Hello Srikkanth,
The query you posted cannot return the inventory_item column because that column isn't part of you GROUP BY clause.
If you need to see the inventory_item column, you should either include it in your GROUP BY clause (but I doubt that's the right thing to do in this case) or, you need to apply an aggregation function to the inventory_item column, such as MAX or MIN (this may be appropriate in this case but, without seeing any data, can't really tell).
The GROUP BY limits the fields you can select to be either, included in the GROUP BY clause or, arguments of an aggregation function whose result is driven by the GROUP BY clause. In any other case, you'll get message complaining about the field not being part of a group by group.
HTH,
John.
P.S: put code (like the select you posted) and data enclosed in [ code ] <your code here> [ / code ]
(without the spaces), that will format the code nicely, like this
nicely formatted code herewhich makes it much easier to understand.
