How to use hash join hint in Oracle?
Could you please elaborate on how to effectively utilize the hash join hint in Oracle? As a seasoned database administrator, I'm familiar with the basics of SQL optimization but I'm curious about the specific scenarios where employing a hash join hint could significantly enhance query performance. Could you provide some practical examples and explain the nuances of this advanced technique, including potential drawbacks or scenarios where it might not be the most suitable choice? Additionally, how does one determine if a hash join hint is indeed the right approach for a given query?
