Id或[TableName] Id作为主键/实体标识符

问题描述

首选使用Id作为主键的列名称或[TableName] Id作为命名约定？

Is it preferred to use "Id" as the column name for a primary key or "[TableName]Id" as a naming convention?

- 对 -

$ b $在我看到的实现中，似乎分解了大约50％/ 50％。每种方法有哪些优点和缺点？

It seems to be split about 50% / 50% in the implementations that I've seen. What are the advantages and disadvantages in each approach?

后续行动：

使用一个约定是有意义的我的数据库，另一个在我的实体代码中？还是应该保持一致？

Does it make sense to use one convention in my database, and another on my entities in code? Or should I keep them consistent? How would does this work best in most ORMs?

推荐答案

TableNameID for clarity

1. 提高JOIN的可读性


2. 说清楚，多个FKID列（PK匹配FK）


3. ID是保留关键字
