EP 8 - Advanced Aggregates in SQL
In this step-by-step video tutorial, you will learn some more advanced SQL aggregation concepts by using the GROUP BY, HAVING, and WHERE clauses!
Queries:
1) Pull aggregate information with the GROUP BY clause: SELECT column1, column2, COUNT(column3) FROM table GROUP BY column1, column2
2) Use the HAVING clause to filter your aggregation: SELECT column1, COUNT(column2) FROM table GROUP BY column1 HAVING COUNT(column2) = 5
3) Use WHERE and HAVING clauses in the same query: SELECT column1, COUNT(column2) FROM table WHERE column1 = 3 GROUP BY column1 HAVING COUNT(column2) = 5
