HAVING (EN)

Definition

HAVING is a SQL clause used to filter groups of rows created by the GROUP BY clause. Unlike the WHERE clause, which filters rows before grouping, HAVING filters groups based on aggregated values. The HAVING clause follows the GROUP BY clause in a SQL statement and can contain conditions with aggregate functions such as COUNT, SUM, AVG, MIN, or MAX. This clause is particularly useful for limiting results that meet specific criteria for aggregated data, enabling precise data analysis in complex queries.
