[我正在尝试使用SQL Developer中的联接从多个表中检索数据，但出现错误ORA-00933：SQL命令未正确结束

Question

select 
    e.first_name, e.last_name, 
    e.first_name || e.last_name "Name",
    d.department_name, d.manager_id,
    l.country_id, l.city
from 
    employees e
join 
    departments d on e.department_id = d.department_id
join 
    locations l on d.location_id = l.location_id
where 
    d.manager_id = &d.manager_id;

Answer 1

删除并在您的where语句中，我猜这是问题所在。

“名称”，d.department_name，d.manager_id，l.country_id，l.city来自雇员e在e.department_id = d.department_id上加入部门d.location_id = l.location_id 其中d .manager_id = d.manager_id;

Answer 2

尝试一下，检查是否对您有帮助；）

select 
e.first_name, e.last_name, 
concat(e.first_name, ' ', e.last_name) "Name",
d.department_name, d.manager_id,
l.country_id, l.city
from 
employees e
join 
departments d on e.department_id = d.department_id
join 
locations l on d.location_id = l.location_id
where 
d.manager_id = &d.manager_id;
