Error report -
ORA-02256: number of referencing columns must match referenced columns
02256. 00000 -  "number of referencing columns must match referenced columns"
*Cause:    The number of columns in the foreign-key referencing list is not
           equal to the number of columns in the referenced list.
*Action:   Make sure that the referencing columns match the referenced
           columns.
