Description of the Language SQL Training Course
Whether you are an analyst, developer, manager or beginner in the world of data, SQL is the key to effectively querying and exploiting a database. Understanding how to structure a query, filter results, aggregate values or link multiple tables is now essential in many professions.
This training course provides you with a solid foundation to become self-sufficient in querying and analysing relational data, with a progressive and 100% practical approach.
Also discover our MariaDB + Galera Cluster Training Course, our Oracle Data Guard Training Course, our MySQL Training Course, our PostgreSQL Training Course and our SQL Server 2025 Training Course.
Format
Remote (recorded sessions).
GOOD TO KNOW
This training course includes numerous exercises (60% practical) to enhance learning. Even if you are the only one registered, the session will still take place (except in cases of force majeure). A preliminary interview is held between the participant and/or a company representative in order to fully assess the participant’s profile (level, needs, professional context, challenges, etc.).
Assessment : during the training course, the trainer assesses the participants’ progress through multiple-choice questions, role-playing exercises and practical work. Participants receive a certificate of completion at the end of the training course.
This training course is part of our Database Training Courses. Discover our other database and BI courses to model, exploit and add value to your business data.
objectives of this Language SQL Training Course
By the end, each participant will be able to :
- Understand the structures of a relational database (tables, columns, relationships)
- Learn how to formulate simple and complex SQL queries
- Use filters, sorts, aggregates and joins
- Manage subqueries and built-in functions
- Create views, aliases and understand basic performance
- Gain autonomy in interpreting raw data
Prerequisites
- Knowledge of how to use a workstation (Windows, Mac or Linux)
- No prior knowledge of SQL or databases required
- A background in data, management, support, analysis or IT is recommended
- Because each participant has a unique background and expectations, a preliminary interview with our expert allows us to precisely identify their objectives, level and professional challenges.
This enables us to tailor the training content to ensure relevant and personalised learning.
Target Audience
Perfect for technical and non-technical profiles wishing to manipulate databases (PostgreSQL, MySQL, Oracle, SQL Server, etc.).

FAQ – SQL Language Training
What is SQL used for?
SQL (Structured Query Language) is the standard language for managing and querying relational databases — Oracle, SQL Server, PostgreSQL, MySQL, MariaDB, SQLite, and most cloud database services. It covers data retrieval (SELECT), modification (INSERT, UPDATE, DELETE), schema definition (CREATE, ALTER), and access control (GRANT, REVOKE). It remains a foundational skill for developers, analysts, and data engineers. MFE-IT trains professionals on SQL through hands-on labs on real datasets.
Is SQL hard to learn?
SQL is one of the easier languages to start with — basic SELECT queries are accessible within hours. Mastery (joins, subqueries, window functions, query optimization, transaction isolation) takes longer and depends on practice with realistic data volumes. The MFE-IT SQL Language training compresses the learning curve from beginner to confident practitioner with structured progression.
What is the difference between SQL and MySQL?
SQL is the language. MySQL is one specific relational database management system that implements SQL (with MySQL-specific extensions). Other databases — PostgreSQL, Oracle, SQL Server, MariaDB, SQLite — all implement SQL with their own dialects and extensions. Through MFE-IT’s hands-on approach, learners write portable SQL while understanding vendor-specific differences.
What is a JOIN in SQL?
A JOIN combines rows from two or more tables based on a related column. INNER JOIN returns matching rows from both, LEFT/RIGHT JOIN returns all rows from one side plus matches, FULL OUTER JOIN returns everything, and CROSS JOIN produces a cartesian product. JOINs are central to relational queries. Our MFE-IT training course on SQL covers each JOIN type with diagrams and progressively complex examples.
