SQL Training

SQL logo transparentOur SQL training courses will teach you how to make the most of this powerful database querying language.

Led by highly experienced database administrators our SQL courses are very hands-on and practical.

We believe that skills are only developed through hands-on practice and so we make sure that you practice the techniques that we teach you. That way you leave the course confident and ready to put them to use.

We offer scheduled SQL training courses at our centres in London and Guildford.

We also provide private training for groups and individuals. This allows us to customise the SQL course topics to your exact requirements, and run it on a date that suits you.

Course Approach


Everything in our course is aimed at making you a faster and more relaxed SQL user. Our SQL courses are deliberately hands-on including lots of practical examples. This ensures that you spend plenty of time constructing and working with SQL queries. We feel strongly that real applicable SQL skills and understanding can only be developed practically. Our exercises are carefully chosen to emphasise the most important aspects of each lesson.

SQL is an incredibly powerful langugage. Although from a high level it can appear deceptively simple, applying its concepts across large complex datasets can soon become complex, requiring a detailed understanding of how it works. The use of multiple exercises ensures that our  delegates are ready to apply their new found understanding of SQL as soon as they return to the office.

It is also important to note that while there are often multiple ways to approach something in SQL. When working with large databases using the correct method to approach an operation can mean that it runs orders of magnitude more quickly, speeding up day-to-day work hugely.

Uses Of SQL


SQL is the international standard language for querying and manipulating relational databases. It allows the user to very quickly interrogate, edit and amend databases and so offers them complete control over a database. As SQL is so widely used a SQL training course is a must have for anyone with aspirations for a career in IT, whether as a database specialist or not.

Microsoft has a very widely used database product SQL Server which is manipulated using SQL as you would expect. Access to SQL Server is also available over the cloud. For more information on courses relating specifically to Microsoft SQL Server click here.

SQL stands for Structured Query Language and is the ANSI (American National Standards Institute) and the ISO (International Organisation for Standardisation) standard language for communicating with relational databases.

Background & Overview


SQL was first developed by IBM during the early 1970’s and is fundamentally unchanged since that time. It’s structure of using Clauses, Expressions, Predicates, Queries and Statements is still used. Clauses being the various parts of a statement or query. Expressions being essentially formulas with produce values or tables. Predicates being conditions that limit a query’s application. Queries selecting a subset of the data in the database according to the various user input criteria and Statements being used to make changes to the databases’s design or set up. Our SQL training courses will lead you through all of these concepts and ensure that you have both the theoretical underpinning and the practical knowledge to make the most of this powerful programming language.

Course Overviews


Introduction SQL Training

This course will give delegates an introduction to the features and capabilities of Structured Query Language (SQL). The course covers elements of ANSI SQL using either Oracle or SQL Server as an example database. After this course, delegates will have a good understanding of the SELECT statement including joining multiple tables, grouping, agregate functions and sorting data.

Advanced SQL Training

This course will further develop your use of SQL to manage a relational database, introducing data manipulation language and database definition language. After this course, delegates will have a good understanding of all DML statements (SELECT, INSERT, UPDATE, DELETE) and all of the DDL statements needed to build database objects (CREATE, DROP, ALTER). This course also covers the use of views, access control, transaction control, advanced select queries and using SQL scripts.
