Я хотел бы включить dname, deptno, loc, добавить ename и обозначить столбец как Number_of_People, суммировать зарплату, обозначить столбец Total Salary, затем присоединиться к таблице dept, и я хочу сделать это только для отдела 30
Вот ошибка, которую я получаю
SQL> select dname,deptno, loc, count(ename) as Number_of_People, sum(sal) as Total_Salary from emp join dept on emp.deptno = dept.deptno group by dname,loc where deptno =30;
select dname,deptno, loc, count(ename) as Number_of_People, sum(sal) as Total_Salary from emp join dept on emp.deptno = dept.deptno group by dname,loc where deptno =30
