Search for "whole word match" in MySQL

 

 

You can use REGEXP and the [[:<:]] and [[:>:]] word-boundary markers:

SELECT *
FROM table 
WHERE keywords REGEXP '[[:<:]]rid[[:>:]]'

Update for 2020: (actually 2018+)

MySQL updated its RegExp-Engine in version 8.0.4, so you will now need to use the "standard" word boundary marker \b:

SELECT *
FROM table 
WHERE keywords REGEXP '\\brid\\b'

Also be aware that you need to escape the backslash by putting a second backslash.
