SQL Primer: An Accelerated Introduction to SQL Basics

Title: SQL Primer: An Accelerated Introduction to SQL Basics | Author(s): Rahul Batra | Publisher: Apress | Year: 2018  | Language: English | Pages : 212 | Size: 2 MB | Extension: pdf

 

Build a core level of competency in SQL so you can recognize the parts of queries and write simple SQL statements. SQL knowledge is essential for anyone involved in programming, data science, and data management. This book covers features of SQL that are standardized and common across most database vendors. You will gain a base of knowledge that will prepare you to go deeper into the specifics of any database product you might encounter.

Examples in the book are worked in PostgreSQL and SQLite, but the bulk of the examples are platform agnostic and will work on any database platform supporting SQL. Early in the book you learn about table design, the importance of keys as row identifiers, and essential query operations. You then move into more advanced topics such as grouping and summarizing, creating calculated fields, joining data from multiple tables when it makes business sense to do so, and more. Throughout the book, you are exposed to a set-based approach to the language and are provided a good grounding in subtle but important topics such as the effects of null value on query results.

With the explosion of data science, SQL has regained its prominence as a top skill to have for technologists and decision makers worldwide. SQL Primer will guide you from the very basics of SQL through to the mainstream features you need to have a solid, working knowledge of this important, data-oriented language.

What Youll Learn:
• Create and populate your own database tables
• Read SQL queries and understand what they are doing
• Execute queries that get correct results
• Bring together related rows from multiple tables
• Group and sort data in support of reporting applications
• Get a grip on nulls, normalization, and other key concepts
• Employ subqueries, unions, and other advanced features

Anyone new to SQL who is looking for step-by-step guidance toward understanding and writing SQL queries. The book is aimed at those who encounter SQL statements often in their work, and provides a sound baseline useful across all SQL database systems. Programmers, database managers, data scientists, and business analysts all can benefit from the baseline of SQL knowledge provided in this book.
