php调用mysql存储过程_php技巧

前面转载了一篇《php调用mysql存储过程的文章》经过测试，发现文章中的方法似乎不可行！

调用带有select语句的存储过程就出现 PROCEDURE p can't return a result set in the given context的错误。google了半天，在mysql官网上找到一些说法，db_mysql的模块不支持存储过程调用，解决方法是用db_mysqli。测试了一下，果然可以了。

用法比较简单，没啥好说的，从网上copy一段代码吧：


/* Connect to a MySQL server */
$link = mysqli_connect(
'localhost', /* The host to connect to */
'root', /* The user to connect as */
'root', /* The password to use */
'db_name'); /* The default database to query */
if (!$link) {
printf("Can't connect to MySQL Server. Errorcode: %s\n", mysqli_connect_error());
exit;
}
/* Send a query to the server */
if ($result = mysqli_query($link, "call se_proc('crm')")) {
/* Fetch the results of the query */
while( $row = mysqli_fetch_array($result) ){
echo ($row[0]. "--------- SR. " . $row[1] . "
");
}
/* Destroy the result set and free the memory used for it */
mysqli_free_result($result);
}
/* Close the connection */
mysqli_close($link);
?>

郁闷的是费了半天劲搞出来的存储过程效率居然不如以前- -
