Hi,

I have following sql query:

with texttab as
(
SELECT 
  ROOT_CAUSE as text
from cust_bug_data where ROOT_CAUSE is not NULL
)
SELECT regexp_substr(text,'\#[a-z0-9_]+',1,level,'i') as tag
FROM texttab
CONNECT BY regexp_substr(text,'\#[a-z0-9_]+',1,level,'i') IS NOT NULL


This query returns all the keyword prefixed with # from ROOT_CAUSE column in my cust_bug_data table.
currently output is like as follows:
#test
#timing
#test
#timing
#code


I want # to be removed from the output.

So I am looking my output to be like:
test
timing
test
timing
code


Please advice me on how to do this.

Any reason you can't use:

replace(text, '#')


?
