I'm using TQuery to access data from 4 paradox dbs, and accessing one or two has good performance, but accessing 3 or more takes about 10 seconds to get the data. Is this common? Just to make sure, I did a similiar query on Interbase and it was thousands times faster! -Don Back to top Jarmo Guest Posted: Thu Jul 15, 2004 9:07 pm    Post subject: Re: Why is Paradox so slow!

This is the reason Interbase solves SQL queries more efficiently than Paradox. You can try change the position of some where clause conditions, sometimes it improves the query performance. Try to put the most restrictive condition first and keep the join clauses at the end of the where clause. Be sure that you have all the indexes you need, it can help Paradox to improve its performance. Remember that the more indexes you have the faster select statements will be, although insert and update statements will slow down. HTH Jayme.
