SQL Question

I'm trying to count the differences of one column in two identical tables (except for the data) ... I've tried

 select count(barcode_number) from property_temp   where
    barcode_number not in (select barcode_number from property)

but it takes about 15 minutes for this to run ....

any suggestions ??

Please email, my newsfeed seems to be a week behind !!!

thanks !!
