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...
from pyspark.sql.types import * mySchema = StructType([ StructField("pcode",StringType()), StructField("lastName",StringType()), StructField("firstName",StringType()), StructField("age",IntegerType())]) myRDD = sc.textFile("people.txt").map(lambda line: line.split(",")).map(lam...
Please note that there are also convenience functions provided in pyspark.sql.functions, such as dayofmonth: pyspark.sql.functions.dayofmonth(col) Extract the day of the month of a given date as integer. Example: >>> df = sqlContext.createDataFrame([('2015-04-08',)], ['a']) ...
原因是pyspark to_timestamp只解析到秒,而TimestampType能够保存毫秒。以下解决方法可能有效:如果时间戳...
