What you'll learn

  • 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

FAQs

What types of data manipulation does this course cover?

You will learn to manipulate string, numeric, and date/time data using PostgreSQL built-in functions, and work with array data types and full text search capabilities.

Which PostgreSQL functions will I use most in this course?

The course covers date/time functions like EXTRACT and DATE_TRUNC, string functions like SUBSTRING, TRIM, and REVERSE, and full text search functions to_tsvector and to_tsquery, among others.

What dataset is used for the exercises?

All exercises use the Sakila DVD rental database, a normalized schema with films, actors, rentals, and payment records that provides realistic string, numeric, and date/time data to practice on.

What is full text search and why does this course teach it?

Full text search lets you find keywords throughout a document more flexibly than a simple LIKE query. Chapter 4 introduces to_tsvector and to_tsquery, then extends that with the fuzzystrmatch and pg_trgm extensions for similarity matching.

What can I do with PostgreSQL extensions after completing this course?

You will be able to create user-defined data types and functions, and use pg_trgm trigram indexes and fuzzystrmatch to build more powerful and forgiving search queries in your databases.
