Compare Columns Where One is Similar to Part of Another

Question

I\'m trying to write a Select statement where I can see if one column is like part of another.

tblNames 
ID    FullName                   FirstName
1     Mr.         


        

Answer 1

This worked for me:

SELECT *
FROM `table`
WHERE `col1` NOT LIKE CONCAT('%', `col2`, '%')

Found it here: http://www.edmondscommerce.co.uk/mysql/compare-two-columns-in-mysql/

Somehow it only worked correctly with the concat-function (?).
