Kris:

There is no native way of doing this. You would need to write your own
data-access methods -- maybe a stored procedure that returns a ref-cursor.
The procedure would attempt to lock a table before performing the select.
The DML operations on the table would have to lock the same table before the
operation can proceed. 

Hope this helps

hi list, 

how can you prevent another session from selecting from the table until
your update has committed?

we have a procedure that is querying and updating the table as one
transaction. theoretically, we'd like to prevent any other session from
accessing that table.

is this possible? we cannot limit the oracle account to one session. many
sessions need to be open since this is an ecommerce database application.

we are running oracle 8.1.6 on solaris.

thanks!
kris
