I need to get the latter characters from a field and compare it with the field value in another table. What is the syntax to strip the characters that I don't need and use only the characters I do need in a query?

This is what I have:

select count(*) from dc_rule
where Doc_I in
(select pdf from holdings
  where pub_date >='01-JAN-10'
              and pub_date<='31-DEC-10');

dc_rule field has the following value:

RDBAFM_ORA10://cpia_lib/CPIA-1995-0525

I don't want to remove any characters. I just want to capture a portion of the value of the field and compare it to another field. For example I only want CPIA-1995-0525 in the above sample. Is that possible? If so How would I do this?

parsing is all about rules, you haven't specified how we identify which piece of the string you would want.

So I'll take a guess.

You want the substring following the last "/"  character.

try this...


regexp_substr(dc_rule,'[^/]+$')

if the rule for extracting the piece you want is something else, please specify and I'll adjust accordingly

I basically want to exclude RDBAFM_ORA10://cpia_lib/

that's even simpler

REPLACE(dc_rule, 'RDBAFM_ORA10://cpia_lib/')
