🧪 The Problem: Getting the Min/Max of Two Integers in Postgres/SQL

So you're wondering how to get the maximum or minimum value of two integers in Postgres/SQL? Maybe you have a specific problem, like subtracting an integer from a column but ensuring the result is never less than zero. Well, fret not! I got you covered with easy solutions. Let's dive in! 🏊‍♂️

🚀 Scenario: Subtracting an Integer from a Column

Let's say you have a table called my_table with a column called my_column. You want to subtract a fixed value (let's say 10) from my_column for all rows. However, you want to make sure the result is never negative.

💡 The Solution: Using the MAX() Function

To achieve your desired result, you can use the MAX() function in combination with the subtraction operation. Here's an example of how you can update your table using this approach:

UPDATE my_table
SET my_column = MAX(my_column - 10, 0);

In this query, MAX(my_column - 10, 0) will calculate the difference between my_column and 10, and then return the maximum value between that difference and 0. This ensures that the updated value of my_column will never be less than 0.

🎉 Problem Solved!

With just a single line of SQL code, you can subtract an integer from a column and prevent negative results. How cool is that? 😎
