Subject: sorting months according to fiscal year
MIME-Version: 1.0

Hi 
I have to  rearrange the months according to the fiscal year i.e from April
to march and use the same in the order by clause of a query.
I have written the following postgresql function for the same, but to_number
is returning an error.
Can you please tell me where i'm going wrong?
Instead of the function to_number can you suggest any other function that
will convert a particular month to its corresponding month number(ex:
april=4 or jan=1)


 CREATE FUNCTION sort_month(to_number('April','MM')) RETURNS numeric AS $$
DECLARE 

BEGIN

       CASE WHEN 4 THEN 1
            WHEN 5 THEN 2
            WHEN 6 THEN 3
            WHEN 7 THEN 4
            WHEN 8 THEN 5
            WHEN 9 THEN 6
            WHEN 10 THEN 7
            WHEN 11 THEN 8
            WHEN 12 THEN 9
            WHEN 1 THEN 10
            WHEN 2 THEN 11
            WHEN 3 THEN 12
            ELSE 0
END;


$$ LANGUAGE plpgsql;
