I want to create an ECT with Create/Update method using SPD.
The dropdown choices should be also from another table in the database.
How can I achieve this?

Hi,
It is not supported to create External Content Type with a dropdown column by OOTB.
For a workaround, you can use Custom Field Controls and jQuery to add Drop Down List to External List Form.
Please take a look at this article SP 2010: Customizing the forms for External Lists (BCS) in SharePoint 2010 by using Custom Field Controls and jQuery
