Bitcoin and me (Hal Finney)
I thought I'd write about the last four years, an eventful time for Bitcoin and
me.
For those who don't know me, I'm Hal Finney. I got my start in crypto working on
an early version of PGP, working closely with Phil Zimmermann. When Phil decided
to start PGP Corporation, I was one of the first hires. I would work on PGP
until my retirement. At the same time, I got involved with the Cypherpunks. I
ran the first cryptographically based anonymous remailer, among other
activities.

Triggers

  • The trigger body is a PL/SQL block in which you can issue both SQL and PL/SQL statements from the trigger body. You can also call a stored procedure or a Java procedure from the trigger body. You can also invoce a procedure developed using object-oriented languages, such as C.

  • USER_PROCEDURES and USER_OBJECTS views - object status is in USER_OBJECTS
