FAQ: RANK in PostgreSQL
When should I use RANK() instead of ROW_NUMBER()?
Use RANK()
when you need to assign the same rank to tied rows, leaving gaps in ranking, while ROW_NUMBER()
gives every row a unique number without gaps.
Does RANK() require PARTITION BY?
No. PARTITION BY
is optional. Use it to create rank groups; omit it to rank the entire result set.
What happens if there are duplicate values in ORDER BY?
Rows with the same order value receive the same rank, and the next rank(s) will be skipped accordingly, following the SQL standard.
