Question

Spark document Built-in Functions has function such as day, date, month.

However, they are not available in PySpark. Why is this?

    day,
    date,
    month
)

      3     date,
      4     month
      5 )

ImportError: cannot import name 'day' from 'pyspark.sql.functions' (/opt/spark/spark-3.1.2/python/lib/pyspark.zip/pyspark/sql/functions.py)

Answer 1

Replace day with dayofmonth, date with to_date, month stays similiar.

from pyspark.sql.functions import dayofmonth, to_date, month, col

dateDF = spark.createDataFrame([("06-03-2009"),("07-24-2009")],"string")
dateDF.select(
    col("value"),
    to_date(col("value"),"MM-dd-yyyy")).show()

+----------+--------------------------+
|     value|to_date(value, MM-dd-yyyy)|
+----------+--------------------------+
|06-03-2009|                2009-06-03|
|07-24-2009|                2009-07-24|
