Course Description
This course will provide you an understanding of how to use built-in PostgreSQL functions in your SQL queries to manipulate different types of data including strings, character, numeric and date/time. We'll travel back to a time where Blockbuster video stores were on every corner and if you wanted to
watch a movie, you actually had to leave your house to rent a DVD! You'll also get an introduction into the robust full-text search capabilities which provides a powerful tool for indexing and matching keywords in a PostgreSQL document. And finally, you'll learn how to extend these features by using PostgreSQL extensions.The videos contain live transcripts you can reveal by clicking "Show transcript" at the bottom left of the videos.
The course glossary can be found on the right in the resources section.

- Assess when full-text search functions and extensions (to_tsvector, fuzzystrmatch, pg_trgm) provide advantages over pattern matching with LIKE
- Differentiate the results produced by arithmetic and interval operations on DATE versus TIMESTAMP columns
- Evaluate situations that warrant creating or enabling user-defined types, functions, and extensions to extend PostgreSQL capabilities.
- Identify the properties and suitable applications of PostgreSQL data types such as TEXT, NUMERIC, DATE/TIME, and ARRAY
- use built-in string functions—including CONCAT, UPPER/LOWER, SUBSTRING, POSITION, TRIM, LPAD, and RPAD—that reformat, parse, or pad text
