Lisa,
you are right ... on both counts ... but look at it this way ... if you use
the LIMIT clause, when you go for fetch next set of data, you have to figure
out which rows to skip, so there you have more logic to work with.
As for the amount of memory, you are right too, but then again it matters a
lot how you design the pl/sql table. Also if one is worried about space
utilization, look at PRAGMA SEREALLY_REUSABLE. This pragma can be
incorporated into package spec, so once package execution is complete, the
data space is released to SGA immediately (more details are in the manual),
it is reallocated when package is invoked. Previously pl/sql table allocated
memory was wither help or if you specify FUUM
(DBMS_SESSION.FREE_UNUSED_USER_MEMORY) the memory was released BUT only for
other pl/sql table use until your session disconnects.
