update语句是PHP+MySQL中常用的操作,判断update语句是否执行成功是其中非常重要的一个环节。本文就以实例展示了php+MySQL判断update语句是否执行成功的方法。分享给大家供大家参考之用。具体方法如下:

代码一:

$rs=MySQL_query($sql);
if(mysql_affected_rows())
echo "sql执行成功";
else
echo "sql执行失败";

代码二:

<&#63;php
  /* 连接数据库 */
  mysql_pconnect("localhost", "mysql_user", "mysql_passWord") or die ("Could not connect" . mysql_error());
  mysql_select_db("mydb");
  /* Update 记录 */
  mysql_query("UPDATE mytable SET used=1 WHERE id < 10");
  printf ("Updated records: %d\n", mysql_affected_rows());
  mysql_query("COMMIT");
&#63;> 

想观察update的执行情况mysql_affected_rows()是必需的。

相信本文所述对大家的PHP+MySQL程序设计有一定的借鉴价值。
