Best SQL course in 2026: 6 SQL trainings compared for professionals and teams

DataCamp is an interactive platform: you write queries in the browser and get instant feedback, with nothing to install. The SQL Fundamentals track takes around 26 hours and covers querying relational databases, joining tables, summary statistics, window functions and built-in PostgreSQL functions. It holds a 4.7 rating from 119 reviews.

Premium costs $28 a month, billed annually. The Teams plan is the same price per user, for 2 people or more, and adds group management, progress tracking and license management. The SQL Associate certification is included with the subscription: you pass one timed exam (SQ101) and one practical exam (SQ501P) within 30 days. It is a vendor certification, not a college credit, but it is a concrete checkpoint for a manager to set.

18 hours of live, project-based training in New York or live online over Zoom, on Eastern time. You work in PostgreSQL with the free DBeaver app. The program covers SELECT queries, filtering and sorting, joins (inner, outer and self), primary and foreign keys, aggregate functions with GROUP BY and HAVING, subqueries, window functions, CASE logic, views, and string and date functions.

Full tuition is $975. Two things stand out for a buyer: a free retake of the class within one year, if a seat is open, and a verified digital certificate of completion. The page shows 4.8 stars from 270 students. It is not a vendor certification, so it proves attendance and practice, not an assessed level.

Learning Tree is an IT training provider whose course pages offer a choice of commercial or government pricing, and Course 925 is its three-day Introduction to SQL. It is a foundation-level, instructor-led course with labs, and the prerequisites line reads simply "None". The outline starts with SQL as the ANSI/ISO standard and moves through single-table SELECT queries, sorting, joins, aggregate functions, transactions with COMMIT and ROLLBACK, and views. Learners finish able to write SQL queries on Microsoft SQL Server or PostgreSQL.

The page shows two live-instructor prices, $2,785 and $2,049, under a commercial-or-government pricing choice, without labeling which is which in the text; we use the higher one, and a company buyer should ask which applies. It includes after-course one-on-one coaching, an after-course computing sandbox and a Learning Tree end-of-course exam. In-class attendance earns 17 NASBA CPE credits, useful for finance and accounting staff. Sessions run in a classroom or virtually, some are flagged guaranteed to run, and the page offers to run the course for a team.

A four-module course from UC Davis, taught by Sadie St. Lawrence. Coursera suggests 2 weeks at 10 hours a week; the module durations add up to about 15 hours. It is one of the most taken SQL courses online, with more than 730,000 learners enrolled and a 4.6 rating from more than 17,000 reviews.

You can enroll for free. The shareable certificate, which you can add to your LinkedIn profile, needs a paid upgrade: you buy the Certificate experience when you enroll, or you take the course through Coursera Plus, the subscription that includes it. The course aims at data science work: filtering, sorting, joins and the logic of asking questions of data. It is a good start, but it stops before the advanced analysis patterns a working analyst uses daily.

ONLC is a US training company with centers across the country, and DP-080: Transact-SQL Querying is its two-day course on Microsoft's dialect of SQL. It targets anyone who needs to write basic SQL or T-SQL queries: data analysts, data engineers, database administrators, and people who sit next to the data, like solution architects or technology managers. The queries run on SQL Server-based systems: Microsoft SQL Server, Azure SQL Database and Azure Synapse Analytics.

The outline has five modules, each with a lab: getting started with T-SQL and SELECT, sorting and filtering (ORDER BY, paging, WHERE, DISTINCT), joins and subqueries, built-in functions with grouping and aggregates, and modifying data with INSERT, UPDATE, DELETE and MERGE. The fee is $1,195. You attend at an ONLC location or join the same live class from home or the office through its Remote Classroom Instruction. For a company, ONLC can deliver the class for your group, has a self-service price quote form, and offers Learning Credits as a savings option. In Virginia it only accepts students sponsored by their employer, which tells you who it really sells to.

LearnSQL.com only does SQL, and it shows. The All Forever plan gives lifetime access to all 82 present and future courses for a one-time payment of $149. A single course costs $39, and a free plan opens the free section of every course without a credit card. The courses are hands-on: you type queries in the browser and move on when they run.

For companies, there is a business offer with custom courses, assignments and progress tracking, on request. The provider also links to a Certificate of Competency in SQL. What you will not get is a live instructor or a widely known certification.
