Resumable Online Index Rebuild?” The goal is to see after I suspend the rebuild, if I can run a traditional rebuild without the option RESUME. I start an index rebuild with the option Resumable: ALTER INDEX [NCI_dbo_Transaction] ON [dbo].[Transaction] REBUILD WITH (RESUMABLE = ON, ONLINE = ON) GO In a new query window,…
