Hi .. Im trying (as im a beginner) to join a lot of tables and sum one of the fields in one of the tables. See attached.
Im trying to display a record set that sums the amount of hours (tbl unit_time.hours) that a person (tbl personnel.personID) worked on a single task (tbl t_persontask.taskID). Ive had a go but the result set shows the hours worked , not summed, but also repeats the taskID in a repeat region. Im stuck.
I am using this ...
SELECT t_persontask.PersonID, personnel.*, tasking.*, customer.*, system_set.*
FROM personnel INNER JOIN (((tasking INNER JOIN t_persontask ON tasking.taskID = t_persontask.taskID) INNER JOIN system_set ON tasking.sys_setID = system_set.sys_setID) INNER JOIN customer ON tasking.customerID = customer.customerID) ON personnel.PersonID = t_persontask.personID
ORDER BY taskref DESC
