Unbinds a rule from a column or from a user-defined datatype.


sp_unbindrule objname [, futureonly [, “accessrule” | “all”]]



is the name of the table and column or of the user-defined datatype from which the rule is to be unbound. If the parameter is not of the form “table.column”, then objname is assumed to be a user-defined datatype. Unbinding a rule from a user-defined datatype also unbinds it from columns of the same type. Columns that are already bound to a different rule are unaffected.


prevents columns of the specified user-defined datatype from losing their rules. It is ignored when unbinding a rule from a column.


indicates that you are unbinding the access rule bound to objname.


specifies that you are unbinding all rules bound to objname.


Example 1

Unbinds the rule from the startdate column of the employees table:

sp_unbindrule "employees.startdate"

Example 2

Unbinds the rule from the user-defined datatype named def_ssn and all columns of that type:

sp_unbindrule def_ssn

Example 3

The user-defined datatype ssn no longer has a rule, but existing ssn columns are unaffected:

sp_unbindrule ssn, futureonly

Example 4

You can use the all parameter to unbind both accesss rules and domain rules. For example, to unbind all the access rules and domain rules on the publishers table:

sp_unbindrule publishers, null, "all"

To unbind the access rule from a user-defined datatype for subsequent uses of this datatype, issue:

sp_unbindrule def_ssn, futureonly, "accessrule"

To unbind both access rules and domain rules for subsequent uses of this datatype, issue:

sp_unbindrule def_ssn, futureonly, "all"

Example 5

This access rule is bound to the publishers table:

sp_bindrule empl_access, "publishers.pub_id"

To unbind this rule, issue the following:

sp_unbindrule "empl_access", NULL, "accessrule"



Only the object owner can execute sp_unbindrule.
