I am sorry. I am trying to groupby and not orderby. I want to select from 2 tables and groupby the id of one table. This works fine in sqllight but throws an error on postgresql. Massimo suggested that I add the id of the second table using "|". However, then I can't get the result I need, which is grouping by the id of the first table only. I hope this makes sense.
