Vertica 从连接重复键列创建视图

Question

当我尝试通过连接在 Vertica 中创建视图时，

CREATE VIEW c AS 
    SELECT * FROM a JOIN b ON a.key = b.key;

我收到错误消息，因为键列重复：

ROLLBACK 5450:  View definition can not contain duplicate column names "key"

在非 Vertica SQL 中，我知道当两个键列名称相同时我可以使用 USING 关键字，~~但 Vertica 没有 USING~~ [编辑：wij pointed out that Vertica SQL does have USING]. I could also list out columns explicitly instead of selecting *, but one of the tables has hundreds of columns and I want them all (except for the duplicate key). There also doesn't seem to be an easy way 到 select 除了一列。

当列名相同但没有 USING 时，有没有一种方法可以 select 连接中只有一个键列？

Answer 1

写入列的列表（因为两个表都有字段键），例如：

CREATE VIEW c AS 
SELECT a.*, b.field1, b.field2 FROM a JOIN b ON a.key = b.key;

Vertica 从连接重复键列创建视图

Vertica create view from join duplicate key columns
