Question

我正在尝试将来自不同架构的两个表连接到一个表中....这是我的查询。我一直收到一个错误，说它缺少右括号。任何人都可以帮我解决这个问题吗？我已经尝试了我能想到的所有可能的解决方案。我不相信它缺少一个，但它不会起作用。这是我的疑问：

create view  customers_g2 as 
select (    
(schema1.INTX.CUST_ID, 
schema1.INTX.CUST_NAME,
schema1.INTX.CUST_GENDER,
schema1.INTX.CUST_STATE,
schema1.INTX.COUNTRY_ID)
Join
select (KWEKU.KM_CUSTOMERS_EXT.CUST_ID, 
schema2.EXT.CUST_AGE, 
schema2.EXT.CUST_EDUCATION, 
schema2.EXT.MARRIED, 
schema2.EXT.NO_OF_CHILDREN, 
schema2.EXT.RACE, 
schema2.EXT.INCOME, 
schema2.EXT.CHECKING_BAL, 
schema2.EXT.SAVINGS_BAL, 
schema2.EXT.ASSETS, 
schema2.EXT.HOUSES)
from schema1.INTX,schema2.EXT 
where schema1.INTX.CUST_ID = schema2.EXT.CUST_ID);

Answer 1

尝试更改

create view  customers_g2 as (
                             ^ remove this parenthesis

到

create view  customers_g2 as

更新：更好地将整个事情改为

CREATE VIEW  customers_g2 
AS
SELECT i.CUST_ID, 
       i.CUST_NAME,
       i.CUST_GENDER,
       i.CUST_STATE,
       i.COUNTRY_ID,
       e.CUST_AGE, 
       e.CUST_EDUCATION, 
       e.MARRIED, 
       e.NO_OF_CHILDREN, 
       e.RACE, 
       e.INCOME, 
       e.CHECKING_BAL, 
       e.SAVINGS_BAL, 
       e.ASSETS, 
       e.HOUSES
  FROM schema1.INTX i JOIN
       schema2.EXT e ON i.CUST_ID = e.CUST_ID

唯一不合适的是

KWEKU.KM_CUSTOMERS_EXT.CUST_ID

目前还不清楚为什么需要第三种模式的

这个字段

Answer 2

你的sql太奇怪了.. 这是你想要的吗？

create view  customers_g2 as 
select 
schema1.INTX.CUST_ID, 
schema1.INTX.CUST_NAME,
schema1.INTX.CUST_GENDER,
schema1.INTX.CUST_STATE,
schema1.INTX.COUNTRY_ID,
schema2.EXT.CUST_ID, 
schema2.EXT.CUST_AGE, 
schema2.EXT.CUST_EDUCATION, 
schema2.EXT.MARRIED, 
schema2.EXT.NO_OF_CHILDREN, 
schema2.EXT.RACE, 
schema2.EXT.INCOME, 
schema2.EXT.CHECKING_BAL, 
schema2.EXT.SAVINGS_BAL, 
schema2.EXT.ASSETS, 
schema2.EXT.HOUSES
from schema1.INTX,schema2.EXT 
where schema1.INTX.CUST_ID = schema2.EXT.CUST_ID;

Answer 3

造成问题的无关括号是靠近第一个select：

的括号

create view  customers_g2 as (
select ( -- here
(schema1.INTX.CUST_ID,

此外，as之后的部分周围的parens并非绝对必要（请参阅here）。

您可能想要一种不同的联接：

create view customers_g2 as
  select ...long long list of all your columns...
  from schema1.INTX inner join schema2.INTX
  on schema1.INTX.CUST_ID = schema2.EXT.CUST_ID;

（警告：我所知道的关于加入的所有内容都来自here;如果我错了，请打电话给我。）

Oracle SQL加入两个表
