Introduction to SQL: Querying the Movie Database
Learn the fundamentals of SQL by querying a realistic Movie database. This beginner-friendly course covers core data retrieval concepts including SELECT, FROM, WHERE, and ORDER BY clauses.
Introduction to Relational Databases Define what a relational database is and why it is useful. Identify the basic structure of a database table, including rows and columns. Recognize the specific schema of the Movie table used in this course. Retrieving Data: SELECT and FROM Understand the purpose of the SELECT and FROM clauses in an SQL query. Write a query to retrieve specific columns from the Movie table. Use the asterisk (*) wildcard to retrieve all columns from a table. Filtering Data: The WHERE Clause Explain how the WHERE clause filters data based on specific conditions. Write queries using basic comparison operators (e.g., =, >, <) with numeric data. Write queries to filter text data, such as finding movies of a specific genre. Sorting Results: ORDER BY Organize query results alphabetically or numerically using the ORDER BY clause. Differentiate between ascending (ASC) and descending (DESC) sorting. Combine SELECT, FROM, WHERE, and ORDER BY clauses into a single, comprehensive query.
