Write powerful SQL queries using SELECT, WHERE, ORDER BY, constraints, functions, and CASE to retrieve and organize data efficiently.
Combine tables with SQL JOINs (INNER, LEFT, RIGHT, FULL) and analyze data using SUM, AVG, COUNT, GROUP BY, HAVING, and subqueries.
Start with SQL basics and progress to more advanced database querying through clear examples and practical exercises.
Requirements
No Programming experience needed
Basic Computer Skills + Internet Access: Familiarity with using a computer, installing software, and navigating the internet.
Description
This course contains the use of artificial intelligence.We are living in the age of Artificial Intelligence, where tools like AI assistants can generate SQL queries in seconds. However, to use these tools effectively, you still need a solid understanding of how databases work and how SQL is structured.This crash course is designed to give you that foundation quickly. Instead of spending months studying theory, you will learn the most important SQL concepts step-by-step so you can confidently understand, verify, and refine SQL queries generated by AI tools better. By the end of this course, you will not only write SQL yourself but also collaborate with AI more effectively when solving real-world data problems.Another important point: once you learn SQL fundamentals, it does not matter much which database system you use. The core SQL concepts are almost the same across popular systems such as PostgreSQL, MySQL, Microsoft SQL Server, Oracle Database, and SQLite.In this course, we use PostgreSQL because it is powerful, widely used, and an excellent choice for learning SQL.Ready to learn SQL step-by-step and fast?Ideal for beginners or anyone looking to strengthen their practical SQL and PostgreSQL skills.By the end of this course, you will:Set up and use PostgreSQL for practical data storage, database management, and efficient queryingUnderstand relational databases, database structure.Start with basic SQL SELECT queries and progress to advanced SQL techniques for real-world tasksCreate and manage database tables using INSERT, UPDATE, and DELETE commands to manipulate dataLearn the theory behind Primary Keys (PK) and Foreign Keys (FK) - and how to use them to maintain relationships between tables in a relational databaseUse essential SQL functions to manipulate strings, dates, and numeric data for better data processingApply logical operators and CASE statements to build dynamic and conditional SQL queriesCombine multiple tables using different types of JOINs - including INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN - for comprehensive data retrievalAggregate and summarize data using functions like SUM, AVG, COUNT, along with GROUP BY and HAVING clauses for advanced data aggregationLearn more about complex problems using subqueries, Common Table Expressions (CTEs), and self joins for sophisticated SQL reportingBuild a strong foundation for success in all data-driven roles, including data analysis, business intelligence (BI), and data engineeringDisclaimer: The subtitle shown on this course was auto-generated by Udemy and may not exactly reflect the instructor's intended message.AI was used to improve the audio quality and double checking the contents.
