Steven Hawkins commented on TEIID-3125:
---------------------------------------
Unless there is good way to glean support from the databasemetadata we'll just need to
add a translator property that will show pushdown support for like_regex. We can also
look into adding the other regexp_ functions as pushdown functions.
Netezza translator - add support for the LIKE_REGEX predicate.

Project: Teiid
Issue Type: Feature Request
Components: Misc. Connectors
Reporter: Debbie Steigner
Assignee: Steven Hawkins
With version 6 of Jboss DV the Netezza translator doesn't support the LIKE_REGEX
predicate.
Netezza doesn't support regular expression by default, but with the installation of
SQL Extensions toolkit this functionality is added. After installation Netezza provide the
regular expression functions:
regexp_extract()
regexp_extract_all()
regexp_extract_all_sp()
regexp_extract_sp()
regexp_instr()
regexp_like()
regexp_match_count()
regexp_replace()
regexp_replace_sp()
IBM Netezza SQL Extensions toolkit is an optional package for IBM Netezza data warehouse
appliances.
After installing this toolkit on Netezza and requires that regular expression in JBoss DV
syntax are pushed down (delegated) to Netezza to prevent that filtering in the Jboss DV
server most be done.
So please provide a configurable option in the Netezza translator of Jboss DV by which we
can enable the LIKE_REGEX predicate for Netezza. This option when enabled will assume that
the Netezza SQL extension toolkit is installed and the function regexp_like() is
available.
