I have added a field for Daylogged as Date, I have a field called DateLogged as datetime. I have updated all of the Daylogged fields by casting the Datelogged as Date field. I am having trouble setting a default value for the Daylogged field to equal the datelogged field. I have tried cast(datelogged as date) to no avail. Any suggestions would be appreciated. Thanks

Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

A default constraint can be applied to a column to give it a default value when a row is created. The default value is generally either a literal value, such as a specific number or string, or a reference to a function.


create table webfred(id int identity(1,1), Daylogged Date default getdate(), Datelogged datetime)
insert webfred(Datelogged) select getdate()

select * from webfred

A clarification is needed on my original post: The datelogged field is required and always has the time associated with it, the purpose for the daylogged field is to provide a means of indexing by day as opposed to datetime to improve performance, it is almost a calculated field.

Why can't it be made a calculated field?
