Oracle Message PLS-00401 - different column types between cursor SELECT statement and return value found at string

ERRORdifferent column types between cursor SELECT statement and return value found at string
CAUSEIn a cursor declaration, a return type (such as RETURN emp%ROWTYPE) was specified, but a returned column value and its corresponding select-list item have different datatypes.
ACTIONChange the cursor return type or the select list so that each returned column value and its corresponding select-list item have the same datatype.
