Hello,

My program needs to connect to two databases and make operations in both databases:

Quote:
connect to db1;
connect to db2;

select from table in db1;
update table in db2;


i would like to know whether it's possible, and how to do it ? how to specify for each query the database connection to use?

please note that I can't use dblinks as i don't have enough access rights and privileges on neither of the databases.

thanks you for your replies.
