MYSQL如何按ID对条目进行分组并创建具有分组条目的列？

Question

This is a newbie question, just started studying MySQL. Basically, what I want to do is the following In the well-know ecommerce db exist several tables that relate to orders and their cost.

I have a table that looks like this

OrderID TotalSum
10248   60
10248   140
10248   120
10249   64.26
10249   480
10250   250
10250   420
10250   225

I want to group identical OrderID and have summed the TotalSum for them and store it in separate table. I run the following query

SELECT SUM(TotalSum), OrderID FROM orders_data GROUP BY OrderID;

and get what I want.

The problem is for some reason (mainly mine stupidity) I can't have the result stored as separate table. What is right query for this?

Answer 1

If you want to create a new table , you can use this:

CREATE TABLE anothertbl AS SELECT SUM(TotalSum) as TotalSum, OrderID 
FROM orders_data GROUP BY OrderID;

Answer 2

Try this

INSERT INTO `your_table` (`column_name_that_holds_OrderIDs`, `column_name_that_holds_SUMs`)
SELECT `OrderID`, SUM(TotalSum) as `TheSum`,  FROM orders_data GROUP BY OrderID;
