yesterday's date

Question

hello,
This is how I get todays date in three parts, year and month and day separately.
Question:
How can I do the same but for yesterday's date? please note the current date could be first of jan and so it needs to show accurately the previous day to be

year=2022

month=12

day=31

thank you

Hi @arkiboys,

Thank you for posting query in Microsoft Q&A Platform.

You can use the datetime module and dateutil library to get the previous date, year and month in PySpark.

from datetime import datetime
from dateutil.relativedelta import relativedelta

# Get the previous date
previous_date = datetime.today() - relativedelta(days=1)
# Get the previous year
previous_year = datetime.today() - relativedelta(years=1)
# Get the previous month
previous_month = datetime.today() - relativedelta(months=1)

Hope this helps. Please let me know if any further queries.

Thank you for asking the question. Azure Databricks supports a vide variety of built-in functions. This include several functions for date manipulation. I recommend you to go through the date functions in Azure Databricks from the below URL.

Basically, you can use the DateAdd Function to add or subtract days from the date. To subtract, pass the argument as negative. More details can be found in the below URL.
