There are multiple ways how to get the raw SQL query for an Eloquent call – we are using Tinkerwell daily and so this is our natural way to debug queries. This is super useful if you debug server crashes or want to know how much memory your application server needs. The LIKE a query is used in a WHERE clause to search. You see all executed queries, the time that the query run, the memory consumption and even the peak for your memory. When you put the search form in your application, you need to use like query to get matched pattern.
If you write your query in Tinkerwell anyway, you can highlight the Eloquent query and press Cmd+Shift+R (or Ctrl+Shift+R if you are on Windows) and Tinkerwell profiles the query directly in the editor. That's why findOrFail () method in Laravel eloquent is useful for this kind of scenario. While you can get the raw SQL query with the methods above, there are situations where you debug the runtime or memory allocation of a query and want to know why it takes longer than expected.
