I have the following REGEX example that works in my testing tools (java) but not in Oracle
SELECT REGEXP_SUBSTR ('conn-conf-set:ttv|hsia,up-speed-kbps:5000,dn-speed-kbps:17000', '(?:up-speed-kbps:)([\d]+)')
AS upstream_rate
FROM DUAL
I just want 5000 returned, I can get it return up-speed-kbps:5000 if I use 'up-speed-kbps:(\d+)'
