Jay,

thx for writing this down.

because SELECT PRY_INDEX
FROM T_PROPERTY
ORDER BY PRY_EXPORT_CITY

is super fast: 0.0074
I was hoping for more progress....

I have a few other ideas on how to optimize this query most of the ideas are based on keeping an extra table with the sorting order seperate etc.. so insert is more expensive... also will try out a few other database on how they behave in this kind of situtation, I tested openbase and that one is slower. Also gonna test postgressql just out of curiosity I don't have time now but in a week or so...


thx again, will defintely buy a copy of your book for all your efforst.
