your ideasYou should be able to do this. However, you must make sure that there are database links created on db3 for db1 and db2. Also, the user for db1 database link (call him db1user) must have select rights on table t2 and the user for database link db2 (call him db2user) must have create table rights on db2.
I don't have multiple database available at home so can't give you exact sample. However, the general solution is along the lines mentioned below.
- Create a database link for db1 while logged into db3.
"create database link db1link connect to db1user identified by passwd using db1serviceName;" where db1user is the user on db1, passwd is the user's password and db1serviceName is the tnsnames service name for db1 (check tnsnames.ora on db3 machine).
- Same way, create a database link for db2 while logged into db3.
"create database link db2link connect to db2user identified by passwd using db2serviceName;"
- Now, create the actual table.
"create table t1@db2link as select * from t2@db1link"
Hope that helps. Let me know if that worked for you.
