Advanced Structured Query Language(SQL) for Database Development and Management Training Course

INTRODUCTION

SQL is the cornerstone of all relational database operations. In this hands-on Writing Advanced SQL Queries course, you will learn how to exploit the full potential of the SELECT statement to write robust queries using the best query method for your application, test your queries, and avoid common errors and pitfalls. It also teaches alternative solutions to given problems, enabling you to choose the most efficient solution in each situation.

SQL (Structured Query Language) is the most popular database language in the world. It is used widely by a variety of database systems to create queries and manipulate data. SQL is generic and compatible with the majority of database systems, which explains its widespread use and why SQL certified individuals are highly valued by businesses.

During this SQL training course, participants will be introduced to the fundamentals of SQL and will gain an insight into the essentials of relational databases. The participants will quickly acquire an understanding of vital querying language concepts and will emerge from this course as well-informed individuals who are able to implement their knowledge immediately within their own organizations.

Throughout this training course, participants will engage in tasks and exercises to ensure that they become familiar with the basic features of SQL in practical terms. On course completion, participants will be able to comfortably use SQL to select, organise, insert, delete, and review data within a database. They will also understand some advanced SQL statements and be familiar with the main functions of SQL such as conversions, SQL syntax, and dates.
