Depending on the volume, you may want to play with different options to see
which works best for you. We've got instances where millions of rows are being
checked and I found that using 'i' for case insensitivity was actually slower
than using UPPER().

Hi All,
what regular expression would you suggest to get all ORA- errors (with from 1
to 5 numbers)
out of some text like this:
' ORA-00001 ora-0002 ora ora-003 aasdlkja alksdj alksdj laskdj
ORA-04 aaaa a a a aora-5 '
I am trying to figure out how to use
regexp_replace to replace all characters around ora-... errors to get output:
'ORA-00001 ora-0002 ora-003 ORA-04 ora-5'
but can't find appropriate expression so far:
with s1 as (select ' ORA-00001 ora-0002 ora ora-003 aasdlkja alksdj
alksdj laskdj ORA-04 aaaa a a a aora-5 ' s from dual)
select regexp_replace(s, '...', '...', 1, 0, 'i') from s1
/
