The similarity between a stored procedure in SQL and a python function:

Alright, let’s ditch the formal lecture and just talk like humans for a sec.

So, you know how in Python you write a function to avoid copy-pasting the same code a million times? Like, you want to add two numbers or fetch some orders, you just slap those lines into a function and boom—use it wherever. SQL’s got its own thing for this: stored procedures. Same idea, just lives inside the database. Not quite as glamorous, but hey, it gets the job done.

Think of them both as those little Tupperware containers for your code. You throw in your ingredients—maybe some loops, a sprinkle of conditionals, maybe an angry error-handler if you’re feeling spicy—and pack it up for later. Need to do that task again? Just call the thing by its name. Easy.

Let’s get real—nobody wants to rewrite the same logic over and over (unless they hate themselves). So once you define a stored procedure in SQL or a function in Python, you just… reuse it. Pass in some parameters, like which customer’s orders you want, and it spits out the answer. Here, look:

SQL:

CREATE PROCEDURE GetOrdersByCustomer(IN cust_id INT)
BEGIN
    SELECT * FROM orders WHERE customer_id = cust_id;
END;
Enter fullscreen mode Exit fullscreen mode

Python:

def get_orders_by_customer(cust_id):
    orders = [o for o in orders_list if o['customer_id'] == cust_id]
    return orders
Enter fullscreen mode Exit fullscreen mode

Same vibe, right? You throw in a customer ID, it fetches their orders. The code doesn’t care if you’re wearing a data analyst hat or a developer hoodie, it just does the thing.

And yeah, both let you play with control flow—if/else, loops, the whole nine yards. You can get fancy, or just keep it basic. Whatever floats your boat.

Now, let’s talk performance. Stored procedures run right inside the database, which means less chatter over the network. Python functions? They just save you from writing garbage code and make your scripts less of a dumpster fire. Not rocket science, but it matters.

Bottom line: both Python functions and SQL stored procedures are just ways to keep your code tidy, reusable, and not a total headache to maintain. The main difference? One’s chilling in your database, the other’s out in the wild with the rest of your program. That’s really it. If you’re not using either, well, enjoy your spaghetti code.
