PLS-00421: synonym definitions nested too deeply; possible
loop in synonyms



PLS-00421: synonym definitions nested too deeply; possible loop in synonyms..

Answer / guest

Cause: Directly or indirectly, a synonym was defined in
terms of itself, creating a circular definition. Or, a chain
of synonyms, too long for the PL/SQL compiler to handle, was
defined.

Action: Redefine the synonyms to eliminate the circular
definition. If necessary, shorten the chain of synonyms.
