<< What is this new feature about? What are stats with indexes? >> Unless you have databases in the multi-GB range, there really is no advantage to removing the index statistics. They are there to support a lot of useful features in DBISAM like logical record numbers, accurate record counts with ranges, and accurate query I/O cost estimations, so removing them has some serious downsides. -- Tim Young Elevate Software www.elevatesoft.com |

I could not find any info on your website. |

<< Well, my question is that does it pay to upgrade to get stats?

As to whether you need that ability, it really depends upon if you are going to have DBISAM tables in the GB range or higher. As for paying, you're actually paying for a support plan, if your support plan has expired, so you're actually paying for *any* minor releases to DBISAM over the next year. -- Tim Young Elevate Software www.elevatesoft.com |
