ORDER BY Alias not working

Question

UPDATING QUESTION:

ERROR:  column \"Fruits\" does not exist

Running Postgres 7.4(Yeah we are upgrading)

Why can\'t I ORDER BY the

Answer 1

You can use ORDER BY 1 to order by the first field, which is "Fruits". The same is valid for GROUP BY

Update

For the order, instead of doing the case in the order by, create a new column in.. say.. the second position:

(CASE 
    WHEN "Fruits" = 'Apple' THEN 1 
    WHEN "Fruits" = 'Pear' THEN 2 
    WHEN "Fruits" = 'Grapes' THEN 3 
    ELSE 4 ) as Order

Then in you ORDER BY 2.
