How to return data use, index compression, and row information with PowerShell

December 6, 2017 by Timothy Smith

Background

We recently inherited a database environment where we’re facing significant data growth with limits on the sizes we can allow our databases to grow. Since we maintain multiple development, QA and production environments and these environments must be sized appropriately. We set a few standards about tables that exceed certain sizes – rows, data or both, or have certain growth patterns and our standards force compression at thresholds we set for our different environments (including using page, row, or clustered columnstore index compression) We’re looking for how we can get information about data and compression in tables and options we have so that we can quickly determine candidates that don’t currently match our best practices design we’ve set for our environments.

An overview of Python vs PowerShell for SQL Server Database Administration

November 2, 2017 by Prashanth Jayaram

Today, Microsoft claims that Linux runs like a First-Class citizen on Azure, .NET Core has been open-sourced, and has been ported over to Linux, taking PowerShell along. PowerShell runs really well on Ubuntu, CentOS, RedHat Linux, and even Mac OS X. There are Alpha builds available for a few other platforms as well, all available for exploitation under the MIT License on GitHub. “Manage anything, anywhere” is what Microsoft is offering to its customers. Keeping with that, we now have:

Monitoring SQL Server database status changes using T-SQL and PowerShell scripts

October 17, 2017 by Prashanth Jayaram

Monitoring a SQL Server database is a critical component of database administration. Ninety percent of the organizations expect the number of databases to increase over the next twelve months. An increase in data volumes can have negative effects on the availability of databases. Hence, SQL Server database monitoring is considered a critical responsibility of a database administrator. Organizations tend to spend a lot of their funds towards enterprise solutions. And due to the sensitive and growing nature of business and user needs, application availability is very important nowadays.

How to configure Always Encrypted in SQL Server 2016 using SSMS, PowerShell and T-SQL

October 2, 2017 by Prashanth Jayaram

In an era of remote storage and retrieval of data, including the cloud, data security plays a vital role, especially since it’s vulnerable during the transit. Situations like database backup or copy from or to the cloud, there is always a risk of data exposure to outside world lurking around one corner or the other. We have seen a noticeable surge in the technologies around protection and security of data from the world full of unsafe hands. Efforts are being made to protect data at a very granular level of the encryption hierarchy. Protection of business data cannot be stressed upon more.

How to connect to (and query) Power BI and Azure using PowerShell

September 13, 2017 by Craig Porteous

Power BI “as a whole” is a bit of a black box. If you’re like me and used to using SQL Server & its components; SSRS, SSAS etc. you have access to installation directories, Event logs, trace logs, error logs, chocolate logs? You can see full instances & their contents in one go, whether that be databases, reports or cubes. It gives you the control over & responsibility for performance & maintenance. Read more »

How to Capture Database(s) usage stats using sp_spaceused and PowerShell

September 11, 2017 by Prashanth Jayaram

Today’s businesses work with huge volumes of data. Sometimes, understanding the granularity of the data is helpful in data administration. Understanding the granularity poses unique challenges though and the database administrator needs to balance the key business and technical metrics of the environment. One of the key technical metrics is disk space estimation, which is vital to capacity planning and forecasting. The simplest way to get this information is by using the system stored procedure, called, sp_spaceused. The growth metrics can be captured periodically and stored in a central repository, a repository dedicated to helping with capacity planning and forecasting the disk requirements. This is a critical part of the day-to-day activities of a database administrator.

Multi-server Script to Find Orphaned Data Files using PowerShell

August 23, 2017 by Prashanth Jayaram

Having worked in busy dev-test environments, it isn’t uncommon to come across situations where someone detached a database from an SQL server, but forgot to reattach it, or drop it from the server. The next task we are then required to undertake, upon coming across such a situation, is to clean up the traces. This task can be complicated if the detached databases get deregistered from the SQL Server metadata catalog.

What is new in SSMS 17; PowerShell and DAX

August 21, 2017 by Daniel Calbimonte

Introduction

In earlier versions, SSMS was included in the SQL Server installer. Now it is a tool that is installed separately.

In this new article, we will emphasize PowerShell and DAX. PowerShell is handled in a different way than it was in SQL Server 2016. We will give you some tips to handle these differences. In the second part of the article, we will talk about DAX. If you do not have experience with DAX, we will give you an introduction to Multidimensional, Tabular databases and you will be able to understand the new features and run your first DAX query in the new SSMS 17.

Planning a SQL Server Backup and Restore strategy in a multi-server environment using PowerShell and T-SQL

August 15, 2017 by Prashanth Jayaram

Introduction

Database availability is critical to every enterprise and conversely, unavailability directly can create a severe negative impact to the business in today’s world. As database administrators, it is important that we ensure we take all possible steps to minimize data loss. While it is naïve to think that our databases are invincible because of all such precautions, we can always aim to bring the databases back into operation as quickly as possible by meeting the RPO and RTO. This way, the business is unaffected, and we also meet our SLAs.

Connecting PowerShell to SQL Server – Using a Different Account

January 24, 2017 by Shawn Melton

Introduction

In a previous article on Connecting PowerShell to SQL Server I went over how you use various methods in PowerShell to connect to SQL Server. In those examples though I only touched on using the current user that is running “PowerShell.exe”. In this article I want to pick up and go over how you would use the same methods, but as a different account. I will cover using both Windows Authentication (where supported) and SQL Login authentication.

How to administer SQL Server Reporting Services (SSRS) subscriptions using PowerShell

January 23, 2017 by Sifiso Ndlovu

In the article Report Subscription Changes in SQL Server Reporting Services 2016, I covered several changes to standard and data-driven subscriptions that were introduced in the release of SQL Server 2016. However all of those changes related to administering report subscriptions using a GUI (i.e. Report Manager Portal, SSRS Configuration Manager). The release of SQL Server Core, SQL Server on Linux and enhancements on Windows PowerShell, reinforces the growing shift by Microsoft to have SQL Server professionals adopt scripting as one of the ways to carry out their daily tasks. In this article we continue to explore SQL Server Reporting Services (SSRS) subscription feature by discussing some of the Windows PowerShell commands that can be utilised to administer report subscriptions.

Microsoft SQL Server Non-Contained Object Migration Deployment Procedure using Powershell

January 12, 2017 by Musab Umair

As DBAs, we all face a lot of challenges while performing the migration of SQL Server databases from one server to another or even the whole servers at some times. The Database Migration process is not always a simple Backup and Restore process so we might need a huge amount of effort if we have to migrate objects which are not included in the native backups for a specified database, these objects are called Non-Contained Objects.

PowerShell: Get a daily database status email

November 22, 2016 by Aamir Syed

The need for this script came about when I took a new job as a DBA. One of my responsibilities was to make sure all databases were available after the maintenance window which ran during the weekend. Rather than log into each database server and check that the databases were online, I had a script do the work for me and shoot me an email.

SQL backup reports with PowerShell

August 15, 2016 by Aamir Syed

Let me preface this post by saying that this was a process that evolved over time. It started as a simple sql statement that emailed me a csv file. From there the actual SQL code evolved to display cleaner results. When I learned what powershell could do, I spent some time learning it during my lunch breaks at work. Even when I implemented a powershell script for the first time, it still wasn’t a clean looking report, but it was still better than what we had prior. Even now there is room for improvement but I am happy with the results and hope that it can provide some help to other SQL DBA’s out there.

SSIS and PowerShell – Execute process task

April 11, 2016 by Shawn Melton

Introduction

SQL Server Integration Services (SSIS) and PowerShell (PS) together offer a plethora of opportunities, and some shortcuts when having to import, export, or at times moving data. I have come across packages that contain a Script Task with lines and lines of C# code that, done with PowerShell, could make maintaining that package much easier. Overall, the most common thing I see Script Task doing is accessing the file system or doing some manipulation on a file. One thing I hope that picks up speed in the BI world of SSIS is utilizing PowerShell for these type of actions. This is not to say one is better than the other as you should pick what is best in your eyes, but when I can do operations against the file system with a one-liner in PowerShell it is just easier to maintain that in the package. In this article I will go over how you can use the most common task utilized for executing PowerShell code in an SSIS package: Execute Process Task.

Connecting PowerShell to SQL Server

January 13, 2016 by Shawn Melton

Introduction

PowerShell (aka Posh or just PS) is becoming more and more of a tool for operational support and some deployment scenarios. If you need to pull or place data into SQL Server, PS can be a handy way of doing it in both one-off and automated work.

There are a number of ways to connect to SQL Server via PS. In this article I wanted to go over the options that are available to you. If you have used PS for any number of months or years, you know there tends to be multiple ways of performing a task. So it goes without saying if you are building out scripts to use in production to test, test, and test…then test it one more time.
