int 只是个基本数据类型 而integer 就类似一个类，它不仅包含了int 数据，还包含了对这种数据所做的各种处理。所以一般对int数据有其他操作时，就要用到integer了。我的理解是这样的
I even made the values in the varchar columns to be '1', '2', '3', etc. so that they were storing the same values, but in different data types. My results showed that on a 1 million row INNER JOIN, the integer was about twice as fast. This was on a P4 2.0GHz desktop with ...

contributing to the extra disk space being used. I would suspect that since the GUID values are random there would be quite a bit more fragmentation with this datatype versus the integer which is ever increasing. Let’s take a look at the fragmentation of each index using the T-SQL below...
请注意,这只是一个基本的映射表,具体的映射可能因实际需求和数据库设计而有所不同。例如,有时你可能希望将 TINYINT 映射为 Integer 而不是 Byte,或者你可能希望将 DECIMAL 映射为 Double 而不是 BigDecimal,这完全取决于你的具体需求。 同时,MyBatis 也支持自定义的类型处理器(Type Handler),如果你需要处理特殊...
