Pyspark: TypeError: 'Column' object 不可调用 --- 使用 Window Function

Question

#尝试在PySpark中使用Window函数

from pyspark.sql import Row, functions as F from pyspark.sql.functions import col, row_number from pyspark.sql.window import Window from pyspark.sql import SparkSession

Join_transaciones3_df = Join_transaciones3_df.withColumn("row_num", F.row_number().OVER(Window.partitionBy("Clave").orderBy(col("transaction_date"))))

收到此错误 --> TypeError: 'Column' object is not callable

Answer 1

您不需要将transaction_date包装在col方法中 - 试试这个：

Join_transaciones3_df = Join_transaciones3_df.withColumn("row_num", F.row_number().over(Window.partitionBy("Clave").orderBy("transaction_date")))
