Yes, I have 2 Overwatches. One is on Steam and one from Battle[dot]net. This is my personal computer, I've been writting softwares for a long time, but I don't really talk about them on my profile, DataGrip is my comfortable tool, I know pgAdmin exist but, DataGrip just better. I also have InteliJ IDEA, Rider,... like a lot of essential developer tools on my computer.

Iโ€™ve been building a no-code PostgreSQL editor. Not a startup, just an open-source project. If youโ€™ve ever used pgAdmin, youโ€™ll probably wish you had this much earlier. pglens.org

SQL ROADMAP 2026 ๐Ÿ—„๏ธ If I were starting SQL in 2026, I wouldn't waste months jumping between random tutorials. I'd focus on mastering the skills companies actually pay for. Because SQL isn't just a database language. It's one of the highest ROI skills in tech. Whether you're aiming for: โ€ข Data Analyst ๐Ÿ“Š โ€ข Data Scientist ๐Ÿค– โ€ข Backend Developer ๐Ÿ’ป โ€ข Business Analyst ๐Ÿ“ˆ โ€ข Data Engineer โšก โ€ข Product Manager ๐Ÿš€ SQL is often the common requirement. Here's the roadmap I'd follow: โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 1: SQL FUNDAMENTALS Learn: โœ“ SELECT โœ“ WHERE โœ“ ORDER BY โœ“ LIMIT โœ“ DISTINCT โœ“ Aliases Goal: Retrieve exactly the data you need. Example: SELECT name, salary FROM employees WHERE salary > 50000; โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 2: FILTERING & CONDITIONS Master: โœ“ AND / OR โœ“ IN โœ“ BETWEEN โœ“ LIKE โœ“ IS NULL โœ“ CASE Statements Most interview questions start here. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 3: AGGREGATIONS Learn: โœ“ COUNT() โœ“ SUM() โœ“ AVG() โœ“ MAX() โœ“ MIN() โœ“ GROUP BY โœ“ HAVING Example: SELECT department, COUNT(*) FROM employees GROUP BY department; This is where real business reporting begins. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 4: JOINS The most important SQL topic. Master: โœ“ INNER JOIN โœ“ LEFT JOIN โœ“ RIGHT JOIN โœ“ FULL JOIN โœ“ SELF JOIN If you understand joins well, you're ahead of most beginners. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 5: SUBQUERIES Learn: โœ“ Nested Queries โœ“ Correlated Subqueries โœ“ EXISTS โœ“ NOT EXISTS This teaches you how databases think. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 6: WINDOW FUNCTIONS This is where average developers stop. Learn: โœ“ ROW_NUMBER() โœ“ RANK() โœ“ DENSE_RANK() โœ“ LEAD() โœ“ LAG() โœ“ NTILE() These appear constantly in real-world analytics jobs. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 7: COMMON TABLE EXPRESSIONS Master: โœ“ WITH Clause โœ“ Recursive CTEs Cleaner code. Easier debugging. Better interviews. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 8: DATABASE DESIGN Understand: โœ“ Primary Keys โœ“ Foreign Keys โœ“ Normalization โœ“ Relationships โœ“ Indexing This separates SQL users from database professionals. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 9: ADVANCED SQL Learn: โœ“ Views โœ“ Stored Procedures โœ“ Triggers โœ“ Transactions โœ“ ACID Properties These topics show up frequently in backend and DBA interviews. โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”น STAGE 10: SQL INTERVIEW PREPARATION Practice: โœ“ Top N Problems โœ“ Duplicate Records โœ“ Second Highest Salary โœ“ Running Totals โœ“ Cohort Analysis โœ“ Customer Retention Queries Solve at least: โ€ข 100 SQL Questions โ€ข 50 Join Problems โ€ข 50 Window Function Problems โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” ๐Ÿ”ฅ BONUS: TOOLS TO LEARN โœ“ PostgreSQL โœ“ MySQL โœ“ SQL Server โœ“ DBeaver โœ“ pgAdmin โœ“ DataGrip โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ”โ” Most people think SQL is easy. Writing a SELECT query is easy. Writing efficient queries on millions of rows is where the skill begins. SQL has been around for decades. And it's still one of the most valuable skills in tech. Save this roadmap. You'll thank yourself in 12 months. โ™ป๏ธ Repost to help someone learn SQL in 2026. #SQL #DataAnalytics #DataScience #Database #PostgreSQL #MySQL #BackendDevelopment #DataEngineering #Programming #TechCareer

pgAdmin feels like 2008. Cloud GUIs want your credentials on their servers. pglens 3.0: modern React UI, fully local, no-code first, SQL when you want it, MIT licensed. Browse, visualize, query, back up โ€” all from one tab.

Supabase is nothing more that PostgreSQL hosted in a server that is located in a computing cloud. All it does, it exposes HTTP API in addition to the direct postgres connection. The GUI is confusing as hell. I'd rather host PostgreSQL in my own computer and use PGAdmin.

pgAdmin is slow. Query is fast. Use query. querydb.dev
