MergeUi Update

Published 2015-11-13 by Kevin Feasel

Ed Elliott has a new update to his MergeUi tool:

The way MergeUi used to work was that it enumerated the schemas and tables in a project and let you create a merge statement in the post-deploy script. The problem with that is that you may want to have different versions of the table for different environments or you may want to put the merge in a different script and either reference it using :r imports or not reference it at all.

The new way it works is that instead of enumerating tables it now enumerates script files (pre, post, included, not included etc) and lets you choose which table to add whether or not the table has been added before.

I’ve not used this tool before, but it’s good to know that it’s available via Github.

Always Encrypted

Published 2015-11-13 by Kevin Feasel

Kenneth Nielsen takes a look at Always Encrypted:

The way Microsoft have implemented this always encrypted feature, is to let all the data in the tables be encrypted. The application that needs to look at data will have to use the new Enhanced ADO.net library, which will give your application the methods to de/encrypt data.

This way, the only way to insert data into a table, which contains encrypted columns, is to use parameterized insert statements from your application. It is not even possible to insert data from SQL Server Management Studio, if we try, the statement will fail.

This way we ensure that only the persons using the application will be looking at un-encrypted data, thus reducing the number of people with a direct access to sensitive data.

If you go down this route, it looks like the only method available for modifying data is going through ADO.NET, although that could change later.  My biggest concern here is how much of a performance hit—if any—systems will take.

Connect To Azure VM Via SSMS

Published 2015-11-13 by Kevin Feasel

Derik Hammer shows you how to connect to an Azure VM hosting SQL Server:

After you provision a Microsoft Azure VM with SQL Server there are a few more steps that you need to take to make remote connections. The procedure below starts with a fresh Azure VM provisioned and walks through the process of establishing a connection via SQL Server Management Studio, installed on an on-premises work station.

Note that this is Azure IaaS, not Azure SQL Database.

DBA Morning Checklist

Published 2015-11-13 by Kevin Feasel

Pieter Vanhove has published his Policy-Based Management-based DBA Morning Checklist and has some post-Summit additions:

Optimize for Ad Hoc Workloads

The policy is going to check if the server setting Optimize for Ad Hoc Workloads, is set to True. By default, this setting is set to False.
The optimize for ad hoc workloads option is used to improve the efficiency of the plan cache for workloads that contain many single use ad hoc batches. More information can be found on https://msdn.microsoft.com/en-us/library/cc645587.aspx

I don’t see any downside by enabling this setting.

Not many shops use PBM, so I’m happy to see Pieter contributing this to the general community.
