Description

</title>
|
|
<para>
|
|
<command>CLOSE</command> frees the resources associated with an open cursor.
|
|
After the cursor is closed, no subsequent operations
|
|
are allowed on it. A cursor should be closed when it is
|
|
no longer needed.
|
|
</para>
|
|
<para>
|
|
An implicit close is executed for every open cursor when a
|
|
transaction is terminated by <command>COMMIT</command>
|
|
or <command>ROLLBACK</command>.
