与MAKE_DATE函数一样,MAKE_TIMESTAMP对Date字段执行相同的验证,并对时间字段进行额外的验证,小时的允许范围为0-23,分钟的允许范围为0-59,秒的允许范围为0-60。其中,秒的类型为小数,其精度为8,包含6位小数位。由于秒可以进一步细化,因此小数部分的精度最高为微秒。 例如在PySpark中: >>> df = spark.createDat...
在PySpark中,你可以使用to_timestamp()函数将字符串类型的日期转换为时间戳。下面是一个详细的步骤指南,包括代码示例,展示了如何进行这个转换: 导入必要的PySpark模块: python from pyspark.sql import SparkSession from pyspark.sql.functions import to_timestamp 准备一个包含日期字符串的DataFrame: python # 初始...
