Recipe for an awesome (free) SQL Server workstation

  1. Windows 10. Where we're going we don't need legacy software, but if you do, then download PowerShell 5.0 instead.

  2. SQL Server Management Studio 2016 and SQL Sentry Plan Explorer (Free). Don't forget that you should use Import-Module SqlServer instead of SQLPS for new work.

    Did you know SSMS now has a built-in plan comparison tool? But SSMS also has query plan display bugs so for the time being you'll still need both

  3. DBA Tools for PowerShell. If you're not coasting to retirement then start scripting now before it's too late, PowerShell automation is a disruptive technology. Oh, and come join the SQLCommunity (#DBATools, #General and #SQLHelp) on Slack.

SQL Server 2016 Master Data Services service accounts are broken

Warning: This is allegedly fixed in SQL 2016 RTM CU1. While I haven't tested that I can confirm that post-patch you'll get an MDS error requiring the service account be granted permission on an additional temp directory. I haven't documented that step below yet.

When setting up the web application for MDS you must specify an Active Directory service account to use for the application pool. What's hilarious about this is that this will break your MDS installation unless you also add that user as a local Administrator (!) or otherwise jump through hoops to identify what else is required (which I'm going to do below).

Revisiting SQL Server 2016 Master Data Services installation prerequisites

A year ago I wrote about installing MDS prerequisites using a PowerShell script but things have changed a little in SQL Server 2016 MDS and with ever more untested and ambiguous Microsoft documentation.

Using PowerShell to generate a bulk insert format file

There are some limitations with doing bulk inserts into SQL Server that can make it a pain. Some of the biggest ones:

  • You can't import if you have columns that change order in the source file.
  • You can't import if you have two columns with the same name in the source file.
  • If you use a non-standard delimiter like tab you may need a Schema.ini file with an entry for every file you're going to load up.

The main way around this is to do a proper bulk insert with a corresponding format file but you usually don't get provided those and they're difficult to create when they have to manage each of the above situations. Also they look extremely hard to make and understand.

SQL Server 2016 MDS upgrade errors

If you're doing an upgrade of the Master Data Services database to SQL 2016, there were some radical schema changes inside, and the upgrade may fail with an error:

SQL Server 2016 GDR update

Upon release of RTM one of the first issues indicated in the release notes was that a Visual C++ 2013 update was required before installation. Their recommendation to determine whether it's required is to manually check DLL versions but it's much more easily done through PowerShell.

SQL Server 2016 demonstrating a Bulk Insert crash dump

I sure hope you didn't jump feet first into the SQL 2016 RTM because it has a slew of problems. One of them is a crash dump on very simple bulk inserts. I've logged a Connect item so please vote for it.
