Should You Use Backticks in MySQL Field Names?

Backticks in MySQL Field Names: Pros and Cons

Despite their occasional use in MySQL, the practice of enclosing field names in backticks has sparked debate among developers. While alguns condemn their use, others find them advantageous. Let's delve into the potential benefits and drawbacks.

Permitting Alternative Characters

Backticks allow the use of characters that are otherwise forbidden in field names, such as spaces and commas. This can be useful for creating more readable and descriptive field names, especially if they contain multiple words or punctuation.

For instance:

SELECT `id`, `my name`, `another field` , `field,with,comma` 

However, this flexibility can also lead to poorly named tables if backticks are used indiscriminately.

Compatibility with Query Generation Tools

Using backticks can enhance compatibility with query generation tools and automated query rewriting. These tools often rely on backticks to distinguish field names from other identifiers, ensuring proper parsing and rewriting.

Recommendation

Rather than mandating the use of backticks, it's preferable to establish naming standards that address potential issues with readability and validity. This approach addresses real-world problems more effectively than simply prohibiting or mandating backticks.
