<div><p>If you processed the rows of a result table for a serial cursor,
|
||
|
|
and you want to use the cursor again, issue a CLOSE statement to close the
|
||
|
|
cursor prior to re-opening it.</p>
|
||
|
|
<div class="section"><p>The statement looks like this:</p>
|
||
|
|
<pre>EXEC SQL
|
||
|
|
<strong>CLOSE</strong> cursor-name
|
||
|
|
END-EXEC.</pre>
|

|
|
</div>
|
||
|
|
<div class="section"><p>If you processed the rows of a result table and you do not want
|
||
|
|
to use the cursor again, you can let the system close the cursor. The system
|
||
|
|
automatically closes the cursor when:</p>
|
||
|
|
<ul><li>A COMMIT without HOLD statement is issued and the cursor is not declared
|
||
|
|
using the WITH HOLD clause.</li>
|
||
|
|
<li>A ROLLBACK without HOLD statement is issued.</li>
|
||
|
|
<li>The job ends.</li>
|
||
|
|
<li>The activation group ends and CLOSQLCSR(*ENDACTGRP) was specified on the
|
||
|
|
precompile.</li>
|
||
|
|
<li>The first SQL program in the call stack ends and neither CLOSQLCSR(*ENDJOB)
|
||
|
|
or CLOSQLCSR(*ENDACTGRP) was specified when the program was precompiled.</li>
|
||
|
|
<li>The connection to the application server is ended using the DISCONNECT
|
||
|
|
statement.</li>
|
||
|
|
<li>The connection to the application server was released and a successful
|
||
|
|
COMMIT occurred.</li>
|
||
|
|
<li>An *RUW CONNECT occurred. <p>Because an open cursor still holds locks
|
||
|
|
on referred-to-tables or views, you should explicitly close any open cursors
|
||
|
|
as soon as they are no longer needed.</p>
