Oracle Error SQL*Loader-00480: EXPRESSION may not be used with elements of a collection.

Oracle Error Message

SQL*Loader-00480: EXPRESSION may not be used with elements of a collection.

Reason for the Error

The EXPRESSION keyword is followed by a required SQL string expression and is used to load a column with the result of the SQL string expression instead of with a value from the input data file. However, this capability is not allowed with elements of a collection.

Solution

Remove the EXPRESSION keyword and associated SQL string from the collection element in the control file.
