Never used Pro*C, though did work with Pro*Pascal for a few years.

The fact a single record will be retrieved is irrelevant to the implementation, which requires a CURSOR etc. If you want to assume there is always 1 record, and you can avoid the LOOP, you should by all means do so.
However you probably are aware that 'assume' is an acronym for 'I made an ass out of me and you'.
I would probably judge such code as ready for the garbage bin.
