Why does Oracle not enforce a predicate when querying over a database link?

in SQL Performance (MOSC) 5 commentsAnswered

Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production   

                                         Version 19.18.0.0.0

See the attachment. When querying from one database into another, the predicate is ignored on the target, then filtered at the local database. Returning MILLIONS of records that will be filtered.


Howdy, Stranger!
