What is the method for keeping the hash value consistent even when the arrangement of columns varies during hash calculation?

edit

The method for keeping the hash value consistent even when the arrangement of columns varies during hash calculation is to use a deterministic hashing algorithm that generates the same hash value regardless of the order of the input. One such algorithm is the "sorted hash" method, where the values of each column are sorted alphabetically or numerically before the hash calculation is performed. This ensures that the order of columns does not affect the resulting hash value. Another method is to use a consistent hashing algorithm such as SHA-256 or MD5, which generates unique and consistent hash values for a given input regardless of input order.
