For testing, I've decided to use the mysql command line interface and I have
one last question. How would I take take sums of
two columns such as JobFiles and JobBytes
[18:13:04 root@jenna:~]# mysql -u root -pxxxxx

20 rows in set (0.01 sec)
If you want that same list, and add the sums at the end, I don't believe
it is possible with MySQL client. It would be easy with Oracle SQL*Plus,
but not with MySQL client.
A simple query will return those
SELECT SUM(JobFiles) AS JobFilesSum, SUM(JobBytes) AS JobBytesSum
FROM Job ;
but that is not much of interest, I guess.
