Answer 1

According to rails naming convention,

the table names should be the plural to the model names.

Example: User model table name should be users

As you said, you have a dump sql file,

first you should run db:schema:dump to dump the schema.

Next, if the table name of the dumped file is not according to the naming convention of rails, change the table_name using

self.table_name = "USER"

so, In your model,

class User < ApplicationRecord 
    self.table_name = "USER" 
end 

Now, User.all runs the command,

SELECT USER.* FROM USER
