Unbinding a rule disconnects it from a particular column or user-defined datatype. An unbound rule’s definition remains in the database and is available for future use.
There are two ways to unbind a rule:
Use sp_unbindrule to remove the binding between a rule and a column or user-defined datatype.
Use sp_bindrule to bind a new rule to that column or datatype. The old one is automatically unbound.
Here is how to disassociate debtrule (or any other currently bound rule) from friends_etc.debt:
sp_unbindrule "friends_etc.debt"
The rule is still in the database, but it has no connection to friends_etc.debt.
To unbind a rule from the user-defined datatype p#,
sp_unbindrule "p#"
The complete syntax of sp_unbindrule is:
sp_unbindrule objname [, futureonly]
If the objname parameter you use is not of the form “table.column,” Adaptive Server assumes it is a user-defined datatype. When you unbind a rule from a user-defined datatype, the rule is unbound from all columns of that type unless:
You use the optional futureonly parameter, which prevents existing columns of that datatype from losing their binding with the rule, or
The rule on a column of that user-defined datatype has been changed so that its current value is different from the rule being unbound.
