或许大家都设计过数据库,也为表定义过主键,今天我想阐述的是,应该如何正确的设计一个主键,在以往的一些资料中,都没有提及到主键设计的原则.我为此总结了一下: -you might have designed the database, as well as table-defined primary key, and today I would like to explain is that How should correct the design of a primary key, in the past some of the information. no mention of the primary key design principle. I summarize this for a moment :
