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().

Subject: regular expression to get ORA- errors out of text
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
/
