The Pause option on the SQL Server service account prevents new connections, but allows existing connections to continue operating.
When would you use this? Most likely during a patching or outage cycle to allow existing users to gracefully exit while preventing new connections.
In case you missed it, AUTOGROW_ALL_FILES was added in SQL Server 2016 and tempdb has this enabled by default.
Further info is mentioned here.
EXEC sp_MSforeachdb ' USE [?]; SELECT DB_NAME() AS database_name ,[name] ,type_desc ,CASE WHEN is_autogrow_all_files = 0 THEN ''no'' ELSE ''yes'' END AS is_autogrow_all_files FROM sys.filegroups';

In SQL Server Management Studio 17.0 the PowerShell module was moved into the PowerShell gallery.
This means that you may see the following:
When you go to https://www.powershellgallery.com/ you currently see:
I don’t know about you, but it suddenly seems that a simple tweak to SSMS has become a headache for DBAs.
Performing a search gives 4 results and it looks like the matteot_msft is the correct one. Having company package under a users name doesn’t sound like a good idea to me, possibly this should be a team account?
So how do you download it?
lol mind blown, KISS appears to have gone out the window :)
If you’ve made it this far and have an internet connection the supplied method is:
Save-Module -Name SqlServer -Path
Install-Module -Name SqlServer
Lets give it a try:
It’s now requesting NuGet provider version ‘220.127.116.11’ or newer
Once completed you’ll see the folder and files
For the next step, I received the following message which requested for -Force to be used:
Once completed, the SSMS error message no longer occurs
Yes from PowerShell 3.0 there is the ability to use the Tail parameter in Get-Content.
Details can be found here.
Say you wanted to look at a SQL 2016 default instance errorlog file based on a D drive you could use:
Get-Content "D:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Log\ERRORLOG" -Tail 10 –Wait
If you come across the following error when attempting to install SQL Server Mobile Report Publisher
you’ll likely find that the currently link doesn’t work
At this time the requirement can be found here. Note: After the install you may be requested for the server to be restarted. You don’t have to, but it’s a good idea to do so.
The install then should go smoothly.
Given that Visual Studio 2017 is now out, we’ll hopefully be seeing this legacy 2013 requirement removed.
A few years ago I did a blog on viewing sample rows in all used tables.
Here is another similar query which allows you to peek at the top 5 rows in each view.
SELECT 'SELECT TOP 5 ''[' + SCHEMA_NAME([schema_id]) + '].[' + [name] + ']'' AS view_name, * FROM [' + DB_NAME() + '].[' + SCHEMA_NAME([schema_id])+ '].[' + [name] + '] WITH (NOLOCK);' FROM sys.all_views ORDER BY [name];
SELECT 'SELECT TOP 5 ''[' + SCHEMA_NAME([schema_id]) + '].[' + [name] + ']'' AS view_name, * FROM [' + DB_NAME() + '].[' + SCHEMA_NAME([schema_id])+ '].[' + [name] + '];' FROM sys.all_views ORDER BY [name];
The installation process of SQL Server is continually evolving.
Recently the setup allowed tempdb file adjustments with a default of 4 files and the ability to grant the Perform Volume Maintenance Task privilege.
Such a focus on tempdb was a surprise to me as in the 13+ years I’ve worked with SQL Server (tackling literally tens of thousands of instances) there was only once when more than 1 data file was required. To put this in perspective, the SQL Server was accessed by all students at a large university and the tempdb GAM contention was obviously clear. Adding another single data file (2 in total) to this high spec server resolved the issue.
Adding additional tempdb files, to me is an advanced feature and should be carefully considered so as to not waste disk space, ensure even file growths, minimize complexity etc.
In my view it would have been more productive for Microsoft to have focused the setup on the following:
- set memory limits (this has to be done 100% of the time) and don’t stop with the engine, include SSAS and SSRS
- set max degree of parallelism (I believe the default of 0 is incorrect, rather it should be 1 as most instances are not dedicated to a hosting a single application due to licensing costs,consolidation etc)
- set backup compression (should be defaulted to 1)
- set optimize for ad hoc workloads (should be defaulted to 1)
- allow setting Perform Volume Maintenance Tasks (tick)
- allow setting Lock Pages in Memory
- allow enabling remote admin connections
- allow setting the listening port and adding the appropriate firewall entry (this would likely save thousands of can’t connect issues)
