Introduction to SQL

Introduction to SQL Course Overview

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. Therefore, SQL certified individuals are very much valued for their extensive knowledge and skill. SQL is generic, thus is compatible with the majority of database systems, which explains its widespread use, prominence, and the need for training in this crucial area.

During this course, delegates will be introduced to the fundamentals of SQL and will gain an insight into the essentials of relational databases. As this is a one day course, delegates will swiftly 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 organisation.

Throughout this training course, delegates will engage in tasks and exercises to ensure that they become familiar with the basic features of SQL in practical terms. On course completion, delegates will be able to comfortably use SQL. Attendees will not be experts (if this is desired, see our ), but will be able to use SQL to conduct daily tasks and queries. Most importantly, delegates will be able to use SQL to select, organise, insert, delete, and review data within a database. They will also possess an understanding of some advanced SQL statements and will be familiar with the main functions of SQL such as conversions, SQL syntax, and dates.
