Query Syntax
I need to query a field(Hours) in my DB that has numeric values in each entry, However, I am not sure how to add up all of the numbers that are returned by the query? Can someone please point me to the correct tutorial or offer an example?

What is the data type of the Hours field? Are you looking for a sum of all the hours in the table or a sum for a given set of records? If the first, RajkumarGS gave you the answer. If the second, you will need to do a group by. For example, if you wanted the total hours worked by each employee, you would select employee_id, count(*) from table group by employee_id. Perhaps some sample data and the expected results might better clarify your issue.

Regarding the last sentence, I could not agree more!

Ray_Paseur,
Beleive me, if I could do that, I would. All too frequently attachments are the only way my responses will go through. I tried to initially respond in clear context and I apologize for any inconvenience. I can only say that it is extremely inconvenient for me to have to respond in this way.

Wonder why that is -- I see a comment form and it's for me to type responses into the form. Have you told EE about the issue?
When EE upgraded their site (it's been, what, about 2 years ago), I started having the problem and mentioned it a number of times, but there seemed to be no solution. It seems the problem may be with my extremely restrictive firewall.
10-4. I have no firewall. Maybe there is a way to tell your firewall to whitelist the domain?
