Word boundaries in MySQL regular expressions

In regular expressions you can use the zero-width pattern \b to match the beginning or end of a word:

note.title =~ /\bfoo\b/

Unfortunately \b is not available in MySQL. You can use [[:<:]] and [[:>:]] to match the beginning and end of a word instead:

SELECT * FROM notes WHERE title REGEXP "[[:<:]]foo[[:>:]]"

These markers are unique to MySQL and not available in Ruby regular expressions.

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for unsupported versions of Ruby on Rails (2.3, 3.2, 4.2 and 5.2).
