Because declarative referential integrity constraints are currently not supported between tables on different nodes of a distributed database, the mutating table restrictions do not apply to triggers that access remote nodes. Now, if you want to modify the emplist column, which is the nested table of employees, then you can define an INSTEAD OF trigger over the column to handle the operation. Do not use loop-back database links to circumvent the trigger restrictions. After you have completed the task that required the trigger to be disabled, re-enable the trigger, so that it fires when appropriate. Such applications might behave unpredictably. The object privileges to the schema objects referenced in the trigger body must be granted to the trigger's owner explicitly not through a role. Also, if global package variables are updated within a trigger, then it is best to initialize those variables in a BEFORE statement trigger. The mutating error still prevents the trigger from reading or modifying the table that the parent statement is modifying. For system triggers, compatibility must be 8. If included, then the expression in the WHEN clause is evaluated for each row that the trigger affects.
