Description

Changing the type of a virtual column will not affect the format of the clustered index. It may imply DROP INDEX and ADD INDEX for any indexes that are defined on the virtual column. If such indexes are to remain after the ALTER TABLE operation, then changing the virtual column type obviously cannot be an instantaneous operation.
