  <title>Description</title>

  <para>
   <command>MOVE</command> repositions a cursor without retrieving any data.
   <command>MOVE</command> works exactly like the <command>FETCH</command>
   command, except it only positions the cursor and does not return rows.
  </para>

  <para>
   The parameters for the <command>MOVE</command> command are identical to 
   those of the <command>FETCH</command> command; refer to
   <xref linkend="sql-fetch" endterm="sql-fetch-title">
   for details on syntax and usage.
  </para>
 </refsect1>

 <refsect1>
  <title>Outputs</title>

  <para>
   On successful completion, a <command>MOVE</> command returns a command
   tag of the form
<screen>
MOVE <replaceable class="parameter">count</replaceable>
</screen>
   The <replaceable class="parameter">count</replaceable> is the number
   of rows that a <command>FETCH</command> command with the same parameters
   would have returned (possibly zero).
  </para>
