Understanding the Backtick Issue in Laravel 10

If you're a developer working with Laravel, particularly version 10, you may have encountered a frustrating issue with raw SQL queries. Specifically, when using DB::raw() for SQL functions, you may notice that Laravel is incorrectly adding backticks around your SQL functions like concat(). This can result in errors, as the backticks suggest that the entire function is a column name rather than an executable function. In this guide, we'll explore why this happens and how to resolve it.

The Problem Explained

In previous versions of Laravel, specifically Laravel 9, it was common practice to write raw SQL lines like this:

However, upon upgrading to Laravel 10 and modifying your code to use the getValue method, you may have noticed that functions such as concat() are enclosed in backticks, leading to SQL errors. Specifically, you might see an error like:

This happens because the backticks cause the database to interpret the function as a column name instead of an executable function.

The Solution

Returning to Previous Practices

Interestingly, through some further investigation and experimentation, it has become clear that if you're operating inside a query builder, Laravel 10 can still handle DB::raw() similarly to how it worked in Laravel 9. This means that you don't have to change your original code structure:

Conclusion

If you're facing backtick errors in your Laravel 10 project when using raw SQL functions, remember that you're not required to modify your raw SQL statements. Rest assured that by sticking with your original form of the query, Laravel 10 will properly handle DB::raw() without surrounding your SQL functions with backticks.

Key Takeaways

Be aware that Laravel 10 has some quirks with DB::raw() enclosing function names in backticks.

You can retain your original query expressions without making changes when using DB::raw() inside query builders.

Always test your queries thoroughly after upgrading your Laravel version to catch such nuanced issues.

By understanding this and implementing the straightforward solution provided, you can avoid unnecessary headaches and keep your codebase clean and effective.
