ISQL or Application Programs

SQL Syntax


  ENABLE RULES

Description

  • ENABLE RULES returns the DBEnvironment session to its default behavior of firing all applicable rules.

  • The statement only affects the current SID (session id). Other users are not affected.

  • The ENABLE RULES statement is not cumulative; issuing additional ENABLE RULES statements will have no effect, and a warning will be issued to this effect.

  • Rules are not fired retroactively when the ENABLE RULES statement is issued after the DISABLE RULES statement has been issued. That is, if a DISABLE RULES statement is issued, rules that would otherwise be applicable will not fire. Then, when a subsequent ENABLE RULES is issued, applicable rules will fire again, but only for subsequent data manipulation statements, not for rows processed while rule firing was disabled.

  • COMMIT WORK and ROLLBACK WORK statements have no effect on whether rules are enabled or disabled.

Authorization

You must have DBA authority.
