create rule syntax  Rules bound to columns

Chapter 13: Defining Defaults and Rules for Data

Binding rules

After you have created a rule, use sp_bindrule to link the rule to a column or user-defined datatype.

Here is the complete syntax for sp_bindrule:

sp_bindrule rulename, objname [, futureonly] 

The rulename is the name of the rule created with create rule. The objname is the name of the table and column, or of the user-defined datatype to which the rule is to be bound. If the parameter is not of the form table.column, it is assumed to be a user datatype.

Use the optional futureonly parameter only when binding a rule to a user-defined datatype. All columns of a specified user-defined datatype become associated with the specified rule unless you specify futureonly, which prevents existing columns of that user datatype from inheriting the rule. If the rule associated with a given user-defined datatype has previously been changed, Adaptive Server maintains the changed rule for existing columns of that user-defined datatype.

The following restrictions apply to rules:
