With SQL Server 2016, I’m nicely surprised by the addition of IF EXISTS directly in the T-SQL command DROP. Before this new option, all queries are written with IF EXISTS (SELECT * FROM sys….) DROP object. I have quickly tested just for 2 drop commands(See List of available objects below): one for a table one for a column in a…
A customer asks me, what is the collation for System Center products? Do we have a general collation for all products? And what is the BP for Tempdb? And how work the licencing for SQL Server in System Center (is SQL Server included)??? I answer just “OK, OK, I understand, I wil check those points…” I search those information on…
For last week, the SQL Server 2016 Community Technology Preview 3.0 has been available with a lot of enhancements on new features. All info about CTP3 are on SQL Server Blog here. I wrote some weeks ago, a blog about JSON Support in SQL Server 2016: SQL Server 2016: native support for JSON With this new CTP version, JSON support…
This blog is a part of the series “SQL Server 2016 – Security: Dynamic Data Masking“. I remember you my different logins used to connect to AdventureWorks: sql login u1 with the db_owner role –> No masking sql login u2 with the db_datareader role –> masking The Data Types used are: xml, date, datetime and varbinary. I run this query…

After my first blog on Security with Row level Security, I test the second Security new feature in the next version of SQL Server: Dynamic Data Masking. I presented this new feature to my Oracle colleagues and I’m surprised that Oracle 12c has the same option known as Data Redaction. The principle is simple: for some users, data are masked…
In many blogs or forums, you can read that the answer is to use the option: WITH ESTIMATEONLY. With this option, you can easily have the space estimation needed to check the database in tempdb. But be careful, only since SQL Server 2014, this estimation has been good! See the PS from Paul Randal’s blog for this information, here But…
In all blogs that I read, the solution is just to change the retention period to a reasonable value. Yes, it is true but in some case you need to go deeper in the analysis… Like you, I changed the retention period, ran the cleanup but finally, I had always a big database… Why, Why, Why? My first step for…
Why “also” in my title? On 29 August, my colleague Daniel Westermann wrote an article about Row Level Security in the next version of PostgreSQL. Row Level Security called also RLS is a new feature in SQL Server 2016 and of course in SQL Azure. This new security in SQL Server returns only rows that the user has permission to…
A couple of days ago, I was involved in a project about implementing availability groups with SQL Server 2014. My customer wanted to isolate the replication traffic from the public network. The idea behind was to get a better control of the network bandwidth as well as to be sure that the replication can be done without any latency issues…
Maintenance & Metadata My last chapter is about the maintenance backup/restore, index rebuild/reorg., etc. and the Metadata. I divide my article into 4 parts to be clearer and easier to read: Part I – Principle & Creation Part II – INSERT, UPDATE & DELETE commands Part III – SELECT command Part IV – Maintenance & Metadata SQL Server version/built used…
