On the surface, the changes to PL/SQL look rather minor, but there is some seriously cool stuff in there. I originally intended to write a single article, but some sections got too big so I thought it was worth sectioning them out into separate articles.
- PL/SQL New Features and Enhancements in Oracle Database 11g Release 1
- Cross-Session PL/SQL Function Result Cache
- PL/SQL Hierarchical Profiler
- Trigger Enhancements in Oracle Database 11g Release 1
As usual, I’ve tried to keep the explanations brief and include cut & paste examples.
There are a couple more things I might add, but I’m not sure if they are too niche. I’ll see what I think over the next couple of days.
Cheers

I raised an enhancement request during the beta phase to be able to use mixed notation with standard functions too
select regexp_substr(’a-b-c-d-e’,'(.)-(.)-(.)-(.)-(.)’,1,1,null,3) from dual;
R

c
unfortunately, the following does not work
select regexp_substr(’a-b-c-d-e’,'(.)-(.)-(.)-(.)-(.)’,subexpression=>3) from dual;
select regexp_substr(’a-b-c-d-e’,'(.)-(.)-(.)-(.)-(.)’,subexpression=>3) from dual
*
ERROR at line 1:
ORA-00907: missing right parenthesis
and the workaround to use full qualification have the side effect of not recognizing the max length of
select sys.standard.regexp_substr(’a-b-c-d-e’,'(.)-(.)-(.)-(.)-(.)’,subexpression=>3) from dual;
SYS.STANDARD.REGEXP_SUBSTR(’A-B-C-D-E’,'(.)-(.)-(.)-(.)-(.)’,SUBEXPRESSION=>3)
