Question

How can I use having with multiple clauses ?

Like that one but this doesn’t work

HAVING COUNT(t2.ID) > 0, COUNT(t3.ID) > 0

Thanks

Answer 1

you have to add AND or OR operator between the conditions.

SELECT * 
FROM tableName
HAVING COUNT(colA) > 4 AND MAX(colB) = 3

you could also apply grouping.

SELECT * 
FROM tableName
HAVING (COUNT(colA) > 4 AND MAX(colB) = 3) OR 
       SUM(colC) > 100
