How do you get the SQL statement with variables replaced in Rails?

Question

When working with Rails and SQL Server you can capture the SQL statement with variables replaced by taking advantage of the ActiveRecord object that represents your query. This can be particularly helpful for debugging or logging purposes. One approach is to use the `to_sql` method on your ActiveRecord relation object. This method returns the SQL representation of the query with actual values substituted for the placeholders (question marks). Here's an example: # Assuming you have a model named `User` and you want to find users by their id user_id = 10 users_query = User.where(id: user_id) sql_query = users_query.to_sql puts sql_query In the above example `to_sql` is called on `users_query` which represents the ActiveRecord relation for finding users with the specified id. The resulting `sql_query` will hold the SQL statement with the `user_id` variable value (10 in this case) substituted into the query. By inspecting or logging this `sql_query` you can see the final SQL statement that will be executed by SQL Server with all the variable values in place. This method can be very helpful in understanding and optimizing your SQL queries within a Rails application that interacts with SQL Server.
