SQL query help. Given the (fictional but equivalent) table disk_status = computer_id:int, disk_id:int, datetime:datetime, temperature:float, rpm:int, I need to provide a table of disk status for a given computer_id, without knowing in advance how many disks there are. So if there were two disks for a particular computer, the result would have the header: datetime, disk_1_temperature, disk_1_rpm, disk_2_temperature, disk_2_rpm, disk_2_rpm [more inside]
