It has been found that regexp_count works brilliantly in Oracle.
However, it is not easy to replicate that in Postgres. The following codes have been experimented but without any luck.
select regexp_matches('My High Street', '([A-Z][a-z]+[\s])', 'g')
select regexp_matches('My High Street', '([A-Z][a-z]+[\s]*)', 'g')
County occurrences of 'My High Street' in one of the following strings:
'My High Street' 1
'' 0
'My High Street My High Street' 2
Can anyone enlighten all of us?
Regards,
David
