How to make a selection by coincidence of one value from N fields?

Question

PostgreSQL

something like this (the syntax itself is not correct):

SELECT email,account,mobile_phone AS fields FROM users WHERE fields = "[email protected]"

or

SELECT email,account,mobile_phone FROM users WHERE [email,account,mobile_phone] = "[email protected]"

I'm interested in the option without union or like, if there is such a thing at all ...
* The number of fields can be 10 - 20 pieces. Writing WHERE ... OR seemed not a very good idea

Answer 1

SELECT email,account,mobile_phone FROM users WHERE email = '[email protected]' OR account = '[email protected]' OR mobile_phone = '[email protected]'
