HXTT DBF
Selecting from a large DBF table using index
Denis

Hello,

I am wondering if there is any trick (or tips) for how to deal with the following scenario:

We have a CUSTOMER table that has 360000+ records. It is a DBF and has a CDX index file.

In NetBeans IDE, under Services tab, I've added the table and execute the following statement: SELECT [name],custno,contact FROM CUSTOMER WHERE CUSTNO > '92000'; It takes several minutes to display the results.

I am wondering if you know of a way(query?) that I can perhaps utilize the existing CDX index to perform that operation faster? Or is it already using it by default?

Run once "create index abc of abc.cdx on CUSTOMER (custno);";
Then check whether your query be quicken.
