Hinweise

To get Rule object properties, users can be a member of the public fixed server role.

To set Rule object properties, users must have CREATE RULE permission on the parent database or be a member of the db_owner fixed database role.

To create a rule, users must have CREATE RULE permission on the parent database or be a member of the db_owner fixed database role.

To drop a rule, users must have ALTER permission on the schema to which the rule belongs.

To bind or unbind a rule to a table, users must have ALTER permission on the table.

To bind or unbind a rule to a data type, users must have ALTER permission on the schema to which the data type belongs.
