Comment

-- Use HAVING instead of WHERE when you want to use filtering on aggregation 
-- nonagg_col = the columns that are not aggregated
-- agg_col = the columns that are being aggregated with agg funcs
-- agg funcs = count, sum, avg, min, max
SELECT nonagg_col1, nonagg_col2,  COUNT(agg_col) 
FROM table_name
WHERE nonagg_col1 IN ('A','B')
GROUP BY nonagg_col1, nonagg_col2
HAVING COUNT(agg_col) >10
ORDER BY nonagg_col2 DESC
LIMIT 5;

HAVING clause we can use when, WHERE keyword cannot be used with aggregate functions(Count,Sum,Avg,Min,Max)

HAVING COUNT(CustomerID) > 5;

what is having clause in sql

Comment

HAVING clause in SQL is used to
filter records in combination
with the GROUP BY clause. It is
different from WHERE, since 
WHERE clause cannot filter 
aggregated records. HAVING is a column
operation.

Select department_id, Min (Salary)
From Employees
Group By Department_id
Having MIN (salary) < 3500;
