The rules for number of changes that can be made within a single ALTER TABLE statement are as follows:
  • Only one change can be made per column per ALTER TABLE statement.
  • Only one CHECK alteration is permitted per ALTER TABLE statement, and you cannot mix CHECK and non-CHECK alterations on the same table for the same ALTER TABLE statement.
