I am trying to make this a trigger, but so fat this is all I've got:

```
CREATE TRIGGER trg_SetDateToNextBusinessDay
ON dbo.Orders
AFTER INSERT
AS
    UPDATE dbo.Orders
    SET OrderDateTime = {next  day that is Monday-Friday, 8:00 am}
    WHERE OrderDateTime {is after 4:00} OR OrderDateTime {is on a saturday or sunday}

```

What is the easiest way to do this?
