Best practices for MySQL queries
It would be difficult to write the best queries for reference and reuse. It will always vary based on the nature of your application, architecture, design, table structure, and so on. However, precautions can be taken while writing MySQL queries for better performance, scalability, and integrity.
Let's go through a few of the best practices that we should keep in mind while designing or writing MySQL queries.
Data types
A database table would consist multiple columns having data types such as numeric or string. MySQL 8 provides various data types than just limiting to numeric or string.
- Small is good. As MySQL loads data in memory, a large data size would adversely impact performance. Smaller sets can accommodate more data in memory and reduce overheads of resource utilization.
- Fix your length. If you don't fix the data type length, it would have to go and fetch the required information each time it needs. So, wherever it's possible, you can limit data length...
