Using mysql concat() in WHERE clause?

Question

I would like to search my table having a column of first names and a column of last names. I currently accept a search term from a field and compare it against both columns

Answer 1

To Luc:

I agree with your answer, although I would like to add that UPPER only works on non-binary elements. If you are working with say an AGE column (or anything numeric) you will need to perform a CAST conversion to make the UPPER function work correctly.

SELECT * FROM table WHERE UPPER(CONCAT_WS(' ', first_name, last_name, CAST(age AS CHAR)) LIKE UPPER('%$search_term%');

Forgive me for not responding to Luc's answer directly but for the life of me I could not figure out how to do that. If an admin can move my post, please do so.
