It seems equally as bad as select *. There's a number of reasons why select * are bad - http://www.parseerror.com/blog/select-*-is-evil . There are exceptions to this rule (like every rule) but it in generally using select * is a common way to incur a software maintenance debt. It also can force the db to retrieve more data than needed, and in doing, so miss out on query optimisations to get your data quicker (if you don't actually need all columns).
