The Microsoft data platform is evolving The third day began with the Keynote help by Rohan Kumar the Corporate Vice President of Azure Data by Microsoft The main message was “Hybrid data platform is the way for the future” and Microsoft is working in this direction. The use of AI and analytic to transform the customer business is also a key driver for the Microsoft data platform, which is building to enable this easily. Rohan…
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…
writeThis is a second write-up about SQL Server 2019 CTP2.0 and availability group new features. This time the interesting one is about READRWRITE redirection capabilities. A couple of months ago, I wrote about SQL Server 2017 and new read-scale capabilities and listener management challenges regarding the operating system. Indeed, there are some scenarios where including listener will not as easy as we did with common ones on the top of Windows operation system. A list of…
Few weeks ago, my colleagues and me discussed availability groups and network considerations for one of our customers including disabling SQL Browser service and shared memory protocol. The point was disabling both features may lead to unexpected behaviors when creating availability groups. Let’s start with the SQL Browser service. It is not uncommon to disable this service at customer shops and to use directly SQL Server listen ports instead. But if you go trough the…
A couple of weeks ago, Microsoft announced the first public CTP version of next SQL Server version (CTP2). It is not a surprise, the SQL Server vNext becomes SQL Server 2019 and there are a plenty of enhancements as well as new features to discover. But for now, let’s start with likely one of my favorites: availability groups on Kurbernetes (aka K8s). As far I may see from customers and hear from my colleagues as well,…
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…
The release of Docker for Windows Stable version 18.06..0-ce-win70 comes with some great new features I looked for a while including the K8s support! That’s a pretty good news because this support has existed on Edge channel since the beginning of this year but no chance to install a beta version on my laptop from my side. So, we get now a good opportunity to test locally our SQL Server image with a K8s single…
Let’s start the story from the beginning with some funny testing I tried to perform with SQL Server on Linux a couple of months ago. At that time, I wanted to get some pictures of syscalls from SQL Server as I already did in a past on Windows side with sysinternal tools as procmon and stack traces. On Linux strace is probably one of the best counterparts. Firstly, please note this blog is just from…

Le prochain SQL Saturday Paris arrive bientôt et l’agenda a été publié sur Twitter par le @GUSS Cette année, un savant mélange de speakers francophones et internationaux, un plus pour les participants … Un rapide coup d’œil à l’agenda – si on se focalise sur la partie moteur SQL Server – montre également qu’une bonne…
