Rules in Sql Server

Q. How to drop same rule applied on all the table in a single statement using sp_MSforeachtable (in Point 2 )?

1. // Rule apply on one table

create table table1
(id int , name varchar(10), city varchar(10))


create rule namerule
as
len(@name)<10


sp_bindrule namerule,'table1.name'

sp_unbindrule'table1.name'

drop rule namerule

2. // Same Rule apply on both the  table

create table table1
(id int , name varchar(10), city varchar(10))

create table table2
(id int , name varchar(10), city varchar(10),  primary key (id) )

create rule namerule
as
len(@name)<10

sp_bindrule namerule,'table1.name'
sp_bindrule namerule,'table2.name'

sp_unbindrule'table1.name';
sp_unbindrule 'table2.name'

Exec sp_MSforeachtable 'drop rule ?'   // Please correct this line
