存储过程

CREATE  PROCEDURE  getUid (IN phone CHAR(11), OUT uid INT )
    READS SQL DATA
BEGIN
    select u.id  from mami_auth.tb_user u where u.cellphone like CONCAT('%',phone);
END;

# drop PROCEDURE getUid;

call getUid('6722',@uid);

函数

CREATE  FUNCTION  fn_get_uid (phone CHAR(11) )
    RETURNS INT
BEGIN
    RETURN  (select u.id  from mami_auth.tb_user u where u.cellphone like CONCAT('%',phone) );
END;

# drop FUNCTION fn_get_uid;

select fn_get_uid('6722') as uid;
