Hello everybody,
I have a table like this one: id value order_field 1 10 3 2 12 4 3 10 1 4 5 8 5 12 2 What I want to do, is to do something like SLECT DISTINCT ON (my_table.value) my_table.id, my_table.value, my_table.order_field FROM my_table ORDER BY order_field Hence selecting rows with distinct values, but primarily ordered by order_field, instead of value, which is requires by DISTINCT ON. The result in this case should be: id value order_field 3 10 1 5 12 2 4 5 8 How do I do this? I do need order_field in the select list to use it in the ORDER statement, which is why - as far as I can see - GROUP BY and SELECT DISTINCT are useless. Did I miss out on something? Thank you in advance
