Groupby Free Sql Server Training

SQL injection is one of the most common ways that hackers gain access to your SQL server. Do you know how to harden your queries and protect your data from malicious users? This session will provide an overview of how SQL injection works and how to write injection-proof queries through a series of T-SQL demos. We’ll also take a look at why some commonly used techniques aren’t as secure as many people think. If you ever write or maintain dynamic SQL queries, or work with developers who do, then this session is for you.

You’ve just been given a server that is having problems and you need to diagnose it quickly. This session will take you through designing your own toolkit to help you quickly diagnose a wide array of problems. We will walk through scripts that will help you pinpoint various issues quickly and efficiently. This session will take you through; What’s on fire? – These scripts will help you diagnose what’s happening right now Specs – What hardware are you dealing with here (you’ll need to know this to make the appropriate decisions)? Settings – are the most important settings correct for your workload? Bottlenecks – We’ll see if there are any areas of the system that are throttling us. By the end of this session, you should have the knowledge of what you need to do in order to start on your own kit. This kit is designed to be your lifeline to fix servers quickly and get them working. All code we’ll go through is either provided as part of this presentation or are open source/community tools.

There are tools available from Microsoft, as well as from a number of third party vendors, to ease the process of integrating database unit testing into your development environments and your continuous delivery pipeline. This session isn't about any of those tools, but is an attempt to get back to basics - with the open source tSQLt framework - and address questions such as: Why is database unit testing important? Why is database unit testing difficult? What do I need to test? What do I not need to test? What does a "good" unit test look like? No particular experience of automated testing is required, we'll be talking about database testing "from the ground up". A good grasp of Transact-SQL constructs will be helpful in understanding the examples.

Do you work for an institution that fears its DBAs could go rogue on their production databases? Do you want to revoke continuous sysadmin permissions from your DBA team in an attempt to avoid being the next WikiLeak? Do you have concerns that the DBA team is querying sensitive databases? Then you need Uptight Database Security. Come to this session to learn how to deploy a configurable permission model that provides on-demand access to SQL Server databases. This model allows DBAs to do routine work without sysadmin, and elevate permissions to sysadmin only during production emergencies or disaster recovery scenarios. Attendees will leave this session with the fundamental knowledge and scripts to implement a low hassle solution that provides DBAs the minimum necessary access required to maintain a production database server.

Congratulations on your recent move into the world of SQL Server development! You've got a handle on the basics -- SELECT, INSERT, UPDATE, and DELETE -- but now what? How do you know what's important to learn next, and what's most likely a waste of time? In this session, we're going to answer these questions and more. You'll discover why set-based thinking is the foundation of SQL Server. You'll learn to use valuable T-SQL building blocks like window functions. I'll also share a handful of time-saving shortcuts that could save you an insane amount of typing, meaning you don't have to take another working lunch to clean up a poorly-formatted script. BUT WAIT, THERE'S MORE! In addition to learning new skills for today, you need to set yourself up for success next week, next month, and next year. That's why we'll also cover two things you can start doing right now to raise the incline of your career, and get you the recognition you'll deserve. Journey with me through stories, concepts, and live demos, and you wi

You’re a DBA or Developer, and you have a gut feeling that these simple queries with an egregious number of columns in the SELECT list are dragging your server down. You’re not quite sure why, or how to index for them. Worst of all, no one seems to be okay with you returning fewer columns. In this session, you’ll learn why and when queries like this are a problem, your indexing options, and even query tuning methods to make them much faster.

I’m going to look into the basics of how encryption works and then we’ll learn how we can go about writing our own encryption routines within SQL Server. When we’re happy that those routines are secure, we’ll look at ways that we can go about cracking those routines.  

SQL Server Failover Clustered Instances (FCI) and Availability Groups (AG) depend a lot on Windows Server Failover Clustering (WSFC). But when mission-critical databases go offline, bringing them back online could be a nerve-wracking experience. This session will look at understanding how the underlying WSFC platform works to help us maintain availability of our databases. This is for DBAs and systems administrators who are responsible for administering SQL Server FCIs and AGs but are not so comfortable with figuring out why the databases went offline and what they can do about it. We’ll walk thru the troubleshooting process that I follow to quickly identify and resolve SQL Server FCI and AG availability issues.

You’ve just been handed a SQL Server, and you need to make sure there aren’t any skeletons in the closet. What things should you check to make sure everything is healthy? In this presentation, we’ll run you through the checklist I use when I provide a health check to a customer. First, I check for any resume generating events (RGEs) like broken backups. Then I check for best practices like email alerts and MAXDOP settings. Finally, these checks turn into more a scuba diving expedition, where we look for things that seem off and dig deeper. You won’t walk away with a perfect strategy, but you’ll have an idea of how one data professional does it.

One of the most exciting new features of SQL Server 2016 is the integration of the R statistical programming language into the platform with the brand-new SQL Server R Services. In this introductory session we’ll briefly introduce the R language and then look at how to install and administer SQL Server R Services. We’ll start to demonstrate the power of R by showing you how to create and run simple R scripts from within T-SQL. We’ll then discuss some of the powerful open source packages that are available to aid your data analyses. Finally, we’ll go through some examples of how to use R to integrate data analytical methods in real-world situations, and wow your customers with the power of statistics!

T-SQL can help solve many problems you are faced with at your job. Each problem can have many solutions, but not every solution is simple to write, understand and maintain, and not every solution is good in terms of performance. In this session, we will look at real-world problems and solve them using T-SQL. We won’t settle for just A solution, but show elegant, simple solutions that will yield optimal performance.

In this session, I will talk about advantages of Query Store, features, configuration and query optimization using Query Store on SQL Server 2017. The session will also cover how one can monitor query performance, how Query Store gathers data and which are the best practices for using Query Store. During the session, there will be various demos.

Once data leaves your SQL Server, do you know what happens, or is the world of networking a black box to you? Would you like to know how data is packaged up and transmitted to other systems, and what to do when things go wrong? Are you tired of being frustrated with the network team? In this session, we introduce how data moves between systems on networks, then look at TCP/IP internals. We’ll discuss real-world scenarios showing you how your network’s performance impacts the performance of your SQL Server and even your recovery objectives.

Based on the successful 500 Level talk at PASS 2016, this session will provide an internals view of how In-Memory OLTP works for SQL Server 2016 and 2017. Because this session is Advanced, it is intended for those that understand the basic fundamentals of In-Memory OLTP but want to learn how the “Hekaton” engine works behind the scenes to deliver the amazing 30x performance improvements seen for customers moving to In-Memory OLTP. This session will include a look behind the scenes at threads, data and index design, transactions and concurrency, logging, storage, and natively compiled procedures. I’m a big believer in visuals and demos so you will see plenty of that as I describe how the Hekaton engine is truly lock-free and latch-free. And of course since this is an advanced talk, the Windows Debugger will definitely make an appearance during the session. And since this will be an advanced level session, of course, the demonstration of the looking at the Hekaton engine with the debugger is a must.

Are you faced with complaints from users, poor performing code from developers, and regular requests to build reports? Do you uncover installation and configuration issues on your SQL Server instances? Have you ever thought that in dire times avoiding Worst Practices could be a good starting point? If the answer is “yes”, then this session is for you: together we will discover how not to torture a SQL Server instance and we will see how to avoid making choices that turn out to be not so smart in the long run. You are probably thinking: “Hey, wait, what about Best Practices?”. Sometimes Best Practices are not enough, especially for beginners, and it is not always clear what happens if we fail to follow them. Worst Practices can show the mistakes to avoid. I have made lots of mistakes throughout my career: come and learn from my mistakes! Circles in the SQL Server Hell: Design sins: Undernormalizers Generalizers Shaky Typers Anarchic Designers Inconsistent Baptists Development sins: Environment Pollutors Ove

Microsoft has introduced native capability to the database engine around masking sensitive data and restricting access at the row level. Allowing us new options for building more secure Data Platform solutions. However, it is important to understand the differences from our previous options in order to be able to gain the most benefit from these new technologies. Join me as we look in more detail at how we can engineer these features into our Data Platform solutions. Starting with identifying the problems they are trying to solve, through their core architecture and on to potential design patterns for their use. As with any security technology solution, there are a number of ways to use these features. However, as with all security features, there are gaps in coverage, using them effectively in a layered approach is vital. After this session, you will be in a position to start looking at whether your systems can benefit from these features. Along with how you can potentially start building functionality into

On this session, we follow the movement of data through batch and speed layers via Azure Data Lake Store & Analytics, Data Factory, SQL Datawarehouse and Streaming Analytics, before looking briefly at Azure Analysis Services with PowerBI. This is a largely theory-based session to prime you for the future.

It just works – performance and scale in SQL Server 2016 database engine and what is being added to in-market versions. This session will showcase several improvements in SQL Server, focusing on the latest enhancements that address some of the most common customer pain points the Database Engine, involving tempdb, new CE, memory management, T-SQL constructs as well as diagnostics for troubleshooting query plans, memory grants, and backup/restore. Understand these changes in performance and scale, and the new and improved diagnostics for faster troubleshooting and mitigation.

TSQL was voted best programming language in 2013, let’s explore why! In this session, we will look at what makes SQL such a fascinating language. We will do this by working through a few real-life development problems and common design challenges based on real questions asked on Ask.SQLServerCentral.com.

Once you have successfully configured Availability Groups, what comes next? In this session, we will go beyond setup and look at how to monitor your Availability Groups. We will define and cover important metrics and alerts you need to manage a database in an Availability Group. You will walk away from this session with tools you need to monitor your environment and know how to respond to alerts.
