Understanding SQL Data Management and Querying
In Exam Ref 70-761 Querying Data with Transact-SQL by Itzik Ben-Gan, we delve into the world of managing and querying data using Structured Query Language (SQL). The book begins by introducing the SQL Server platform and Transact-SQL language, which is the primary focus of the exam. It explains the basic concepts of databases, tables, and data types, and the tools and techniques used to manage and query data efficiently.
The book then moves on to explore the fundamental aspects of querying data, starting with simple SELECT statements and gradually progressing to more complex queries. It covers filtering and sorting data, using built-in functions, and combining data from multiple tables using joins. It also discusses the use of set operators, subqueries, and common table expressions to perform advanced data manipulation and retrieval tasks.
Advanced Data Manipulation and Programming
As we move further into the book, we encounter more advanced topics related to data manipulation and programming with Transact-SQL. It covers the use of window functions, ranking functions, and pivot and unpivot operations to perform complex data transformations. The book also discusses the creation and manipulation of views, stored procedures, user-defined functions, and triggers, which are essential for efficient database programming.
