This section guides you through the essential setup process. You'll learn how to download and install PostgreSQL (3:02), create a new database (1:09), and restore the Airlines database (1:13) – your hands-on environment for the remainder of the course. Two lectures then give a detailed overview of the database itself (2:11, 3:54), culminating in an explanation of SQL Data Types (1:13).
Beginner: Core SQL – SELECT Statements
Building your foundation, this section introduces the core `SELECT` statement (4:54). You'll tackle a challenge to solidify your understanding (2:55) and apply it to various Airlines Database tables (3:34), then learn how to use the `DISTINCT` keyword (1:53).
Beginner: Core SQL – WHERE Clause & Operators
Master data filtering with the `WHERE` clause (7:15) and various operators (4:43). You’ll practice combining `AND` and `OR` (3:14), using `LIKE` (4:57), and working with `BETWEEN`, `IN`, and the `AS` keyword (5:51).
Beginner: Core SQL – Data Ordering & Filtering
This section covers refining your results using `LIMIT` and `ORDER BY` (7:49), distinguishing between `FETCH` and `LIMIT` (2:54). You'll also explore `NOT IN`, `ISNULL`, `IS NOT NULL`, and data type casting using `CAST` (3:55, 2:56, 3:55).
Intermediate: SQL Aggregations & Grouping
This section introduces aggregate functions, starting with `COUNT()` (4:09). Learn to use `SUM()`, `MIN()`, `MAX()`, and `AVG()` (0:59, 1:55), mastering the power of `GROUP BY` and `HAVING` clauses (2:08) to group and filter aggregated data.
