where Doc_I in
(select pdf from holdings
where pub_date >='01-JAN-10'
dc_rule field has the following value:
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?
