sql - CREATE VIEW 使用多个表

Question

您好，尝试在 oracle 中创建 View 。但是，我的代码中出现错误，我无法解决。目前我正在尝试创建一个显示经理，他们的名字和姓氏也分配给他们的诊所诊所的PK和诊所地址的FK所有地址都存储在该表中(是的，我知道这不是标准的，但这是我选择的方式)所以我还想显示他们工作的诊所的详细地址

当然这包括两个我不确定如何实现的 WHERE 语句第一个是 STAFFJOBNAME "MANAGER"

第二个是 ADDRESSNO 在两个表上匹配的位置

CREATE VIEW MANAGER AS
    SELECT STAFF.staffno,STAFF.staffFirstName,STAFF.staffLastName,CLINIC.clinicNo, CLINIC.addressNo
    FROM STAFF,CLINIC
    WHERE addressNo = 
    (
        SELECT addressNo, addressStreet, addressCity, addressCounty, addressPostcode, addressTelephone,
        FROM ADDRESS,
        INNER JOIN CLINIC,
        ON ADDRESS.addressNo = CLINIC.addressNo
    ) AND STAFF.staffJobName = 'MANAGER';

我也有这个版本。所以我不确定哪个更接近正确的。

CREATE VIEW MANAGER
(
    AS
    SELECT STAFF.staffno,STAFF.staffFirstName,STAFF.staffLastName,CLINIC.clinicNo, CLINIC.addressNo, ADDRESS.addressNo, ADDRESS.addressStreet, ADDRESS.addressCity, ADDRESS.addressCounty, ADDRESS.addressPostcode, ADDRESS.addressTelephone,
    FROM ADDRESS, STAFF,
    INNER JOIN CLINIC,
    ON ADDRESS.addressNo = CLINIC.addressNo
);

Answer 1

CREATE VIEW MANAGERANDCLINIC    AS
    SELECT STAFF.staffno,STAFF.staffFirstName,STAFF.staffLastName,CLINIC.clinicNo, ADDRESS.addressStreet, ADDRESS.addressCity, ADDRESS.addressCounty, ADDRESS.addressPostcode, ADDRESS.addressTelephone
    FROM STAFF,CLINIC, ADDRESS
    WHERE (CLINIC.CLINICMANAGERNO = STAFF.STAFFNO) AND
    (CLINIC.ADDRESSNO = ADDRESS.ADDRESSNO)
    ORDER BY CLINIC.CLINICNO;
