</methodsynopsis>
<para>
The <function>cubrid_move_cursor</function> function is used to move the
current cursor location of <parameter>req_identifier</parameter> by the
value set in the <parameter>offset</parameter> argument, to the direction
set in the <parameter>origin</parameter> argument. To set the
<parameter>origin</parameter> argument, you can use <constant>CUBRID_CURSOR_FIRST</constant>
for the first part of the result, <constant>CUBRID_CURSOR_CURRENT</constant> for the current
location of the result, or <constant>CUBRID_CURSOR_LAST</constant> for the last part of the
result. If <parameter>origin</parameter> argument is not explicitly
designated, then the function uses <constant>CUBRID_CURSOR_CURRENT</constant> as its default
value.
</para>
<para>
If the value of cursor movement range goes over the valid limit, then the
cursor moves to the next location after the valid range for the cursor.
For example, if you move 20 units in the result with the size of 10, then
the cursor will move to 11th place and return <constant>CUBRID_NO_MORE_DATA</constant>.
