Udacity’s SQL Nanodegree (nd072) is a 41-hour beginner program in two parts: a long querying course that runs from SELECT statements to window functions and query tuning, and a database course that covers normalization, schema design, indexes and non-relational stores. It has two reviewed projects and was rated 4.6 from 310 reviews when we checked it on 13 October 2026.

What it costs

Udacity sells access by subscription. On 13 October 2026 the program page offered $249 a month, $846 for a four-month bundle (about $212 a month), or $999 to buy just this program outright. A subscription covers Udacity’s wider catalog as well, so if you plan to take a second program, such as the Data Analyst Nanodegree, the bundle is easier to justify. The page also showed a 40% discount banner for new users; check the terms at checkout because promotions change often.

Because the whole program is 41 hours, the monthly plan is usually the cheapest route. Someone who studies 10 hours a week finishes the lessons in about a month, and project reviews add a few days each. The one-time $999 price only makes sense if you study slowly and want no time pressure at all.

What You’ll Learn

The program is split into a short welcome section and two real courses. The first is long and practical; the second is shorter and more conceptual, and it is where the program goes beyond most SQL tutorials.

Course 1: Introduction to SQL (about 18 hours)

Despite the title, this course goes well past the introduction. Lessons are short and narrowly focused, which makes it easy to slot into a commute or lunch break. In order, it covers:

• Query basics: entity relationship diagrams, SELECT and FROM, LIMIT, ORDER BY, WHERE, arithmetic operators, LIKE, IN, AND, BETWEEN, NOT and OR.
• JOINs: inner joins, then left, right and full outer joins, joins with comparison operators, self joins and UNION.
• Aggregation: NULLs, COUNT, SUM, MIN, MAX and AVG, GROUP BY, DISTINCT, HAVING, date functions and CASE statements.
• Subqueries and temporary tables: subqueries in WHERE and FROM clauses, common table expressions (CTEs) and temporary tables, plus a lesson on writing clean, efficient SQL.
• Window functions: PARTITION BY, ordering inside a window and building your own window function.
• Data cleaning: two lessons on cleaning messy data with SQL.
• Performance tuning: how query plans work and how to make slow queries faster.

The window functions and data cleaning lessons are the most valuable part for analysts. Many free tutorials stop at GROUP BY, but ranking, running totals and cleaning data are what analyst take-home tests and interview questions ask for.

Course 2: Management of Relational and Non-relational Databases (about 22.5 hours)

This is the part most SQL courses skip. You move from querying someone else’s tables to designing your own. Lessons cover the difference between relational and non-relational databases, normalizing data, data definition language (CREATE, ALTER), data manipulation language (INSERT, UPDATE, DELETE), constraints that enforce business rules, indexes for performance, and an introduction to non-relational databases. Udacity’s course description says you choose between Postgres, MongoDB and Redis for different scenarios.

The old version of this review said the program had no database design or NoSQL coverage. That is no longer true, and this course is the main reason to pick the Nanodegree over a cheaper query-only course.

The two projects

• Deforestation Exploration: you apply the course’s querying skills to forest and land data to help decide where efforts to combat deforestation should concentrate. Write your findings up as a short recommendation when you publish it: a hiring manager learns more from a query that leads to a decision than from the query alone.
• Udiddit, A Social News Aggregator: you inherit a badly designed database for a Reddit-style site, design a normalized and performant replacement, and migrate the existing data into it. This is closer to what a data engineer or backend developer does, and it is the harder of the two.

Each project is graded by a Udacity reviewer against a published rubric, and you can resubmit until it passes. Udacity’s project review timeline says reviews are often done in 48 to 72 hours but can take up to a week at busy times.

Who teaches it

Udacity lists four instructors: Ziad Saab (software developer and co-founder of DecodeMTL), David Elliott (data scientist and data engineer), Derek Steer (CEO of Superframe) and Malavica Sridhar (senior product manager at CircleUp).

Who Should Enroll?

• Career changers aiming at data analyst or business intelligence roles who already know basic SELECT queries and want to reach interview level.
• Excel-heavy analysts who want to pull and clean their own data instead of waiting on an engineer.
• Product managers and marketers who need to answer their own questions from a company database.
• Junior developers who can write queries but have never designed a schema, normalized tables or added an index.

If you already write window functions and CTEs at work, the first course will feel slow. Skip straight to a database design or data engineering program instead, such as the Data Engineering with AWS Nanodegree.

The prerequisite, in plain terms

Udacity lists “Basic SQL” as the only prerequisite and links a short Udacity SQL course for it. In practice that means you should be able to read a simple SELECT … FROM … WHERE query and guess what it returns. You do not need Python, statistics or any programming background.

A quick readiness check

Try these three questions on any practice database. If you can answer them in a few minutes, you are ready for the Nanodegree. If not, spend a weekend on a free course first.

1. Return the ten most recent orders, newest first.
2. Count orders per customer and show only customers with more than five orders.
3. List every customer, including those with no orders at all.

The third question needs a LEFT JOIN. If that is new to you, the first course covers it, but the pace will be faster than a true beginner course.

Pros and Cons

Pros:

• Short: 41 hours fits inside one or two months of subscription, which keeps the real cost far below the program’s list price.
• Covers database design, normalization, indexes and an introduction to MongoDB and Redis, which most SQL courses leave out.
• Window functions, CTEs and data cleaning each get full lessons with exercises.
• Two human-reviewed projects that work as portfolio pieces for analyst and junior data engineering roles.
• Rated 4.6 from 310 reviews on Udacity’s page, among the stronger ratings in Udacity’s data catalog.

Cons:

• Expensive for what is partly free elsewhere: much of the querying course overlaps with Udacity’s free SQL for Data Analysis course.
• No stored procedures, transactions in depth or database administration, so it is not a DBA course.
• The certificate is a Udacity certificate, not a vendor certification like Microsoft’s or Oracle’s.
• Project reviews can take up to a week at busy times, and some learners on Trustpilot report slow support tickets.

What learners say

The five newest reviews on Udacity’s own nd072 page (June to August 2026) are all five stars and short, mostly praising clear explanations. That is a small, self-selected sample, so we also read the 60 most recent reviews of Udacity as a whole on Trustpilot, where Udacity scored 4.5 from 3,406 reviews on 13 October 2026. Most were positive about structured lessons and project feedback. The negative ones repeated three themes: project reviews pending for weeks, in-browser workspaces or terminals that stopped working, and support tickets left unanswered. One reviewer also said newer courses contain mistakes that look AI-generated. None of the complaints named the SQL program, but they describe platform risks you should plan for.

The same question comes up on Reddit: in an r/SQL thread, a career changer leaving a finance role asked whether Udacity’s beginner SQL course was worth paying for. Our answer is that the syntax is free to learn; what you pay for here is structure, reviewer feedback and two projects you can show.

Is the SQL Nanodegree Worth It?

Yes, for one specific buyer: someone who already knows basic queries, wants to reach a level where they can pass an analyst take-home test, and values human feedback on two portfolio projects. Finished in one month at the list price of $249, it is good value compared with most bootcamp-style SQL programs. The database design course is the part that justifies the price, because free resources rarely teach normalization and indexing with a reviewed project at the end.

No, if you only need to write queries. In that case, start with Udacity’s free SQL for Data Analysis course, DataCamp’s SQL track or SQLBolt, and spend the money elsewhere.

How it compares with the alternatives

SQLBolt is free and pays us nothing; we list it because it is a good first step. Udacity’s free course is the closest substitute for the first half of the Nanodegree, and it is rated 4.7 from 608 reviews.

What SQL skills lead to

SQL remains one of the most widely used technical skills. In the 2025 Stack Overflow Developer Survey, 58.6% of all respondents said they use SQL, PostgreSQL was the most used database at 55.6%, and MySQL followed at 40.5%. The US Bureau of Labor Statistics does not track a separate data analyst occupation, but SQL is a core skill in roles it does track, such as data scientists, whose median pay was $120,230 in May 2025. SQL alone rarely gets you hired; pair this program with a visualization tool and a portfolio of analyses.

A four-week plan to finish inside one month

The cheapest way to take this program is to finish it inside a single monthly billing period. This plan assumes about 10 hours a week and the Basic SQL prerequisite. It front-loads the first project so the review wait overlaps with the database course.

If a project comes back with required changes, fix them the same day. A second review adds another wait, and that is how a one-month plan turns into two.

Ways to lower the cost

• Ask your employer first. Udacity sells business plans, and several recent Trustpilot reviewers said they took Udacity courses through employer training, Accenture among them. If your company already pays, the program costs you nothing.
• Learn the basics for free. Do Udacity’s free SQL for Data Analysis course before you subscribe. You will move through the paid querying course much faster.
• Time the subscription. Subscribe when you have a clear month, not a busy one. A paused month is the most expensive month.
• Use the new-user discount if it is running. Udacity showed a 40% banner for new users on 13 October 2026. Our links pass you to Udacity’s own checkout, where the current offer is shown.

What to take next

If you finish the SQL Nanodegree and want to continue on Udacity, the natural next steps are the Data Analyst Nanodegree for Python and statistics, or the Programming for Data Science with Python Nanodegree if you are new to Python. For a wider view of options, see our best SQL courses guide.

Frequently Asked Questions

Is the Udacity SQL Nanodegree worth it?

It is worth it if you want graded, reviewed projects and a structured path from basic queries to database design, and you can finish in one or two months of subscription. At $249 a month, it is poor value if you only need query basics: Udacity’s own SQL for Data Analysis course is free and covers much of the first course, and DataCamp or SQLBolt teach the same syntax for less.

What is a Udacity Nanodegree?

A Nanodegree is Udacity’s name for a multi-course program built around projects that a human reviewer grades against a rubric. You get a Udacity certificate when every project passes. It is not a college degree or academic credit, and it is sold through Udacity’s subscription rather than as a separate tuition.

How long does the SQL Nanodegree take?

Udacity estimates 41 hours. At 10 hours a week that is about four to five weeks, plus a few days per project for review. Most learners with the prerequisite can finish inside one or two months of subscription.

Do I need to know SQL before starting?

Udacity lists one prerequisite, Basic SQL. The first course still starts with SELECT, WHERE and ORDER BY, so a complete beginner can follow it, but the pace assumes you have seen a query before. If you have never written one, spend a weekend on Udacity’s free SQL for Data Analysis course or SQLBolt first.

Does the Udacity SQL Nanodegree teach MySQL?

No. The program teaches standard SQL, and its database course works with Postgres, plus MongoDB and Redis on the non-relational side. Almost everything carries over to MySQL: SELECT, JOINs, GROUP BY, subqueries and window functions work the same way, with small differences in date functions and some syntax.

Is the Udacity SQL certificate recognized by employers?

It is a Udacity certificate, not an industry certification like those from Microsoft or Oracle, and not academic credit. Employers care more about what you can show: the Deforestation Exploration analysis and the Udiddit database redesign are better evidence in an interview than the certificate itself.

How much does the SQL Nanodegree cost?

Udacity charged $249 a month, $846 for four months (about $212 a month) or $999 to buy the program outright on 13 October 2026, and showed a 40% discount banner for new users. Because the program is only 41 hours, the monthly plan is usually the cheapest route.

Can I get a refund?

Udacity’s Terms of Use (updated January 16, 2026) give seven days from your first purchase to cancel for a full refund. After that, fees are not refunded, and canceling a monthly plan keeps access until the end of the month you paid for.

Is SQL still worth learning in 2026?

Yes. In the 2025 Stack Overflow Developer Survey, 58.6% of all respondents said they use SQL, and PostgreSQL was the most used database at 55.6%. SQL appears in most data analyst, data engineer and business intelligence roles.
