John If what you are really after is to display any records where a given field is duplicated, then I would say that a self join is the best bet. If you just pull 500 consecutive records out into an array, and perform the comparrisoon in php, then what happens if record 500 has a duplicate to record 1001 - you will never compare the two? Also, unless you particularly want to look at all of the records, if you do a self join on the field that you suspect could have duplicates, then you need only display those records that are suspect.
