Hi Experts -
I am trying to parse the following string
my input
(KEYWORD . . . . . CodeWord.  xyz8397G3 (54321) AND 7586806(06789))
My output should be
KEYWORD . . . . . someString. xyz8397G3 (54321) AND 7586806(06789)

I am trying to retrieve every thing between starting parenthesis and ending parenthesis.

regards

I don't understand your example, but to satisfy the description...
"I am trying to retrieve every thing between starting parenthesis and ending parenthesis."


don't use regexp_substr  use regexp_replace instead


regexp_replace(your_string_here,'(^\()(.*)(\)$)','\2')

I will close it. Can I ask you question before that. If you have some time to spare, can you please explain the solution

(KEYWORD . . . . . CodeWord.  xyz8397G3 (54321) AND 7586806(06789))

regexp_replace(your_string_here,'(^\()(.*)(\)$)','\2')

What I would like to know, where the outer parenthesis are being replace in this logic

Regards

sure,
the expression is in 3 parts...

1 - (^\()   - which means start with open parentheses
2 -(.*)   - which means anything
3- (\)$) - which means ends with parentheses


the \2 replacement means replace the entire expression with the 2nd part of the expression
so, it's not so much that the parentheses are being replaced with something rather they are not included
