SQL syntax error

Hi everybody,

I need some help with a spiceworks SQL report "Ticket Workload (30d)"

The reports gives me an error when saving: Invalid SQL - no such column: tickets.time_spent

on this link http://community.spiceworks.com/help/Potential_Reporting_SQL_Errorsthere is a suggestion to do the following:

tickets.time_spent

SELECT tickets.time_spent FROM tickets

SELECT COALESCE(SUM(ticket_work.time_spent), 0) as time_spent

FROM tickets LEFT OUTER JOIN ticket_work ON ticket_work.ticket_id = tickets.id

GROUP BY tickets.id

What should I change in the SQL code? any help would be appreciated.

This is the original code of the report:

select'IT-Maintenance or Projects'as"Category",

count(tickets.id)as"Tickets",

Cast(round(avg((julianday(tickets.closed_at)-julianday(tickets.created_at))),2)astext)as"Avg Days Open",

...
