The <span class="function"><strong>cubrid_num_rows()</strong></span> function is used to get the
number of rows from the query result. You can use it only when the query
executed is a select statement. When you want to know such value for
INSERT, UPDATE, or DELETE query, you have to use the
<span class="function"><a href="function.cubrid-affected-rows.html" class="function">cubrid_affected_rows()</a></span> function.

Note: The <span class="function"><strong>cubrid_num_rows()</strong></span> function can only be used
