用PHP调用数据库的存贮过程!
作者:fox4000
昨天,看到一个战友问是否可以用php调用存贮过程,感觉应该是可以的,所以,马上进行了实验,非常的成功!非常出乎我的意料之外!因此,写出来,给大家参考!
大家知道,存储过程是在服务器端的一个脚本程序,执行起来速度很快,但它也有一个缺点,就是依赖与一个固定数据库,移植性不好!
我的上回文章,提到了用com组件是可以访问ado以及相关的组件,无论是自己建的还是系统带的,都可以扩展系统的功能,但现在php不支持dcom/com+,但相信它的下一个版本应该是支持的。
不说这么多了,我们马上试一下吧。
下面是我的一个简单的存贮过程
CREATE PROCEDURE [sp_mystoreprocedure] AS
select companyname, contactname, city from customers
其实,还可以写比较复杂的,可惜我对此研究不深,只好取简单了!
下面是我的php文件
define ("OLEDB_CONNECTION_STRING",
"Provider=SQLOLEDB; Data Source=zzb; Initial Catalog=Northwind; User ID=sa; Password=");
$dbc = new COM("ADODB.Connection");
$dbc->Open(OLEDB_CONNECTION_STRING);
$command = "sp_mystoreprocedure";
$rs = $dbc->Execute($command); // Recordset
$i = 0;
echo '
Directive | Local Value | Master Value |
---|---|---|
'; print $fld0->value; print ' | '; print $fld1->value; print ' |
'; print $fld2->value; print ' |
$rs->Close();
?>
注意的是,你的服务器必须打开!另外,就是不能写错存贮过程的名称。否则会出项致命的错误,而且,你根本就不知道错误在那里,这就是php文件对错误处理的不好之处,但相信它以后是会改进的。
我学php需然有很长时间了,但发现要真正用好它,不那么容易,但它确实也超出了我的想象,有些东西真的很奇妙,真是,不用不知道,一用真奇妙!
