ORA-01775 looping chain of synonyms tips

Oracle Error Tips by Burleson Consulting

ORA-01775 looping chain of synonyms

Cause: Through a series of CREATE synonym statements, a synonym was defined that referred to itself. For example, the following definitions are circular:

CREATE SYNONYM s1 for s2 
CREATE SYNONYM s2 for s3 
CREATE SYNONYM s3 for s1

Action: Change one synonym definition so that it applies to a base table or view and retry the operation.

It should also be noted that a user on Oracle DBA Forums mentioned that ORA-01775 may be thrown because of a synonym that was defined and referred to itself:

For example, the following definitions are circular:
CREATE SYNONYM s1 for s2 CREATE SYNONYM s2 for s3 CREATE SYNONYM s3 for s1
Change one synonym definition so that it applies to a base table or view and retry the operation.
