I have a particular coloumn in my table named "STATUS" . This is a numeric field with values ranging as 10,20,30,40,50.

I donot want this coloumn either in ascending or descending order.
I want it in the following order ( 30, 10, 50, 20, 40). How shall i specify it in my order by clause?

you can use a CASE to set another selected column/:Host-variable based on your STATUS and ORDER BY the CASEd column.

or

using case, change the status from 30 to 'A 30', 10 to 'B 10' etc...

Catherine,

Try this untested sql

Code:

SELECT Z.STATUS                         
  FROM (SELECT STATUS                   
              ,CASE STATUS               
                    WHEN 30 THEN 1       
                    WHEN 10 THEN 2       
                    WHEN 50 THEN 3       
                    WHEN 20 THEN 4       
                    WHEN 40 THEN 5       
                    ELSE 9 END  AS SR_NO
         FROM Table) Z                     
 ORDER BY SR_NO                         
 ;     


Hope this helps...

Cheers

Kolusu
