php - PHP 中的 MySQL 存储过程及示例

Question

有人可以帮我在 MySQL 中创建存储过程并从 PHP 调用它们吗？

Answer 1

DELIMITER $$

DROP PROCEDURE IF EXISTS `sp_user_login` $$
CREATE DEFINER=`root`@`%` PROCEDURE `sp_user_login`(
  IN loc_username VARCHAR(255),
  IN loc_password VARCHAR(255)
)
BEGIN

  SELECT user_id,
         user_name,
         user_emailid,
         user_profileimage,
         last_update
    FROM tbl_user
   WHERE user_name = loc_username
     AND password = loc_password
     AND status = 1;

END $$

DELIMITER ;

并通过 mysql_connection 规范和调用

$loginCheck="call sp_user_login('".$username."','".$password."');";

它将返回过程的结果。

Answer 2

您可以在 MySQL 中非常轻松地创建过程 -- 语法：-

`//add a delimiter; 
Create Procedure <procedure_name>(parameters "IN(for using inside the procedure)" and "OUT(for returning)")
Begin
   // doing some thing.
end;
//end delimiter;`

Call Procedure - `CALL <procedure_name>(parameter1, parameter2, ....)`

Example -

`DELIMITER //  
CREATE PROCEDURE EmployeeName(IN EId INT)  
BEGIN  
    SELECT EmpName FROM Employee WHERE EmpId = EID;  
END//`

打电话-假设我想知道员工ID“10”的姓名，所以-

CALL EmployeeName(10);
