Dependencies for Triggers Compiled triggers have dependencies. For example, in place of a single AFTER row trigger that updates the original table, resulting in a mutating table error, you might use two triggers--an AFTER row trigger that updates a temporary table, and an AFTER statement trigger that updates the original table with the values from the temporary table. You are reloading data. This can occur many times before the statement completes successfully. Because stored procedures are stored in a compiled form, the work-around for the previous example is as follows: For example, do not assign a value to a global package variable in a row trigger if the current value of the global variable is dependent on the row being processed by the row trigger. This is similar to the privilege model for stored procedures. Enabling and Disabling Triggers A trigger can be in one of two distinct modes: The new column values are referenced using the new qualifier before the column name, while the old column values are referenced using the old qualifier before the column name. With this privilege, the trigger can be created in any schema and can be associated with any user's table.
