I have a local (read and write) sqlite database and a remote (read-only) oracle database. I use ODBC to access both DBs (I use an application to access the DBs by ODBC and query as such: EXECUTE-QUERY SQLITE “SELECT …” or EXECUTE-QUERY ORACLE “SELECT …”) . I tried searching the net for a way to be able to perform one query joining tables from the 2 databases, but all I find is how to create a database link from oracle to other DBs but that doesn’t help me because I have no write priviledges for the Orcale DB so creations of database links, databases, tables, views are not allowed in ORACLE, all I can do is query there. Is there an efficient way to do this with the restraints that I have?

Finally I installed Oracle express edition and created a database link to the other (read-only) oracle database. That worked great.
