Updating multiple columns

Question

I have an UPDATE statement with some complex CASE statements in the inner SELECT query which makes it impossible to set values like column_name1 = value1, column_name2=value2 . So i am getting ORA-00927: missing equal sign error.
The UPDATE looks like
SQL> UPDATE EMPCLONE
  2  SET EMPNO,ENAME,JOB=(SELECT EMPNO,ENAME,JOB FROM EMP);
SET EMPNO,ENAME,JOB=(SELECT EMPNO,ENAME,JOB FROM EMP)
ERROR at line 2:
ORA-00927: missing equal signAny workarounds?
