SQLite Having Clause
The HAVING clause allows you to specify conditions to filter the grouped results that will appear in the final result.
The WHERE clause sets conditions on the selected columns, while the HAVING clause sets conditions on the groups created by the GROUP BY clause.
Syntax
Below is the position of the HAVING clause in a SELECT query:
SELECT FROM WHERE GROUP BY HAVING ORDER BY
In a query, the HAVING clause must be placed after the GROUP BY clause and before the ORDER BY clause. Below is the syntax of a SELECT statement that includes the HAVING clause:
SELECT column1, column2 FROM table1, table2 WHERE [ conditions ] GROUP BY column1, column2 HAVING [ conditions ] ORDER BY column1, column2
Example
Assume the COMPANY table has the following records:
ID NAME AGE ADDRESS SALARY ---------- ---------- ---------- ---------- ---------- 1 Paul 32 California 20000.0 2 Allen 25 Texas 15000.0 3 Teddy 23 Norway 20000.0 4 Mark 25 Rich-Mond 65000.0 5 David 27 Texas 85000.0 6 Kim 22 South-Hall 45000.0 7 James 24 Houston 10000.0 8 Paul 24 Houston 20000.0 9 James 44 Norway 5000.0 10 James 45 Texas 5000.0
Below is an example that will display all records whose name count is less than 2:
sqlite > SELECT * FROM COMPANY GROUP BY name HAVING count(name) < 2;
This will produce the following result:
ID NAME AGE ADDRESS SALARY ---------- ---------- ---------- ---------- ---------- 2 Allen 25 Texas 15000 5 David 27 Texas 85000 6 Kim 22 South-Hall 45000 4 Mark 25 Rich-Mond 65000 3 Teddy 23 Norway 20000
Below is an example that will display all records whose name count is greater than 2:
sqlite > SELECT * FROM COMPANY GROUP BY name HAVING count(name) > 2;
This will produce the following result:
ID NAME AGE ADDRESS SALARY ---------- ---------- ---------- ---------- ---------- 10 James 45 Texas 5000Other Extensions
