changing default values

How can i change the default value of a column? I already have a column
named DateOfRental but I want to alter it so that it has default value
getdate()

Thanks
David

1. Use sp_help to get the current name of the constraint

exec sp_help MyTable

2. Drop the constraint

alter table MyTable drop constraint <Constraint name goes here
3. Add a new constraint

alter table t1 add constraint DFT_DateOfRental default getdate() for
DateOfRental

Simon|||Will try that, thanks Simon

If there is no constraint, you should not have to drop it.
