Conditional parsing on sort clause

Conditional parsing on sort clause

Conditional parsing on sort clause

I have a two tables regarding my question.  Table 1, say INDEX, stores metadata on statements.  Table 2, say DEFINITION, defines what type of record is in INDEX.

There is a column in table INDEX where the metadata, say METADATA, is stored.  This column is a CHARACTER type.  I need to write a query that will sort table INDEX by the METADATA column and have some sort of logic to parse the sort to an INTEGER when the related column, say TYPE, in DEFINITION is equal to 'I'.

Example desired sort when METADATA is defined as an 'I' type by column TYPE in table DEFINITION:


Example normal sort:


Is there a way to add in the integer parsing of METADATA based on a related record in a different table?  Would it be possible to inject the INTEGER( ) into the ORDER BY clause based on some sort of IF statement/logic?

(Note:  This is the way our tables are designed, please don't suggest modifying the design as that is not a viable solution.  Thank you.)

Can you please share your table information?

RE: Conditional parsing on sort clause

I use this syntax


select empno
     , sex
     , salary
     , case when sex  = 'F'
            then salary * -1
            else salary
       end as sort_col     
from   employee
order by sort_col
Nonsence example, but when you replace "sex = male/female" by some kind of "debit/credit" code it suddenly makes sence :)
