SUM()
The SUM() aggregate function takes the name of a column as an argument and returns the sum of all the value in that column.
Syntax
SELECT SUM(column_name)FROM table_name;
Example
For instance, suppose there’s a transactions table with the following values:
| date | amount |
|---|---|
| 2023-01-30 | 2.75 |
| 2023-01-31 | 6.00 |
| 2023-01-31 | 4.20 |
The given query will return the sum of all values from the amount column:
SELECT SUM(amount)FROM transactions;
The result would be:
| SUM(amount) |
|---|
| 12.95 |
