Javascript does not have a proper (static) enum type, but you can achieve something very close using the same code Typescript generates for its enums. To offer enums but still be valid JS, you want an object where each enum element (name) is a key, mapping to a unique value (typic...

注意数值类型括号后面的数字只是表示宽度而跟存储范围没有关系,比如INT(3)默认显示3位,空格补齐,超出时正常显示,python、java客户端等不具备这个功能。 e.使用短数据类型,比如取值范围为0-80时,使用TINYINT UNSIGNED。 f.不建议使用ENUM类型,使用TINYINT来代替。
The way the final keyword works in Java is that the variable's pointer to the value cannot change. Let's repeat that: it's the pointer that cannot change the location to which it's pointing. There's no guarantee that the object being referenced will stay the same, only that the variab...
