DELETE vs TRUNCATE vs DROP ❓
Looks similar. Works very differently.

DELETE → Removes rows, keeps control.
TRUNCATE → Clears data in one shot.
DROP → Deletes everything. No recovery.

If you understand this, you’re already ahead of most beginners in SQL.

Save this. Share it. And use it in your next interview.

RANK or DENSE_RANK?
Same-looking output. Very different meaning.
And yes, choosing the wrong one can cost you points in interviews and clarity in real reports.

• how ties are handled
• where gaps come from
• when RANK is correct
• when DENSE_RANK is the safer choice
