Making Python work with Snowflake For Fun and Pleasure
As we did last week in our post on Creating a new function in Snowflake, I want to talk about some of the scripts and languages I use to make my life easier in Snowflake. As the site LearnPython says: “Today, Python is one of the most popular programming languages because of its beginner-friendly syntax, efficiency, and…… Continue reading Making Python work with Snowflake For Fun and Pleasure
Creating a new function in Snowflake
Sometimes, you’ll need to create functions that do a particular thing. They’re not always pretty. Some of them look like they should have been thrown out with the bathwater. Unlike SQL Server, user-defined functions in Snowflake can be done in several different languages. They can be done in Java, JavaScript, Python, Scala, or plain-old SQL.…… Continue reading Creating a new function in Snowflake

Check Out these URLs with Snowflake Functions
When we’re working with fields that have websites in them, one of the things that we should be doing with them is to double-check that they’re well-formed and usable. Thankfully, Snowflake has a function just for that. With the PARSE_URL function, we can check out if everything is properly formed – meaning that we have…… Continue reading Check Out these URLs with Snowflake Functions
In CASE You Want to Use Logic in Snowflake

Figuring out the Number of Months Between Days
Figuring out the number of years or months between 2 dates shouldn’t be hard. For some reason though, for a lot of database systems it is. Take, for example, SQL Server. If I want to know the number of months between 1/1/2023 and 7/4/2023, it’s not too hard. A simple DATEDIFF function and we’re golden.…… Continue reading Figuring out the Number of Months Between Days
Getting the Minimum or Maximum of One Column
By the title of this post, you’re thinking “Ho hum. Sherpa will tell us about the stupid MIN and MAX functions in Snowflake and how great they are.” Well, they are great. Let’s not kid ourselves about that one. SELECT department_id, MIN(employee_id) AS FirstEmp FROM public.employees GROUP BY department_id ORDER BY department_id; This simply tells…… Continue reading Getting the Minimum or Maximum of One Column
Next Friday Will Be Here Before You Know it
Sometimes, you’ll be asked to show the next Friday after a given date in a report. Sometimes, it’s the next Monday. Let’s work thru how to do it in both SQL Server and Snowflake for comparison… One of the two ways we’ll go over in SQL Server is using the DateFirst operator. This operator actually…… Continue reading Next Friday Will Be Here Before You Know it
