We will utilize the percent wildcard with the LIKE operator to find a substring “function” from the article_title column: SELECT article_title We have created a table named “article_info”, whose data is shown in the following snippet: SELECT * FROM article_info Use the wildcards to specify a pattern of your choice in place of a pattern.Įxample 1: How Does the LIKE Operator Work? Use the below-specified syntax to perform text matching using the LIKE operator: SELECT FROM tab_name The LIKE operator is case sensitive, which means the LIKE operator will consider “ABC” and “abc” two different strings and hence retrieves false in such a case. The LIKE operator matches the search expression with the specified pattern and retrieves true if the match is found. What is a LIKE Operator and How Does it Work? This write-up will teach you the difference between LIKE, ILIKE, and NOT LIKE operators in PostgreSQL. The percentage wildcard "%" matches sequences of characters, while the underscore "_" matches a single character. Two types of wildcards are used in Postgres to specify a pattern: a percentage sign, “%,” and an underscore sign, “_”. In PostgreSQL, LIKE, NOT LIKE, and ILIKE operators are used along with the wildcards to perform the pattern matching.
