HomeDatabaseMysql Tutorialphp调用mysql5存储过程方法

本文章介绍了关于在php中调用mysql5的存储过程,为什么只讲mysql5呢,原因很简单因为只有mysql5.0及以后的版本才支持存储过程哦,下面我们从入门及开始看。

1。调用存储过程的方法。

a。如果存储过程有 IN/INOUT参数,声明一个变量,输入参数给存储过程,该变量是一对,

一个变量(也可以不必,只是没有php变量时,没有办法进行动态输入),一个Mysql

变量。

b。如果存储过程有OUT变量,声明一个Mysql变量。

变量的声明比较特殊,必须让mysql服务器知道此变量的存在,其实也就是执行一条mysql语句。

入set @mysqlvar=$phpvar ;

c。使用mysql_query()/mysql_db_query()执行mysql 变量声明语句。

 代码如下 复制代码

mysql_query("set @mysqlvar【=$pbpvar】");

这样,在mysql服务器里面就有一个变量,@mysqlar。如果时IN参数,那么其值可以有phpar传入。

d。 如果时存储过程。

1。执行 call procedure()语句。

也就是mysql_query("call proceduer([var1]...)");

2. 如果有返回值,执行 @ar,返回执行结果。

 代码如下 复制代码

mysql_query("select @var)"

接下来的操作就和php执行一般的mysql语句一样了。可以通过mydql_fetch_row()等函数获得结果。

如果时函数。 直接执行 select function() 就可以了。

 

 代码如下 复制代码
$host="localhost";
$user="root";
$password="11212";
$db="samp_db";
$dblink=mysql_connect($host,$user,$password)
or die("can't connect to mysql");
mysql_select_db($db,$dblink)
or die("can't select samp_db");
$res=mysql_query("set @a=$password",$dblink);
$res=mysql_query("call aa(@a)",$dblink);
$res=mysql_query("select @a",$dblink);
$row=mysql_fetch_row($res);
echo $row[0];

从网上找的一个实例

 代码如下 复制代码
/* 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: %sn", 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);
?>


这个查找后会返回数据数据集哦

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
