Title: RE: collections/PLSQL tables

Raj,

Well, you can limit the number of rows BULK COLLECT will return with the LIMIT keyword.  Wouldn't that take care of the performance problem you refer to? And isn't it affected by the amount of free memory on the host?  For insteance,  there's very little "free" memory and you bulk collect 1000 rows and the host starts paging. 

Any comments?

    Bill,

    If you are or will be retrieving more than say 10000 rows, I'd say do not
    use BULK COLLECT (performance goes down)... instead use a pl/sql table of
    records. But I'd say even with the inconvenience of specifying a separate
    collection for each column, use for BULK BINDS for INSERT/UPDATE/DELETE is
    worth the effort, as it really speeds up the processing.

    Oracle recommends that for faster performance, instead of using a TABLE of
    RECORDS, use a RECORD of TABLES. The speed benefit is due to the way data
    elements storage technique implemented for these two types.

    According to rumors, 9i is supposed to offer more, but I haven't got time
    right now to test it out.
