sql advanced interview questions offset clause display skipped rows only

In an advanced SQL interview, candidates may be asked about using the OFFSET clause to selectively display skipped rows. The question assesses the ability to strategize beyond syntax, requiring candidates to discuss the conceptual approach. They should articulate the utilization of the OFFSET clause to skip specific rows and then employ a suitable technique, like using NOT IN, to exclusively showcase the skipped rows. This demonstrates proficiency in SQL thinking, emphasizing logical structuring of queries to achieve desired outcomes in complex scenarios.
