Oracle DB Error ORA-01731 circular view definition encountered

The following is the cause of this error:

Through a series of CREATE and DROP VIEW statements, a view was defined that refers to itself. For example, VIEW1 might include a column from VIEW2 that is defined as a column in VIEW1. View definitions may be seen by querying the data dictionary.

Action you can take to resolve this issue: Check the view definitions, remove any circular references, and retry the statements.
