Using Key Ranges with an NDB

If an NDB contains large amounts of data, or if you want to separate the data records from the key and control records, you can use the KEYRANGES AMS parameter. The information about the key structure of an NDB enables you to do separate the records.

Note: This information is for guidance only. The key structures can alter with future product releases. If you divide NDBs by key ranges, review this information whenever you install a new release of your product.
