如何在mysql中新创建的VIEW中更改属性？

Question

所以我创建了一个观点，并希望用新的名称视图的新列，例如：

CREATE VIEW monthly_view AS 
(SELECT co.object_id, co.object_alias, cm.method_alias, dr.data_value, 
      cd.data_uom, dr.date_timestamp, dr.delay_value, dr.delay_pct 
FROM data_realtime AS dr 
JOIN chroniker_object AS co ON co.object_id=dr.object_id 
JOIN chroniker_data AS cd ON cd.data_id=dr.data_id 
JOIN chroniker_method AS cm ON cm.method_id=co.method_id) 

我要的是每当显示“monthly_view”中，“co.object_id”即可显示为“对象”。

感谢

Answer 1

您可以使用一个别名：

CREATE VIEW monthly_view AS 
SELECT co.object_id AS Object, 
     co.object_alias AS ..., 
     cm.method_alias AS ..., 
     ... 
FROM 
     ... 

Answer 2

select co.object_id AS object, .... 

Answer 3

您是否尝试过在SELECT语句中指定别名？

CREATE VIEW monthly_view AS 
(SELECT co.object_id AS Object, 
     co.object_alias AS ObjectAlias, 
     .... 
FROM data_realtime AS dr 
JOIN chroniker_object AS co ON co.object_id=dr.object_id 
JOIN chroniker_data AS cd ON cd.data_id=dr.data_id 
JOIN chroniker_method AS cm ON cm.method_id=co.method_id)
