Abstract
Techniques are described herein for altering the datatype of a column without having to immediately migrate the data items that currently reside in the column. In one embodiment, the alteration is performed without migration by creating a new column having the desired datatype while retaining the old column. Instead of migrating the data items from to the new column at the time the column is altered, the items remain in the original column until the items are updated.
