Home -> Community -> Mailing Lists -> Oracle-L -> RE: SQL Question
Another nice idea !
I will pass it on.
Looks like instr/substr can not be avoided... :(
Thanks.

Would they allow you to create a view with substr/instr and then just code
off
of the view?

Kirti - We have a denormalized table like this in one database. An excellent moral lesson for those who doubt the wisdom of normalization.
My first choice would be to lobby to redesign this table. The longer it remains and the more programs are built around this design, the more painful the eventual redesign will be.
My second choice would be something along the lines of a shadow table to move all the records periodically for reporting. If you need to search on these fields, you could create a function-based index on each column. One idea that occurs to me that I haven't tested would be whether you could write a stored procedure that would parse the field and return the columns. This would be usable by any utility that could execute a PL/SQL procedure.
Kirti - you have my sympathy.

Thanks.
Substr/instr was rejected because it was a bit difficult to read the code.
Also, they wanted to extract the fields in their own column headings (new requirement). So 'replace' may not fly much !!

What about
select commission_id, replace(com_text_msg,'~',chr(9)) from tab1
which would work if going to a tab separated file for something like excel.
Whats wrong with substr/instr?

I need some help...
The database table has following structure.
commision_id number
com_text_msg varchar2(500)
The second column contains data fields that are delimited by ~ and delimiter's position varies. But there are only eight data fields in the column.
Is there a way in SQL, other than substr/instr combinations, to extract each data field to report?
Thanks.
