What is a remote table in Oracle? For example, are the tables in different pluggable databases but at the same container considered as remote tables?

CodePudding user response：

Generally anything that needs to be accessed via a database link is considered "remote". Pluggable databases make that a little more 'vague' in that you still need a database link to go between them, but there are clauses such as the CONTAINERS() clause which lets you span multiple pluggables and the like.
