Database systems, including Oracle

Database systems, including Oracle, allow DBAs to create separate constraints that are set on given tables, which allows DBAs to turn constraints off and on during database operations, e.g.:

 

ALTER TABLE tableName

Add Constraint constraintName

someConstraint

 

Can you imagine when, if ever, you might want to separate a constraint from the table definition it modifies? If so, describe the circumstances; if not, explain why not.
