Hello! How are you? Can you please provide me with a list of all department IDs, department names, and their respective years of creation?

Excellent! Can you filter this list to include only the rows that contain the most common (most frequently occurring) year of creation?

SELECT Department_ID , Name , Creation FROM department WHERE creation = ( SELECT creation FROM department GROUP BY creation ORDER BY COUNT( * ) DESC LIMIT 1 );
