Re: Which is faster at string manipulation and searching? RPG or SQL

Why do you think SQL relies on Java stack to parse regular expressions? It requires the International Components for Unicode, which has both Java and C
interfaces. Since DB2 uses C in most places, I would expect it to use C for
ICU components as well. Is there a place that tells us it uses the Java interface?

I concur with this ... I recently started using the SQL regex functions for
string analysis & manipulation... if it was invoking Java functionality, I would
have noticed the JVM startup penalty.

When invoked from a SQL RPG program, it's very fast.
