For example, we might want to see only the stores with sales over $1,500. Instead of using the WHERE clause in the SQL statement, though, we need to use the HAVING clause, which is reserved for aggregate functions. The HAVING clause is typically placed near the end of the SQL statement, and a SQL statement with the HAVING clause may or may not include the GROUP BY clause. The syntax for HAVING is,
SELECT "column_name1", SUM("column_name2")
FROM "table_name"
GROUP BY "column_name1"
HAVING (arithmetic function condition)
Note: the GROUP BY clause is optional.
In our example, table Store_Information.
Table Store_Information
SELECT "column_name1", SUM("column_name2")
FROM "table_name"
GROUP BY "column_name1"
HAVING (arithmetic function condition)
Note: the GROUP BY clause is optional.
In our example, table Store_Information.
Table Store_Information
| store_name | Sales | Date |
| Los Angeles | $1500 | Jan-05-1999 |
| San Diego | $250 | Jan-07-1999 |
| Los Angeles | $300 | Jan-08-1999 |
| Boston | $700 | Jan-08-1999 |
we would type,
SELECT store_name, SUM(sales)
FROM Store_Information
GROUP BY store_name
HAVING SUM(sales) > 1500
Results:-
SELECT store_name, SUM(sales)
FROM Store_Information
GROUP BY store_name
HAVING SUM(sales) > 1500
Results:-
| Los Angeles | $1800 |
