The Problem: Multi-Digit Queries Failing
Imagine you are developing an application that interfaces with a MySQL database, and you find that your code works perfectly for single-digit queries but fails with two-digit numbers. In practical terms, when you attempt to execute a query with the ID of 10, you encounter the following error:
[[See Video to Reveal this Text or Code Snippet]]
What Causes This Error?
When passing a single value as a tuple, especially a fundamental value like an integer, it is essential to include a comma after the value. Specifically, (pinkode) treats pinkode as just a variable due to the absence of a comma and not as a single-element tuple. As a result, when using two-digit IDs (e.g., 10), this misinterpretation leads to the error you see.
The Solution: Correct Tuple Formatting
The solution to this problem is quite simple. You need to ensure that the variable passed to the cursor's execute method is formatted correctly as a single-element tuple. You can achieve this by adding a comma after the variable name. Here's the corrected line of code:

Breakdown of the Solution:
Use of Comma: By placing a comma after pinkode, you create a single-element tuple. This tells Python that it is indeed a tuple and not just the integer value.
No Need for Changes Elsewhere: All other parts of your code remain unchanged, ensuring that the logic for querying and handling data stays intact.
Conclusion
By following these simple practices, you will enhance your coding experience and avoid unnecessary frustration when coding database applications in Python and MySQL. If you're actively developing software that interfaces with MySQL, remember to check your tuple formatting—it might save you a significant amount of time debugging!
