mysql创建和访问存储过程-----示例

<?php
header('Content-Type:text/html;charset=UTF-8');
$conn = mysql_connect('localhost', 'root', 'root') or die ("数据连接错误!!!");
mysql_select_db('test', $conn);

//实例一：无参的存储过程
$sql = "create procedure myproce()
begin
INSERT INTO user (username) VALUES ('s');
end;
";
$res = mysql_query($sql);//创建一个myproce的存储过程
$sql = "call test.myproce();";
$res = mysql_query($sql);//调用myproce的存储过程，则数据库中将增加一条新记录。
var_dump($res);

//实例二：传入参数的存储过程
//$sql = "create procedure myproce2(in score int)
//begin
//if score >= 60 then
//select 'pass';
//else
//select 'no';
//end if;
//end;
//";
//mysql_query($sql);//创建一个myproce2的存储过程
//$sql = "call test.myproce2(90);";
//$reslut = mysql_query($sql);//调用myproce2的存储过程,看不到效果，可以在cmd下看到结果。
//$array = mysql_fetch_array($reslut);
//var_dump($array);

//实例三：传出参数的存储过程
//$sql = "create procedure myproce3(out score int)
//begin
//set score=100;
//end;
//";
//mysql_query($sql);//创建一个myproce3的存储过程
//$sql = "call test.myproce3(@score);";
//mysql_query($sql);//调用myproce3的存储过程
//$result = mysql_query('select @score;');
//$array = mysql_fetch_array($result);
//echo '<pre>';print_r($array);

//实例四：传出参数的inout存储过程
//$sql = "create procedure myproce4(inout usernameflag int)
//begin
//SELECT * FROM user WHERE username = usernameflag;
//end;
//";
//mysql_query($sql);//创建一个myproce4的存储过程
//$sql = "set @usernameflag = 666";
//mysql_query($sql);//设置性别参数为1
//$sql = "call test.myproce4(@sexflag);";
//$result = mysql_query($sql);
//$array = mysql_fetch_array($result);
//echo '<pre>';
//print_r($array);

//实例五：使用变量的存储过程
//$sql = "create procedure myproce5(in a int,in b int)
//begin
//declare s int default 0;
//set s=a+b;
//select s;       #(返回值)意思是返回s;
//end;
//";
//mysql_query($sql);//创建一个myproce5的存储过程
//$sql = "call test.myproce5(6,6);";
//$result = mysql_query($sql);
//$array = mysql_fetch_array($result);
//echo '<pre>';print_r($array);

//实例六：case语法
//$sql = "
//create procedure myproce6(in score int)
//begin
//case score
//when 60 then select '及格';
//when 80 then select '及良好';
//when 100 then select '优秀';
//else select '未知分数';
//end case;
//end;
//";
//mysql_query($sql);//创建一个myproce6的存储过程
//$sql = "call test.myproce6(20);";
//$result = mysql_query($sql);
//$array = mysql_fetch_array($result);
//echo '<pre>';print_r($array);

//实例七：循环语句
//$sql = "
//create procedure myproce7()
//begin
//declare i int default 0;
//declare j int default 0;
//while i<10 do
//set j=j+i;
//set i=i+1;
//end while;
//select j;
//end;
//";
//mysql_query($sql);//创建一个myproce7的存储过程
//$sql = "call test.myproce7();";
//$result = mysql_query($sql);
//$array = mysql_fetch_array($result);
//echo '<pre>';print_r($array);

//实例八：repeat语句
//$sql = "
//create procedure myproce8()
//begin
//declare i int default 0;
//declare j int default 0;
//repeat
//set j=j+i;
//set i=i+1;
//until j>=10
//end repeat;
//select j;
//end;
//";
//mysql_query($sql);//创建一个myproce8的存储过程
//$sql = "call test.myproce8();";
//$result = mysql_query($sql);
//$array = mysql_fetch_array($result);
//echo '<pre>';print_r($array);

//实例九：loop语句
//$sql = "
//create procedure myproce9()
//begin
//declare i int default 0;
//declare s int default 0;
//
//loop_label:loop
//set s=s+i;
//set i=i+1;
//if i>=5 then
//leave loop_label;
//end if;
//end loop;
//select s;
//end;
//";
//mysql_query($sql);//创建一个myproce9的存储过程
//$sql = "call test.myproce9();";
//$result = mysql_query($sql);
//$array = mysql_fetch_array($result);
//echo '<pre>';print_r($array);

//实例十：删除存储过程
//mysql_query("drop procedure if exists myproce");//删除test的存储过程

//实例十一：存储过程中的游标
//总结：
//1.存储过程可用于InnoDB或MyISAM类型的表
//2.show procedure status显示数据库中所有存储的存储过程基本信息，包括所属数据库，存储过程名称，创建时间等<br>
//3.SHOW CREATE PROCEDURE myproce显示某一个存储过程的详细信息<br>
//4.创建相同名字的存储过程不会成功，即不能覆盖一个已经存在的存储过程

//$sql = 'SHOW CREATE PROCEDURE myproce3';
//$result = mysql_query($sql);
//while( $array = mysql_fetch_array($result) ){
//  echo '<pre>';print_r($array);
//}
