Presenter: John Flannery
Topic: Advanced Transactional Replication
We will cover several advanced topics in Transactional Replication including how to make a ddl change to one table in the publication without reinitializing the publication; how to make a ddl change to a table without having to snapshot; creating replicated tables on file systems other than Primary – including partitioned file systems; and bidirectional replication. And hint – we will be leaving the wizard in Redmond!! Bring a copy of SQL 2012 Developers Edition with AdventureWorks2012 if you want to play along.

Topic: The PowerShell Database Cookbook: Best Recipes
Downloads: Presentation Bundle
Maybe you’ve heard about all the great features of PowerShell, Windows scripting language, but thought, Ok, so how do I actually put PowerShell to use? In this presentation, Bryan will walk you through some ready to use PowerShell scripts while explaining the PowerShell language and integrated development environment (IDE). We will also discuss the best places to use PowerShell and when another tool is a better choice. So whether you’re a PowerShell newbie or experienced with the language, you’ll come away with new knowledge and some handy utilities. And if you’re asking yourself, what is PowerShell, you definitely need to attend this presentation.

Topic: SSIS Design Patterns for Better Performance
These days ETL developers face two common problems:
1: They are managing more and more ETL processes that have to complete in a shorter time window, and
2: their data is continuously growing. Today, more and more data has to be extracted from multiple sources, transformed, and loaded into its intended destination faster than ever before. SQL Server Integration Services is a robust product with lots of different options to choose when building an ETL package. Of course speedy hardware helps when it comes to performance, but have you ever wondered how the decisions you make when developing a package can affect the package’s performance? Come to this session to explore how SSIS handles memory, and have a better understanding of how certain tasks and transformations can affect your package’s performance.
Matt has 15 years of experience in the Information Technology field with a focus on software development and database administration. For the past ten years, he has worked extensively with Microsoft SQL Server and the .NET framework.
He has a Bachelors Degree from Bryant University with a concentration in Computer Information Systems, and also holds the Microsoft Certified Information Technology Professional (MCITP) Certification in Database Administration.

Topic: How isolated are your sessions?
Downloads: Available on CraftyDBA.com
Have you ever executed a TSQL program that crashed due to an integrity error?
Upon inspecting the job history, the error code states you have duplicate key values.
However; re-running the job does not reproduce the error. You probably had an transaction isolation level issue without knowing it.
I will be covering the following topics in this presentation:
- Maintaining the ACID quality of transactions
- How SQL Server implements transaction durability?
- System versus User transactions
- Transaction basics
- Exploring the various transaction modes
- Exclusive versus Shared locks
- Blocking versus Deadlocks
- How to detect them with my free code
- How Isolation levels affect transaction behavior
- What is a dirty read versus a phantom read?
At the end of the presentation, you will know how to fix the above scenario by changing the isolation level.
John has over twenty years of IT experience including a Masters degree in Computer Science from the University of Rhode Island with concentrations
in database technologies and programming languages. He also has Microsoft Certificates for Database Administration (MCDBA) and System Administration (MCSA).

leader for Southern New England SQL Server Users Group.

Topic: Taking BI to the Next Level: Collaboration
Self-service BI is usually an independent activity. But when individuals discover interesting information that they want to share, they need a centralized location to do that. When people work together, new insights are possible, and that’s what collaboration is all about. As more people see the benefits of the solution, they become more likely to use it. As individual products, SQL Server 2008 R2, SharePoint 2010, and Excel 2010 expand your options for enabling BI in your organization, but collectively they create a solid platform for collaborative BI. Knowing which tool to use for which job can be tricky. Come to this session to learn how to use these tools to foster collaboration.

Topic: Query Optimization – Specific Techniques to Make Queries Faster
Executing individual queries is the heart of what SQL Server does for us and many a hour is spent trying to optimize the performance of a single query. This presentation show that by examining query plans, specific techniques can be applied that transform slow queries into speedy ones. Using a series of examples Andy will demonstrate these techniques and show how the query plan and other tools point the way to a better solution.
Some of the techniques are:
- Optimize for specific conditions
- Managing parameter sniffing, auto parameterization and when to use the hints RECOMPILE, OPTIMIZE FOR or switch to dynamic SQL.
- Using a table of numbers
- Creating parallelism with CROSS APPLY
- Rewrite Functions for order of magnitude speedup
- Introduce a #temp table to get statistics and a better plan
- Adding redundant predicates
- Suppressing unnecessary statistics creation
Andy Novick is a SQL Server Developer in the Boston area with 25 years of database and application development experience. His consulting practice focuses on building applications, including software products that use SQL Server’s capabilities to the maximum. He has developed both OLTP and data warehouse databases with multi-terabytes scale. He has particular expertise in automating data management for such large databases.

Topic: What are you waiting for?
You’ve spent the afternoon sweating over your T-SQL query. You’ve wrung out all of the wrinkles. It’s deployed, it’s running… now its waiting. In SQL Server the most performant query can become a problem query if there aren’t any resources in the SQL Server for it to use. In this session, we’ll look at wait statistics and what they are. We’ll look into how they are accumulated and how they can be monitored. By the end of the session, you’ll be equipped with the tools needed to determine if there are resource issues in your environment and methods to start mitigating them.
