Node.js中调用mysql存储过程示例

复制代码 代码如下:

/**
* 创建名为test的数据库
*/
DROP DATABASE IF EXISTS test;
CREATE DATABASE test;
USE test;
 
/**
* 创建user_info表
*/
DROP TABLE IF EXISTS `user_info`;

CREATE TABLE `user_info` (
  `userId` int(10) NOT NULL AUTO_INCREMENT,
  `userName` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`userId`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

/**
* 插入三条记录
*/
INSERT INTO user_info VALUES (NULL, '张一'), (NULL, '张二'), (NULL, '张三');

复制代码 代码如下:

DELIMITER $$
DROP PROCEDURE IF EXISTS `test`.`proc_simple`$$
CREATE PROCEDURE proc_simple(IN uid INT(10), OUT uName VARCHAR(2), OUT totalCount INT)
BEGIN

DECLARE str_name VARCHAR(20);

SET @str_name = '';
SET totalCount = 0;
        SELECT COUNT(1),userName INTO totalCount,@str_name FROM user_info WHERE userId = uid;       
        SET uName = @str_name;
        SELECT uName, totalCount;
       
    END$$
DELIMITER ;

复制代码 代码如下:
