Two columns in having clause

Can we compare values of two columns in a HAVING clause?

Hi, welcome to the forums.
Do you have a specific example?

Remember, HAVING filters groups (and is used with GROUP BY) WHERE filters rows. You can’t use WHERE with aggregates, but you can use HAVING with aggregates. You can use the WHERE clause with HAVING as well.

Example, like you can assume that a comparison has to be made on the column values of result of GROUP BY.
