What is Data Processing and Analysis Guide about?
The difference between the HAVING and WHERE clauses is when each is applied during query processing. The WHERE clause is applied earlier, before rows are grouped, and can use indexes to filter rows. HAVING is applied later, after rows have been grouped and aggregate functions have been computed, and is useful for filtering based on aggregates or columns only available after grouping.
