Understanding How to Print to the Console Before Running a Function in R
Understanding the Problem: Printing to the Console before a Function is Run When working with command-line interfaces, it’s not uncommon to want to display information to the user before a certain function or action is taken. However, in many programming languages, including R, functions are executed immediately when called, and any output is typically displayed after the function has completed its execution.
In this article, we’ll explore how to overcome this challenge and print messages to the console before a function is run in R.

How to Get the Most Recent Status for Each Order Line Using SQL's ROW_NUMBER() Function
Based on your code, it seems like you’re trying to get the most recent status for each order line. To achieve this, you can use the ROW_NUMBER() function with a partitioning clause.
Here’s an example of how you could modify your query:
SELECT ORDER_LINE_ID, STATUS_ID, OL_ID, STATUS_TS FROM ( SELECT * , ROW_NUMBER() OVER ( PARTITION BY ORDER_LINE_ID ORDER BY STATUS_TS DESC ) AS rn FROM ( SELECT * FROM TEMP_SALES_ORDER_DATA UNION ALL SELECT * FROM TEMP_RET_ORDER_DATA ) COLR WHERE STATUS_QTY > 0 ) COLR WHERE rn = 1; This will return the most recent status for each order line, sorted by timestamp in descending order.
