This course covers a wide range of SQL techniques, beyond basic CRUD (Create, Read, Update, and Delete) operations in PostgreSQL. You will learn the specifics of aggregation, transactions, reading and parsing CSV files and inserting data into a database. You’ll also take a look at how PostgreSQL handles and indexes text data.
Specifically, students will do assignments that alter table schemas, create stored procedures, construct advanced queries, explore sorting and grouping query data, and techniques for working with text in databases including regular expressions.
In this first week, you'll be introduced to the course and look at SQL commands for editing columns and tables in a PostgreSQL Database. You'll learn to create stored procedures and also utilize the SELECT DISTINCT command.
Using SQL Techniques
This week, we'll focus on producing properly normalized tables from CSV files and utilizing the ALTER TABLE command to adjust the schema of tables.
Text in PostgreSQL
This week will focus on text in PostgreSQL, including utilizing character sets, identifying hashtag algorithms and attributes, as well as index choices and techniques.
In our final week, we will focus on regular expressions: their functions, and how to construct them to select rows from a table that match a pattern.
