MYSQL: Can you pull results that match like 3 out of 4 expressions?

Question

Say I have a query like this:

SELECT * FROM my_table WHERE name = \"john doe\" AND phone = \"8183321234\" AND email = \"johndoe@yahoo.com\" AND address = \"330 s         


        

Answer 1

Modifying Tomalak's query slightly so that it will use indexes if they are present. Although unless there is an index on each field, a full table scan will happen anyway.

SELECT
*, 
(
    IF(name="john doe", 1, 0) +
    IF(phone = "8183321234", 1, 0) +
    IF(email = "johndoe@yahoo.com", 1, 0) +
    IF(address = "330 some lane", 1, 0) 
) as matchCount
FROM my_table 
WHERE 
    name = "john doe" OR 
    phone = "8183321234" OR 
    email = "johndoe@yahoo.com" OR 
    address = "330 some lane"
HAVING matchCount >= 3
