<h1 class="topictitle1">Retaining cursor positions across ILE program calls</h1>
|
||
|
|
<div><p>For ILE program calls, the close SQL cursor (CLOSQLCSR) parameter
|
||
|
|
allows you to specify the scope of the following: </p>
|
||
|
|
<div class="section"><ul><li>The cursors</li>
|
||
|
|
<li>The prepared statements</li>
|
||
|
|
<li>The locks</li>
|
||
|
|
</ul>
|
||
|
|
<p>When used properly, the CLOSQLCSR parameter can reduce the number
|
||
|
|
of SQL OPEN, PREPARE, and LOCK statements needed. It can also simplify applications
|
||
|
|
by allowing you to retain cursor positions across program calls. </p>
|
||
|
|
<dl><dt class="dlterm"><u><strong>*ENDACTGRP</strong></u></dt>
|
||
|
|
<dd>This is the default for the ILE precompilers. With this option, SQL cursors
|
||
|
|
and prepared statements remain open until the activation group that the program
|
||
|
|
is running under ends. They cannot be used by other programs, only by a different
|
||
|
|
call to the same program. Locks remain until the activation group ends.</dd>
|
||
|
|
<dt class="dlterm">*ENDMOD</dt>
|
||
|
|
<dd>With this option, a cursor remains open and accessible only while the
|
||
|
|
module that opened it is active. When the module ends, the SQL cursor can
|
||
|
|
no longer be used. Prepared statements will also be lost when the module ends.
|
||
|
|
Locks, however, remain until the last SQL program in the call stack completes.</dd>
