Hands-On: Learn PostgreSQL
Learn PostgreSQL from scratch through hands-on coding exercises in a PostgreSQL web editor, progressing from basic SELECT queries to advanced features like window functions, CTEs, indexing, query analysis, and transactions with AI-assisted learning.
What you'll learn
- Understand and practice core SQL querying in PostgreSQL (SELECT, WHERE, JOINs, GROUP BY, HAVING)
- Work with advanced PostgreSQL features like window functions, CTEs, indexes, and query analysis
- Design and manage schemas, tables, constraints, and data types effectively
- Perform robust data operations including INSERT, UPDATE, DELETE, transactions, and views
- Use PostgreSQL built-in functions for text, numeric, date/time, and conditional logic
Skills you'll gain
- Write efficient SQL queries using SELECT, WHERE, ORDER BY, LIMIT, and aggregates
- Filter, group, and aggregate data with GROUP BY, HAVING, and set operations
- Join data across multiple tables using inner, outer, cross, and self joins
- Insert, update, and delete data safely, including using RETURNING and UPSERT
- Use text, numeric, date/time, and conditional functions in PostgreSQL
- Work with subqueries and common table expressions (including recursive CTEs)
- Design tables with appropriate data types and constraints (PK, FK, UNIQUE, CHECK, DEFAULT)
- Manage schema changes with ALTER TABLE and related DDL operations
- Create and manage indexes to improve query performance
- Analyze and optimize queries using EXPLAIN and EXPLAIN ANALYZE
- Use window functions for ranking, running totals, and advanced analytics
- Create and manage views and materialized views
- Handle transactions with BEGIN, COMMIT, ROLLBACK, SAVEPOINT, and isolation levels
