mybatis调用存储过程的实例代码

 create table p_user(    id int primary key auto_increment,    name varchar(10),   sex char(2) );  insert into p_user(name,sex) values('A',"男");  insert into p_user(name,sex) values('B',"女");  insert into p_user(name,sex) values('C',"男");  -- 创建存储过程(查询得到男性或女性的数量, 如果传入的是0就女性否则是男性) DELIMITER $ CREATE PROCEDURE mybatis.ges_user_count(IN sex_id INT, OUT user_count INT) BEGIN  IF sex_id=0 THEN SELECT COUNT(*) FROM mybatis.p_user WHERE p_user.sex='女' INTO user_count; ELSE SELECT COUNT(*) FROM mybatis.p_user WHERE p_user.sex='男' INTO user_count; END IF; END  $ -- 调用存储过程 DELIMITER ; SET @user_count = 0; CALL mybatis.ges_user_count(1, @user_count); SELECT @user_count;
