SELECT sum(amount) from transactions as t2 where t2.customer_id = t1.customer_id and t2.timestamp <= t1.timestamp) |

Header results looks like this:
+-----------+-------------+--------+------------+
|
| timestamp | customer_id | amount | SELECT sum(amount) from transactions as t2 where t2.customer_id = t1.customer_id and t2.timestamp <= t1.timestamp |

FROM transactions AS t1 |
ORDER BY customer_id, timestamp) |
SELECT * from result; |
Header result looks different for the same definition.
