MySQL: return “0” & “1” rather than “false” & “true”

Question

I need to return true or false rather than 1 & 0, using following query:

select if(u.id is null,false

MySQL has no boolean datatype, so you need to stick with 0 and 1 on the MySQL side:

select if(u.id is null, 0, 1) status_int
from user u
limit 10

If you prefer a boolean over 0/1 in PHP, you can cast it like this:

$status = (bool) $status_int;
