[AccessD] Comparing Values of Fields

Hi Karen

Apart from the obvious (comparing each pair of fields in a query) you
can calculate for each record an MD5 or SHA-256 hash value of a string
build by concatenating the formatted values:

The retrieve those records where the hash values don't match.
You could also calculate the CRC value.
