<p>The Analyze Database File Keys (ANZDBFKEY) command produces, from the data generated by the Analyze Database File (ANZDBF) command, two reports showing the key structure of the database files.
|
||
|
|
</p>
|
||
|
|
<p>One report is written to the printer file QPPTANZK. The other report is written to the printer file QPPTANKM. QPPTANZK contains a listing of the access paths and (logical files only) selection criteria for each key field or selection rule. QPPTANKM contains a matrix of the key fields for all logical files based on the physical file.
