Maximize your performance on the exam by learning how to: Create database objects Work with data Modify data Troubleshoot and optimize queries You also get an exam discount voucher—making this book an exceptional value and a great career investment. After reading this book, you will be able to create, modify, and delete databases, tables, and indexes.
You can practice querying the data and running complex analytics on it. You will also be able to add, delete, and modify procedures, user-defined functions, triggers, and views. You'll then learn how to use DDL statements to create, modify and delete tables and indexes. Successively, you'll learn XML and JSON data processing, and by the time you'll reach the end of this book, you will learn to program in SQL Server and various strategies to deploy your databases and programs.
Throughout the book, you'll learn through simple examples and straightforward explanations, diagrams, and numerous real-world use-cases. Readers with a basic understanding of programming would have an advantage.
Getting started 2. Tables 3. Index 4. DML 5. Built-In Functions - Part 1 6. Join, Apply, and Subquery 7. Built-In Functions - Part 2 8. Variables and Control Flow Statements Error Handling and Transaction Management Programmability Apply powerful window functions in T-SQL—and increase the performance and speed of your queries Optimize your queries—and obtain simple and elegant solutions to a variety of problems—using window functions in Transact-SQL.
Discover how to: Go beyond traditional query approaches to express set calculations more efficiently Delve into ordered set functions such as rank, distribution, and offset Implement hypothetical set and inverse distribution functions in standard SQL Use strategies for improving sequencing, paging, filtering, and pivoting Increase query speed using partitioning, ordering, and coverage indexing Apply new optimization iterators such as Window Spool Handle common issues such as running totals, intervals, medians, and gaps.
T-SQL is the foundation for business logic embedded in the database in the form of stored procedures and functions. Beginning T-SQL starts you on the path to mastering T-SQL, with an emphasis on best-practices and sound coding techniques leading to excellent performance. Important techniques such as windowing functions are covered to help write fast executing queries that solve real business problems.
A stand-out feature in this book is that most chapters end with a "Thinking About Performance" section. These sections cover aspects of query performance relative to the content just presented. They'll help you avoid beginner mistakes by knowing about and thinking about performance from Day 1. Imparts best practices for writing T-SQL Helps you avoid common errors Shows how to write scalable code for good performance.
Beginning Queries with SQL is a friendly and easily read guide to writing queries with the all-important — in the database world — SQL language. Write a customer review. If you like books and love to build cool products, we may be looking for you.
It has a heavy focus on the performance of the code and also goes into more advanced techniques. Set up a giveaway. Here is the email address to use: Review core SQL concepts and its mathematical roots Create tables and enforce data integrity Perform effective single-table queries by using the SELECT statement Query multiple tables by using joins, subqueries, table expressions, and set operators Use advanced query techniques such as window functions, pivoting, and grouping sets Insert, update, delete, and merge data Use transactions in a concurrent environment Get started with programmable objects-from variables and batches to user-defined functions, stored procedures, triggers, and dynamic SQL Want to Read saving….
Would you like to tell us about a lower price? August 26, at itzii Then the book covers more-advanced data-query topics such as window functions, pivoting, and grouping sets. Next, it walks you through core topics such as single-table queries, joins, subqueries, table expressions, and set operators. A proper understanding of table naming is important as queries become more involved and complex.
Table and column aliases are covered as well, which are names that you can provide as substitutes for canonical names that are often long and cumbersome. Aliases provide a level of insulation in your queries from changes to names in the tables and columns that are being queried.
