I am trying to write a CQ with MODIFY statement that replaces all “Not Available” to NULL but I am getting an error “Left expression do not refer to an object”. Please refer to the screenshot for reference.

Modify function needs WAEvent as output stream.

SELECT * FROM OracleOutputStream; creates a typed/user-defined event

SELECT d FROM OracleOutputStream d; creates a WAEvent

Using * instead of an alias creates a user-defined event. Hence, there is an error in saving the component.
