A review of many TSQL mistakes I see over and over at clients! This is a 100%-demo session, with the bad AND good code presented. I GUARANTEE that you will find things here that help you be MUCH better at interacting with SQL Server!!
Great database performance starts with great database design.
Isolation levels are one of the most complex subjects inside SQL Server and at the same time - one of the most important one. In this session we will take a look at all of them and see how they work behind the scenes.
Many customers are looking toward Cloud technologies to reduce operational and capital expenditures. A popular choices today for SQL Server customers is to deploy in the Microsoft Azure Virtual Machine environment. Come to this session and learn how
Data warehouse designers often ignore the specific needs of an OLAP database. In this session, John will outline the best ways to optimise your relational database to support your multidimensional OLAP cubes
This will be a deep dive into how the optimizer makes its decisions to give you a plan, the things that can go wrong and how you can have influence over these choices.
Many triggers are inefficient and violate best practices, but it doesn't have to be this way. Join this session and learn how to improve your triggers and keep them off the list of potential scapegoats for your SQL Server performance woes.
This session present key tools, methodology and approach for troubleshooting SQL Server. Performance and availability of the database engine has a direct impact on user experience of applications.
In this session we'll dig into the internal structures of indexes. We will explore the differences between clustered and non-clustered indexes, what's laid out within each page of the indexes.
Attend this session to learn how to take charge of optimization, expertly mold your query plans, and gain a new set of tools for eliminating bottlenecks in even your most complex problem queries.
Hekaton is the Greek word for 100 - the goal of In-Memory OLTP in SQL Server 2014 is to improve query performance up to 100 times. In this session we will look under the cover of Hekaton and the Multi Version Concurrency Control (MVCC) principles.
In this session, we will share some of the hard lessons learned from the first large deployments in Analysis Services Tabular.
In this session, we show how SSIS and HDInsight can work together, as well as how Hadoop jobs can be executed and how data can be transferred with SSIS between HDInsight, SQL Server, and other sources or destinations.
Still not sure of which is faster? Let us put this matter to rest once and for all. We will measure every single aspect of the execution of a stored procedure vs. its Ad-Hoc query counterpart, and only one will prevail!
This session will take a look at how parallel select into can be scaled to the nth degree in SQL Server such that all available hardware resources are utilised as fully as possible.
Learn how to assess query performance, ensure consistent and reliable query tuning, and avoid ten all-too-common performance killers in SELECT statements running on Microsoft SQL Server.
Microsoft has a famous whitepaper called "The Data Loading Performance Guide". On this session, we will turn the whitepaper into a presentation and see a few advanced ways to boost your data loading processes.
Indexing internals and how it impacts query performance.
In this session you'll learn all about SQL Server wait statistics. These are statistics the database engine stores about the resources it is waiting on. Armed with this information you as a SQL Server professional can make better informed decisions.
In this session, we'll explore SQL Server's plan cache, including techniques for discovering what plans are in cache, how often they've been run, and whether they contain any sub-optimal operators. Knowing what's happened is the first step in tuning.
In this humorous session I’ll be contesting many of the so called "best practices" in SQL Server and demonstrating counter arguments. Come along to see how so called "pillars" of design are starting to break down.
In this session we'll look at the common causes of bad execution plans and examine options for resolving the problem, short term and long term.
Learn how to use performance counters, report execution log data, and trace files to troubleshoot performance problems. Learn how to set up a monitoring solution to capture data and diagnose slow queries.
Information Workers and Data Analysts do “myth busting" on corporate performance and forecasts on regular basis. This session uncovers ways to take advantage of Power BI as Software as a Service (SaaS) for a "myth busting" lab you can try at home!
Sets are king when it comes to SQL Server, but sometimes you need to see data row by row. Window Functions help you get the best of both worlds. Learn when and where these functions can help you get what you need without compromising performance.
Attend this session and understand how, why, and when SQL Server uses statistics and how this new feature will help improve performance.
A deep dive into batch mode scalability with column store index and SQL 2014.
This 500 level session will focus on using undocumented statements and trace flags to get insight into how the query optimizer works and show you which operations it performs during query optimization.
We all know that ‘Indexing’ is KING when it comes to achieving high levels of performance in SQL Server. When Indexing also combines 2 of the Enterprise features: Partitioning & Compression
Join me for an hour of playing with different ETL patterns by using Clustered Columnstore Indexes. Using different Hardware might lead you to different conclusions,and the size of the workload is always the paramount of your performance.Loading data first and then creating a Clustered Columnstore or creating Clustered Columnstore and than loading - join me to find the answers!
In this session I will talk about backup, integrity check, and index and statistics maintenance, and how you can use my maintenance solution (http://ola.hallengren.com) in an enterprise environment.
Join this session to make a deep dive into how SQL Server implements physical locking with lightweight synchronization objects like Latches and Spinlocks.
Learn more about use cases and limitations for buffer pool extension. We will also cover the performance gains it can bring to your environment.
This session will help DBAs to understand what changes they need to make in their performance and monitoring practices for virtualized database servers.
Once you've decided to move to Azure with any of your databases, you're going to need to know how they're performing, this session shows you.
Alberto will start with a simple query and he will perform on stage all the necessary steps to optimize it, showing you the tools ant the techniques used to identify the bottleneck and to fix the performance issues
Because there are always at least two sides of the performance coin, in this session aimed at .Net and SQL developers, we'll dive into the workings of the .Net SqlClient and give you insight into way more than just SqlCommand.ExecuteReader()
