Which method is used to join two tables based on their position within the tables?

The method used to join two tables based on their position within the tables is referred to as "Join by Record Position." This approach allows you to combine two datasets by aligning each record in one table with the corresponding record in another table based solely on their order. It is particularly useful when the datasets being combined are guaranteed to have a one-to-one correspondence in their rows.

In scenarios where the record order is meaningful and consistent, this method offers a straightforward way to merge data without the need for matching fields or unique keys. It assumes that the position of each record is what links the data, making it efficient for certain types of analyses or when working with data that lacks a unique identifier or other common key fields.

Other methods like joining by field type, index, or unique identifier rely on attributes or properties of the data rather than the physical layout or order of the records, which is not applicable when focusing on position-based joining.
