The SQLite HAVING clause is used to specify conditions that filter which group results appear in the final results. The WHERE clause places conditions on the selected columns, whereas the HAVING clause places conditions on groups created by the GROUP BY clause.
The position of HAVING clause in a SELECT query:
SELECT FROM WHERE GROUP BY HAVING ORDER BY
Syntax:
SELECT column1, column2 FROM table1, table2 WHERE [ conditions ] GROUP BY column1, column2 HAVING [ conditions ] ORDER BY column1, column2
Example:
Let's take an example to demonstrate HAVING Clause. We have a table named "STUDENT", having the following data:
Example1:
Display all records where name count is less than 2:
SELECT * FROM STUDENT GROUP BY NAME HAVING COUNT(NAME) < 2;
Output:
Example2:
Display all records where name count is greater than 2:
SELECT * FROM STUDENT GROUP BY NAME HAVING COUNT(NAME) > 2;
Output:
