sqliteHow do I use regular expressions to query a SQLite database?
Regular expressions can be used in SQLite queries to perform powerful pattern matching. The LIKE operator is used to match a string against a pattern. For example, the following SQLite statement will return all rows where the column name starts with the letter 'A':
SELECT * FROM table WHERE name LIKE 'A%';The % operator is a wildcard that matches any number of characters. Other operators that can be used in regular expressions are _ which matches any single character, [...] which matches any single character that is enclosed in the brackets, and [^...] which matches any single character that is not enclosed in the brackets.
The REGEXP operator can also be used to match a string against a regular expression pattern. For example, the following SQLite statement will return all rows where the column name contains the letter 'A':
SELECT * FROM table WHERE name REGEXP '.*A.*';Code explanation
