下面是一个示例代码,演示了如何将timestamp转化为字符串: importdatetimedeftimestamp_to_string(timestamp):dt_object=datetime.datetime.fromtimestamp(timestamp)returndt_object.strftime("%Y-%m-%d %H:%M:%S")timestamp=1634200184string_

这里不详细展开了,从to_timestamp内置函数的注释就可以看出,目前只支持前面两种日期格式,因此暂时没办法用Spark内置函数来支持更广义的字符串转timestamp功能。 Spark UDF设计 为了实现更完善的字符串转timestamp功能,我们只能通过拓展UDF的方法来实现,实现代码如下。 def main(argv: Array[String]): Unit = { val ...

在表Timestamp_Sample中创建了数据类型为TIMESTAMP的两列timestp1和timestp2,并且为timestp2指定了时间的精度为 3。向两列同时使用TO_TIMESTAMP(string, format)插入日期值2020-01-01 11:00:00。从结果中可以看到timestp1由于没有指定scale的值,所以结果时间精度默认为 6 位,timestp2在指定后精度为 3 位。
-Format allows us to pass a formatting parameter to Get-Date. -AsObject returns the output as a series of PSCustomObjects instead of Strings. -All outputs blank lines, which are normally excluded. function Add-TimeStamp { param ( [string]$Format = $null, [switch]$AsObject, [switch]$Al...
