The following syntax works in Oracle. Can you test if the same works in MYSQL too? It is called scalar subquery in Oracle.

You would just need to alias the two tables differently to distinguish between them if you are using the same table twice.

sql> select empno,
  2         (select dname from dept where deptno = emp.deptno) dname
  3    from emp 
  4    where empno = 7369;

     EMPNO DNAME
---------- --------------
      7369 RESEARCH

sql> select parent.empno,
  2         (select mgr from emp where empno = parent.empno) mgr
  3    from emp parent
  4    where empno = 7876;

     EMPNO        MGR
---------- ----------
      7876       7788
