Re: Best way to compare records

[Niels Liisberg <nli@xxxxxxxxxxxxxxxxx>]

What about using the "hash" function:

Do something like this and store / compare the hash value:

select *hash*(
       cusnum ||
       lstnam ||
       init   ||
       street ||
       city   ||
       state  ||
       zipcod ||
       cdtlmt ||
       chgcod ||
       baldue ||
       cdtdue )
