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: else
24: echo 'error...';
25: mysqli_close($dblink);
26:
27: /*
28: -- Procedure "sp_test0" DDL
29: CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_test0`(OUT num INT, OUT x VARCHAR(16), IN n INT)
30: BEGIN
31: 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:
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_test1()"))
12: {
13: while( $row = $result->fetch_array())
14: {
15: echo ($row['nId']. "--" . $row['sTopic2'] . "<br>");
16: }
17: mysqli_free_result($result);
18: }
19: else
20: echo 'error...';
21: mysqli_close($dblink);
22:
23: /*
24: -- Procedure "sp_test1" DDL
25: CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_test1`()
26: BEGIN
27: SELECT * FROM open_news WHERE nId<40;
28: END;
29: */
30: ?>
31:
三、返回多个结果集：
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:
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: else
16: print('?????? MySQL ????????<br>');
17:
18: $dblink->query('SET NAMES UTF8');
19: $rows = array();
20: if($dblink->real_query("CALL sp_test2()"))
21: {
22: do
23: {
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: else
36: echo 'error...';
37:
38: $dblink->close();
39:
40: print_r($rows);
41: /*
42: -- Procedure "sp_test2" DDL
43: CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_test2`()
44: BEGIN
45: SELECT nId,sTopic2 FROM open_news LIMIT 0, 5;
46: SELECT count(nId) AS counter FROM open_news;
47: END;
48: */
49: ?>
