ORA-32635: not a single cell reference predicate
Cause: A predicate that is not a single cell reference predicate was specified where a single cell reference predicate was expected. A single cell reference predicate is either a constant expression or a predicate of the form
Action: Make sure that the predicate is a proper single cell reference. In some cases, you might have to put explicit type conversion operators (or casts) on the constant expression
