Via Steven Feuerstein I was asked to try and give advice concerning fastest way to parse CSV data in PL/SQL. The case was that they had a different database that could be setup to deliver data as a webservice serving either CSV, XML or JSON, and they wished to let their APEX application use PL/SQL to retrieve data from that other database via such webservices. They were not yet on 126.96.36.199.0 so they did not have JSON_TABLE, and they seemed to find that do-it-yourself parsing of CSV data was the fastest. Did we have any idea of a faster way?
