Ok, thank you for the clarification. Does adding the ".first" extention
to the command get a specific row? How would I be able to get a single
row if it wasn't necessarily the first. I know you can do it with a for
loop, but how would do it otherwise?
I assume that the issue with Release_Date would be the same issue with
version_id field in the userSoftware table. Is there a way for me to get
the actual release_date stored in userSoftware instead of the id number,
as i already have that stored.
