Perhaps it is better to move away from the DBI fetch_hash method and go back
to using hardcoded instance variables for example

@projectCode = @data['prj_id']
@projectName = @data['prj_name']

def projectName=(val)
	@projectName = val if val
	return @projectName
end

It's a runtime error (the most common one I see).
Apparently @data has the value nil when you
try to apply [] to it...
