Rules and NULL values  Unbinding rules

Chapter 13: Defining Defaults and Rules for Data

After defining a rule

After you define a rule, the source text describing the rule is stored in the text column of the syscomments system table. Do not remove this information; doing so may cause problems for future versions of Adaptive Server. Instead, encrypt the text in syscomments by using sp_hidetext, described in the Reference Manual. For more information, see “Compiled objects”.
