用 PHP 调用 MySQL 存储过程

MySQL 5.0 以上支持存储过程。
    PHP 5.0 以上的 mysqli 系列函数可以支持操作 MySQL 的存储过程。
    以下是一些简单的存储过程和用 PHP 调用的示例。

    一、返回单个数据:

1:  <?php 2:    header(”Content-Type:text/html;charset=utf-8″); 3:    4:    $host = “localhost”; 5:    $user = “root”; 6:    $password = “mypassword”; 7:    $db = “test_store_proc”; 8:    $dblink = mysqli_connect($host, $user, $password, $db) or die(”can’t connect to mysql”); 9:   10:    $dblink->query(’SET NAMES UTF8′);11:    if ($result = $dblink->query(”CALL sp_test0(@num, @x, 123)”))12:    {13:      $rs = $dblink->query(”select @num”);14:      $row = $rs->fetch_array();15:      echo $row[’@num’], ‘<br>’;16:   17:      $rs = $dblink->query(”select @x”);18:      $row = $rs->fetch_array();19:      echo $row[’@x’];20:   21:      mysqli_free_result($rs);22:    }23:    else24:      echo ‘error…’;25:    mysqli_close($dblink);26:   27:  /*28:  – Procedure “sp_test0″ DDL29:  CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_test0`(OUT num INT, OUT x VARCHAR(16), IN n INT)30:  BEGIN31:    DECLARE nouse int;32:    DECLARE tmp int;33:   34:    SELECT nId INTO nouse FROM open_news WHERE nID=39;35:    SELECT count(*) INTO tmp FROM open_news;36:    SET num = tmp;37:   38:    SET x = ‘XXX’;39:  END;40:  */41:  ?>42:

 

二、返回结果集:

:  <?php 2:    header(”Content-Type:text/html;charset=utf-8″); 3:    4:    $host = “localhost”; 5:    $user = “root”; 6:    $password = “mypassword”; 7:    $db = “test_store_proc”; 8:    $dblink = mysqli_connect($host, $user, $password, $db) or die(”can’t connect to mysql”); 9:   10:    $dblink->query(’SET NAMES UTF8′);11:    if ($result = $dblink->query(”call sp_test1()”))12:    {13:      while( $row = $result->fetch_array())14:      {15:        echo ($row[’nId’]. “–” . $row[’sTopic2′] . “<br>”);16:      }17:      mysqli_free_result($result);18:    }19:    else20:      echo ‘error…’;21:    mysqli_close($dblink);22:   23:  /*24:  – Procedure “sp_test1″ DDL25:  CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_test1`()26:  BEGIN27:     SELECT * FROM open_news WHERE nId<40;28:  END;29:  */30:  ?>

 

 三、返回多个结果集：

:  <?php 2:    header(”Content-Type:text/html;charset=utf-8″); 3:    4:    $host = “localhost”; 5:    $user = “root”; 6:    $password = “mypassword”; 7:    $db = “test_store_proc”; 8:    9:    $dblink = new mysqli($host, $user, $password, $db);10:    if (mysqli_connect_errno())11:    {12:      print(’Can not connect to MySQL server’);13:      exit;14:    }15:    else16:      print(’?????? MySQL ????????<br>’);17:   18:    $dblink->query(’SET NAMES UTF8′);19:    $rows = array();20:    if($dblink->real_query(”CALL sp_test2()”))21:    {22:      do23:      {24:        if($result = $dblink->store_result())25:        {26:          while ($row = $result->fetch_assoc())27:          {28:            array_push($rows, $row);29:          }30:          $result->close();31:        }32:      }33:      while($dblink->next_result());34:    }35:    else36:      echo ‘error…’;37:   38:    $dblink->close();39:   40:    print_r($rows);41:  /*42:  – Procedure “sp_test2″ DDL43:  CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_test2`()44:  BEGIN45:    SELECT nId,sTopic2 FROM open_news LIMIT 0, 5;46:    SELECT count(nId) AS counter FROM open_news;47:  END;48:  */49:  ?>
