使用mysql php查询创建视图将多个表合并到一个表中

如何命名四个表以构成一个表

Name table = (ID), (post_title)
sku table = (meta_id), (post_id), (meta_key), (meta_value)
Price table = (meta_id), (post_id), (meta_key), (meta_value)
stock table = (meta_id), (post_id), (meta_key), (meta_value)

此查询失败

CREATE VIEW fortress AS
SELECT name.ID, name.post_title, price.meta_value, sku.meta_value, stock.meta_value
FROM name
INNER JOIN price ON (name.ID = price.meta_id)
INNER JOIN key ON (name.ID = sku.meta_id)
INNER JOIN stock ON (name.ID = stock.meta_id)

发生了这个错误

1060-重复列名“meta_值”

您的解决方案是什么？

您需要为具有重复名称的列提供别名： 示例：

CREATE VIEW fortress AS
SELECT name.ID, name.post_title, price.meta_value AS price_meta_value, 
       key.meta_value AS key_meta_value, stock.meta_value AS AS stock_meta_value
FROM name`enter code here`
INNER JOIN price ON (name.ID = price.meta_id)
INNER JOIN key ON (name.ID = s.k.u.meta_id)
INNER JOIN stock ON (name.ID = stock.meta_id)
