On 7.3, I get 1 as a result.

Is it a CCSID issue? I'm running 37.

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
