Oracle中的SUM用法讲解
Sure, I can help you with that. The SUM function in Oracle is used to calculate the sum of all values in a selected column. The syntax for the function is:
SUM(column_name)
For example, if you have a table named "Orders" with a column named "Amount" and you want to calculate the total amount of all orders, you can use the following SQL statement:
SELECT SUM(Amount) FROM Orders;
I hope this helps! Let me know if you have any other questions.
