Introduction to regular expressions ...

cd,

Excellent, thankyou very much for sharing your expertise.

Could I please point you to 432368 to get your insight on why I'm having a problem with Apex using a regex that works OK in a non-Apex environment?

Many thanks,

john

And, as I mentioned in another thread, HJR's www.dizwell.com is another good option.

This is just the sort of information I was looking for, and I think you should submit it to oracle magazine. I'm sure they'll like it, but they may ask for some amendments.

Thank you. However I'm afraid Oracle Magazine won't take my article because they state that they will only publish articles that haven't been published anywhere else - and posting it here probably counts as publishing.

I was trying to use regexp_substr function to retrieve the email domain (eg. yahoo.co.in for [email protected])...but all I could get to was

"select regexp_substr('my email is [email protected]','@[^[:space:]]*',1,1) str from dual;" -- @yahoo.co.in

I am missing something here....Is there any ways that I could get what I just wanted.....Using trim function to remove the leading '@' is one way....

Can the regular expression do this for this situation?

Thanks.

Just some quick answers from my side, with REGEXP_SUBSTR and REGEXP_REPLACE:

WITH t AS (SELECT 'my email is [email protected]' col1
             FROM dual
          )
SELECT t.col1
     , LTRIM(REGEXP_SUBSTR(t.col1, '@[^[:space:]]+'), '@') solution_1
     , REGEXP_REPLACE(t.col1, '@([^[:space:]]+)|.', '\1') solution_2
  FROM t
;    

OL1                        SOLUTION_1                  SOLUTION_2
-------------------------- --------------------------- --------------------
y email is [email protected] yahoo.co.in                 yahoo.co.in
