Dear Forum,

Could you please advise why Teradata Alter table statements for adding new columns takes lot of time for Large tables.

I think this is normal if we are giving some default values where it as to rewrite the entire table.

Will the same process happens even if there are no default values while adding columns?

Thanks & Regards,
