ORA-32485: element in cycle column list of CYCLE clause must appear in the column alias list of the WITH clause element
Error Explanation:
Oracle ORA-32485 occurs when there is an element in the cycle column list of the CYCLE clause which does not appear in the column alias list of the WITH clause.
Common Cases:
This error will occur when the user attempts to use a column in the cycle clause that is not defined in the preceding SELECT statement. This could be caused by an incorrectly specified column name or an undefined alias.
Resolution:
To resolve this error, the user will need to check their SELECT statement and ensure that all column names used in the CYCLE clause are defined in the SELECT statement. Additionally, they should check that the correct syntax is used when specifying the columns in the WITH clause. Once all of the correct syntax is used, then the statement should be able to be executed properly and the error will be resolved.
