<div><p>It is possible to run iSeries™ server commands by using stored

procedures. The two examples that are provided here apply to ODBC programs.</p>

<div class="section"><p>Simply call <span class="cmdname">Execute Command (QCMDEXC)</span> to run
|
||
|

the command. The process is relatively simple, but ensure that you include

all of the zeros in the length parameter. Use the <span class="apiname">Remote Command</span> API

as an alternative.</p>

writes data into the joblog for the job running the SQL (in this case, the

ability to work with multi-member files. You cannot create a multi-member

file through CREATE TABLE. However, the following example shows you how to

access with ODBC anything but the first member of a file that is created through

DDS:</p>
