<para>
|

<function>pg_send_query</function> 向 <parameter>connection</parameter> 连接发送异步查询。和 <function>pg_query</function> 不同，它可以向 PostgreSQL 发送多个查询并用 <function>pg_get_result</function> 依次得到结果。当执行查询时脚本的执行不会被锁定。用 <function>pg_connection_busy</function> 来检查连接连接是否为忙（例如查询正在执行中）。调用 <function>pg_cancel_query</function> 则有可能取消查询。
|
||
</para>
|
||
<para>
|
||
尽管用户可以一次发送多个查询，但用户不能通过正忙的连接发送多个查询。如果向正忙的连接发送了查询，则会等待上一条查询结束并丢弃所有结果。
|
||
</para>
|
||
<para>
|
||
参见 <function>pg_query</function>，<function>pg_cancel_query</function>，<function>pg_get_result</function> 和 <function>pg_connection_busy</function>。
