Home -> Community -> Mailing Lists -> Oracle-L -> RE: simple question on DDL
Consistency is the key too.... imagine what would happen if I dropped a
column or changed it's definition, while a SQL statement or PL/SQL package
was executing. The data that was updated before the change may well be very
different in nature than the data after the change....
Borrowing from Ghostbusters if I may:
Dr. DBA: This database is about to face a disaster of biblical proportions. Hapless Manager: What do you mean, "biblical?" Sr. DBA Lead: We mean real wrath-of-God type stuff. Plagues, darkness-- Another DBA: The dead rising from the grave!
Sr. DBA: Forty years of darkness! Earthquakes, volcanoes-- Dr. DBA: Riots in the streets, dogs and cats living together, mass hysteria Manager: So, it's Ok to cut the DBA budget then?

Well look at it this way, besides creating/modifying/dropping the object
that you want your also performing a number of updated/inserts/deletes from
the
data dictionary. Those data dictionary tables are just that, tables. Now
imagine what a mess would be created if you performed a DDL statement and
then
rolled back the data dictionary updates? These MUST be completed as a
single
autonomous transaction, so Oracle does you a favor and performs an implicit
commit. Same thing with any other DBMS I've been associated with.
