Introduction: Learn what SQL is, why it matters, how databases work, and how to set up your full SQL environment.
Querying Data (SELECT): Master SELECT, FROM, WHERE, GROUP BY, HAVING, ORDER BY, DISTINCT, TOP, and query execution order.
Data Definition (DDL): Create, modify, and remove database objects using CREATE, ALTER, and DROP commands.
Data Manipulation (DML): Add, update, and delete records using INSERT, UPDATE, and DELETE with real-world logic.
Filtering Data: Use comparison and logical operators like AND, OR, NOT, BETWEEN, IN, and LIKE to filter data effectively.
Combining Data: Join and merge tables using INNER, LEFT, RIGHT, FULL, CROSS joins and SET operations like UNION, INTERSECT.
Row-Level Functions: Use string, numeric, date, null-handling functions, and CASE expressions to transform your data.
Aggregation & Analytics: Apply aggregate functions and advanced window functions like RANK, DENSE_RANK, LAG, and LEAD.
Advanced SQL Techniques: Work with subqueries, CTEs (recursive and non-recursive), views, temp tables, procedures, and triggers.
Performance Optimization: Improve query speed using indexes, partitions, and practical performance tips.
AI & SQL: Use ChatGPT and GitHub Copilot to generate, explain, optimize, and debug SQL — plus translate and document code.
