Accessing Raw SQL Queries from Database Query Builder
In Laravel's eloquent ORM, the database query builder allows you to easily execute database queries. However, there may be times when you need to retrieve the underlying SQL query string for inspection or debugging purposes.
Extracting Raw SQL Query
To retrieve the raw SQL query generated by a query builder instance, you can use the toSql() method. For example:
$rawSql = DB::table('users')->toSql();
This will return the raw SQL query string as a string. In the example provided, it would output:
select * from `users`
Advantages over Other Methods
Compared to other methods, such as event listeners, the toSql() method provides several advantages:
- Simple and Direct: It provides a straightforward way to obtain the raw SQL query without requiring complex event handling.
- Real-Time Inspection: You can retrieve the SQL query at any point during its construction, allowing you to inspect its final form.
- Works with Query Builder and Eloquent: The toSql() method works for both query builder and Eloquent models.
Important Notes
While the toSql() method allows you to retrieve the raw SQL query, it's important to note the following:
- This method does not execute the query. To run the query and retrieve the results, you must use methods like get(), first(), or execute().

Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1.

Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6.

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
