Using something similar to a CASE WHEN in Phalcon query builder

Question

$fileQueryBuilder->columns(
            [
                "id" => "d.discovered_file_id",
                "company_name" => "d.company_name"
            ]
        );

This is the part of my query builder where I mention the column names to be selected/displayed. Can I handle the 'company_name' field to show it's value if it has one, and something like 'Not available' if it's empty, in this part of the query builder itself? Is there a way of doing that, like using a CASE WHEN same as in SQL?

What I tried-
CASE WHEN d.company_name IS NOT NULL THEN d.company_name ELSE 'Not available' END => d.company_name , but this doesn't work.

Answer 1

Isn't IF better in this case?

IF(d.company_name IS NOT NULL, d.company_name, 'Not available') as company_name

Also PHQL only supports case syntac like this:

CASE column WHEN value THEN some expression ELSE some expression END
