Four Sharp Edges I Found in My Own Code
This article highlights significant design flaws discovered in a web GIS application related to SQL integration and user-generated inputs. The author's experience with a layer named '1' led to the identification of SQL injection vulnerabilities due to inadequate handling of user inputs in SQL commands, emphasizing the importance of robustness in coding practices. It underscores the need for stringent validation methods and better project organization, as various issues in naming conventions caused functional and performance discrepancies, such as view mismatches and unnecessary database clutter. The article serves as a cautionary tale for developers, urging them to prioritize security and consistency in their coding standards.

Summary
TL;DR
- Improper handling of SQL identifiers resulting in vulnerabilities
- Layer naming flaws leading to potential SQL injection attacks
- Mismatch in view names causing stranded database objects
- Importance of column order in database migrations
- Use of user-generated names directly in SQL commands
Interesting facts
- A layer named '1' was created due to lack of validation, proving dangerous.
- Views were created without considering identifier case sensitivity leading to duplicate entries.
- The author suggests composing DDL using sql.Identifier instead of f-strings.
