Does Toad for Oracle 188.8.131.52 have Cross Connection query builder?
A question similar to this was also posted a few months ago, and the answer can be seen here:
Toad for Oracle doesn’t natively support doing cross-connection queries in Query Builder. There are some Oracle techniques (like Database Links) you can use to try to make it work in Toad for Oracle, but the Query Builder in Toad was designed to build queries within the current connection. For native support of cross-connection queries, I’d recommend taking a look at Toad Data Point.
For information about techniques you may be able to use to get it to work in Toad for Oracle, I’d recommend visiting the following Toad World post:
