执行结果：
技术性解释：
一、主要函数
formatDateTime()
解析:函数根据给定的格式字符串来格式化时间。请注意：格式字符串必须是常量表达式，例如：单个结果列不能有多种格式字符串
语法:formatDateTime(Time, Format [, Timezone])
返回值:根据指定格式返回的日期和时间
小示列：
selectformatDateTime(toDate('2020-01-04'), '%D') as date
, formatDateTime(toDate('2020-01-04'), '%F') as date_1
, formatDateTime(toDate('2021-05-13'), '%Y-%m-%d') as date_2
, formatDateTime(toDate('2021-05-13'), '%Y-%m') as year_month;selectformatDateTime(toDateTime('2021-01-13 21:12:13'),'%Y-%m-%d %R:%S') format_1-- %R24小时HH:MM时间，相当于%H:%M
, formatDateTime(toDateTime('2021-01-13 21:12:13'),'%Y-%m-%d %H:%M:%S') format_2-- %H 24小时格式（00-23)
, formatDateTime(toDateTime('2021-01-13 21:12:13'),'%Y-%m-%d %I:%M:%S') format_3-- %I 小时12h格式（01-12)
, formatDateTime(toDateTime('2021-01-13 21:12:13'),'%Y-%m-%d %p %I:%M:%S') format_4; -- %p 指定AM或PM支持的格式修饰符如下：
