FAQs

Is it worth learning SQL in 2025?

In short, yes—it’s absolutely worth it to learn SQL in 2025. It remains one of the top 10 most in-demand programming languages according to the TIOBE index. Also, there are over 24,000 jobs requiring SQL in the US alone (according to Indeed.com). 

Given its continued relevance and job market demand, investing time in learning SQL could significantly boost your career prospects in the tech industry.

Which SQL course is the best?

Choosing the best SQL course will ultimately depend on your specific needs. For example, if you want to learn basic concepts, a video course like the SQL Tutorial – Full Database Course for Beginners might work well.

However, if your goal is to acquire hands-on experience and land a job, a more interactive course would be a better option. For example, Mimo’s SQL course consists of theory, exercises, and challenges and lets you build a real-life portfolio.

How long will it take to learn SQL?

The timeframe for learning SQL depends on various factors, such as:

• Your current experience and whether you already know another programming language
• Your learning goals (e.g., start a career vs. upgrade your skills)
• How much free time you have
• The learning method you select

On average, you’ll only need a few weeks to pick up the most basic concepts. Acquiring practical intermediate SQL skills might take approximately 6-8 months. Mastering SQL at the advanced level typically requires up to a year of dedicated study and practice.

Can I master SQL in 3 months?

Yes, with 1-2 hours of daily practice, you can achieve job-ready SQL proficiency in 3 months. Many Mimo students land analyst roles within this timeframe using our interactive, gamified approach.

You’ll master basic queries, joins, and database manipulation quickly. However, advanced optimization and complex database design typically require 6-12 months of professional experience.

The key is choosing an interactive course like Mimo that combines theory with hands-on projects, not just passive video watching.

What is the best certification for SQL?

Mimo’s official SQL certification is excellent for beginners, combining practical skills with portfolio building. For enterprise roles, Microsoft SQL Server (MCSA) and Oracle Database certifications carry strong industry weight.

Cloud-focused professionals should consider AWS Database Specialty or Google Professional Data Engineer certifications. Data analysts benefit from IBM Data Science Professional Certificate or Google Data Analytics Certificate.

Start with a comprehensive course like Mimo for foundational skills and certification, then add specialized vendor certifications based on your career path.

Is SQL easier than Python?

SQL is much easier to learn initially. Its English-like syntax (“SELECT name FROM users”) feels intuitive, and most students write basic queries within hours.

Python requires understanding broader programming concepts like variables, loops, and functions, making it harder upfront. However, SQL becomes complex with advanced joins and optimization, while Python’s learning curve is more gradual.

For quick data analysis productivity, SQL is your fastest path to results.

Should I learn Python or SQL first?

Learn SQL first if you want data analysis or business intelligence roles. SQL’s focused scope lets you become job-ready much faster—within weeks rather than months.

With Mimo’s SQL course, you can start extracting insights immediately and qualify for junior analyst positions quickly. Many students land roles using SQL skills, then add Python later for advanced analytics.

Choose Python first only if you want broader programming applications like web development or software engineering.

Is SQL future proof?

Yes, SQL is highly future-proof. Despite being 40+ years old, it continues evolving and remains central to all major cloud platforms (AWS, Google Cloud, Azure).

AI and machine learning still rely heavily on SQL for data preparation. With data volumes growing exponentially and businesses becoming increasingly data-driven, SQL demand continues rising.

The language’s standardization ensures your skills transfer across different database systems, making SQL knowledge a valuable long-term investment.

Can you teach yourself SQL?

While it’s possible to teach yourself SQL, it can be more challenging and time-consuming than structured learning. Self-study requires strong self-discipline and the ability to find and curate quality resources. 

For optimal results, it’s often best to combine self-study with a guided online course like Mimo that offers certification, practical tasks, and a structured curriculum. 

This approach provides a balanced learning experience, ensuring you cover all necessary concepts while gaining hands-on practice and formal recognition of your skills.

Conclusion

We’ve looked at the top 10 courses (both free and paid) that’ll help you master SQL and build a career in this field. Some of the top options include: 

• Mimo SQL course: Best for interactive, simplified learning and practical application for beginners.
• Learn SQL by Codeacademy: Best for practical cheat sheets on SQL.
