What is the issue when using both "Order" and "Distinct" in a single query in Rails?

edit

When using both "Order" and "Distinct" in a single query in Rails, it can cause unexpected results as "Distinct" only ensures that each record returned is unique, but it does not specify which of the unique records to return. "Order," on the other hand, specifies the order in which the records should be returned. Therefore, it can end up returning unexpected results as the order may alter the uniqueness of the records returned. It is recommended to use only one of these statements to ensure that the desired results are returned.
