您好Aimable baixista，

Hi Aimable baixista,

单程：   " SELECT SUM（Amount）AS Sum_amount FROM Transactions_tbl [WHERE ...]"

One way:   "SELECT SUM(Amount) AS Sum_amount FROM Transactions_tbl [WHERE ...]"

您可以填写自己的特定名称，并在必要时添加WHERE子句。

You can fill in your own specific names, and if necessary add a WHERE clause.

Imb。
