Advanced T-SQL Querying, Programming, and Tuning for SQL Server 2012/08/05
Monday, October 15, 2012 at 9:00 AM - Friday, October 19, 2012 at 5:00 PM (EDT)
New York, NY
This course was developed by Itzik Ben-Gan, a mentor and one of the founders of SolidQ, Microsoft MVP, author of several books about T-SQL, a columnist in SQL Server Magazine, and a regular speaker at SQL Server related events.
This course focuses on writing and tuning queries and programming with T-SQL in SQL Server 2005, 2008, and 2012. In this course you will learn the details and capabilities of T-SQL in the following areas: Logical Query Processing; Query Tuning; Subqueries, Window Ranking and Offset Functions, Joins and Set Operations; Aggregating and Pivoting Data; Window Aggregate Functions; TOP, OFFSET-FETCH, and APPLY; Data Modification; Working with Date and Time; Programmable Objects (Dynamic SQL, Views, User Defined Functions, Stored Procedures, Triggers, Transactions and Concurrency, Exception Handling); Graphs, Trees, and Hierarchies.
During the course, you will learn how to use T-SQL to solve practical problems such as: Relational Division, Ranking and Offsets, Missing and Existing Values (Gaps and Island), Separating Elements, Running Totals, Pivoting and Unpivoting, Custom Aggregations, Dynamic Analysis of Grouping Sets, TOP and OFFSET-FETCH Problems, Top N Per Group, Paging, Aggregate over Columns, Data De-Duplication, Handling Sequences, Treatment of Temporal Intervals (Overlaps, Max Concurrent, Packing), Dynamic Filtering, and more.
Furthermore, you will learn how to tune your queries; how to develop efficient routines including user-defined functions, stored procedures, and triggers; work in multi-user environments with transactions and isolation levels; and use dynamic SQL securely and efficiently.
You will also learn how to maintain and query hierarchical data. You will learn what graphs, trees, and hierarchies are; the common requests against graphs; and how to write T-SQL code to handle those requests. Several different solutions will be presented including: enumerated paths, nested sets, nested iterations using recursive queries, and the HIERARCHYID datatype.
The course provides a dedicated module focusing on query tuning. The module covers internals and index tuning, index access methods, temporary tables, set vs. cursors, and query tuning using query revisions. Moreover, query tuning is at the heart of this course and is incorporated throughout the different modules.
With each querying/programming problem, the discussions will revolve around logical aspects, set-based vs. procedural programming, and optimization of the solutions.Prerequisite: At least one year of T-SQL querying and programming experience in SQL Server
