We are running on 7.2 so perhaps...
Interestingly, it runs if I remove the ^ and $ from the regex.
But obviously then it will return 2 for strings like '00a00' rather than 0...

Your SQL statement works nicely and returns 1 on our 7.3 box. Maybe there is a PTF missing?

Betreff: Regex not working with regexp_count
Hi,
I have a simple regex I want to use to validate mobile phone numbers:
‘^\+?\d+$' – this checks for 0 or 1 ‘+’ followed by any amount of digits
When I test this on various regex websites (regextester.com for example) it seems to do the job perfectly.
But when I plug this into my interactive SQL session like so:
select regexp_count('07777','^\+?\d+$') from SYSIBM/SYSDUMMY1
I get the following error:
1 -- The external program or service program returned SQLSTATE 2201S. The
text message returned from the program is: ????REGEXP_COUNT????^\+?\d+$ .
This SQLSTATE is “Invalid regular expression pattern.”
I’m sure I’m doing something wrong but unsure what. I have read the IBM documentation and my syntax seems to be valid (?)
Cheers
