To remove a rule from the database entirely, use the drop rule command. Unbind the rule from all columns and user datatypes before you drop it. If you try to drop a rule that is still bound, Adaptive Server displays an error message, and drop rule fails. However, you need not unbind and then drop a rule to bind a new one. Simply bind a new one in its place.
To remove phonerule after unbinding it:
drop rule phonerule
The complete syntax for drop rule is:
drop rule [owner.]rule_name [, [owner.]rule_name] ...
After you drop a rule, new data entered into the columns that previously were governed by it goes in without these constraints. Existing data is not affected in any way.
A rule can be dropped only by its owner.
