FAQ
SQL: frequently asked questions
Which tools are used in SQL training?+
Hands-on work runs on postgreSQL and mySQL. Those tools come from the SQL program itself, delivered on site over 1 day, so participants practise on the stack they will use at work.
What can participants do after SQL training?+
They can master complex joins and subqueries in SQL for in-depth professional analyses, optimize SQL query performance in a certifying enterprise context and develop advanced skills in indexing and views for efficient databases. Those are the stated objectives of the SQL program at Intermediate level, checked by the end-of-session assessment.
How is SQL training assessed?+
Assessment relies on interactive quizzes at the end of modules on advanced SQL queries, practical exercises evaluated in real-time on PostgreSQL/MySQL databases and business case study with presentation and personalized feedback. Learni issues a completion certificate together with the individual assessment report at the end of the SQL program, which an L&D team can file as evidence.

1 day, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.

SQL basics (SELECT, WHERE, GROUP BY, ORDER BY), relational database concepts, basic PostgreSQL or MySQL usage.
Is a certificate issued after SQL training?+
