SQL
Whether you’re managing large datasets or writing your first query, build your SQL skills with this practical guide! Learn the basic elements of relational databases and walk through the syntax, features, and applications of SQL. Then dive into the sublanguages of SQL and apply them for tasks such as modifying tables and querying data. See SQL in action with an example PostgreSQL database and detailed code samples from real-world applications!
- Master SQL programming for database management and manipulation
- Learn to use the five SQL sublanguages: DDL, DML, TCL, DQL, and DCL
- Define schemas and tables; modify and query data; and configure database authorizations
You'll learn about:
- Relational Database Elements:
Understand the fundamentals of relational databases and schemas. Learn the elements of database structures, from tables to views to keys. Then review more advanced concepts like normalization, stored procedures, triggers, and authorization.
- Setting Up Your Environment:
Follow click-by-click instructions to install and set up a local PostgreSQL database and a pgAdmin or Visual Studio Code IDE. See a SQL demo in action in your environment and experiment with code samples.
- SQL Sublanguages:
Use the sublanguages of SQL for your daily tasks. Start by creating and altering database objects. Insert, update, and delete data in tables and then modify multiple tables together. Query data from single or combined tables and limit data access using authorizations.
