### `select_all`
`find_by_sql` has a close relative called `connection#select_all`. `select_all` will retrieve objects from the database using custom SQL just like `find_by_sql` but will not instantiate them. Instead, you will get an array of hashes where each hash indicates a record.
`find_by_sql` has a close relative called `connection#select_all`. `select_all` will retrieve objects from the database using custom SQL just like `find_by_sql` but will not instantiate them. This method will return an instance of `ActiveRecord::Result` class and calling `to_hash` on this object would return you an array of hashes where each hash indicates a record.
```ruby
Client.connection.select_all("SELECT first_name, created_at FROM clients WHERE id = '1'")
Client.connection.select_all("SELECT first_name, created_at FROM clients WHERE id = '1'").to_hash
