If you have read my previous tip about Oracle XML API
You would learn to use XML API as nice quick’n’dirty replacement to tons of decode functions.
In this challenge I got on Oracle 9i (yes they still exist in production 2013).
- We have a string such as ‘123#124#122′, we need to split the different values into record , sort them and map them from a Value-key pair table in an Oralce 9i database.
- And for reasons of implementation it has to be done in pure SQL, not PL/SQL.
- and it is best to avoid creating any stored procedures or functions.
A more elaborate description of the problem : Splitting a delimited text with Oracle SQL into records, and sorting them out.
This is a real challenge in the production environment I’m working in.
