SQL Interview Question and Answers | SQL Query To Find Total Purchase Amount of All The Orders

Description:
To find the total purchase amount of all orders, you can use the following SQL query, assuming you have a table named "Orders" with a column named "PurchaseAmount" that contains the purchase amounts:

```sql
SELECT SUM(PurchaseAmount) AS TotalPurchaseAmount
FROM Orders;
```

In this query:

- `Orders` should be replaced with the actual name of your table that contains the order data.
- `PurchaseAmount` should be replaced with the actual name of the column that contains the purchase amounts.

This query uses the `SUM()` function to calculate the sum of all the purchase amounts in the "Orders" table. The result will be the total purchase amount of all orders.
