<para>
<function>mysql_unbuffered_query</function> sends a SQL query to MySQL,
without fetching and buffering the result rows automatically, as
<function>mysql_query</function> does.
On the one hand, this saves a considerable amount of memory with SQL
queries that produce large result sets. On the other hand, you can start
working on the result set immediately after the first row has been
retrieved: you don't have to wait until the complete SQL query has been
performed.
</para>
<note>
<para>
The benefits of <function>mysql_unbuffered_query</function> come at a
cost: You cannot use <function>mysql_num_rows</function> on a result set
returned from <function>mysql_unbuffered_query</function>. You also have
to fetch all result rows from an unbuffered SQL query, before you can
send a new SQL query to MySQL.
