软件构造笔记 3.1 Data Type and Type Checking 1.数据类型 变量:用特定数据类型定义,可存储满足类型约束的值。 基本数据类型(primitive type):如int、long、double 对象数据类型(object type):如String、BIgInteger 对象类型间会形成层次结构 根节点是Object,所有类都有父节点,除了Object,省略extends语句,那么默认该...

It determines data types at run time, rather than compile time. Some examples of Python types include integers, floats, strings, and boolean. Dynamically typed languages stand in contrast to statically typed languages, like C++, Java, and Fortran, that perform type checking at compile time. One...

Therefore, I suggest utilizing thedatedatatype, even if the day is irrelevant to your data access. Additionally, you have the option to generate a computed column using the date, which can present the information in a desired format.
