Example
Assume we have the following "Orders" table:
| OrderId | ProductName | OrderDate |
|---|---|---|
| 1 | Jarlsberg Cheese | 2008-11-11 13:23:44.657 |
Now we want to add 45 days to the "OrderDate", to find the payment date.
We use the following SELECT statement:
SELECT OrderId,DATEADD(day,45,OrderDate) AS OrderPayDate
FROM Orders
FROM Orders
Result:
| OrderId | OrderPayDate |
|---|---|
| 1 | 2008-12-26 13:23:44.657 |
