1、codename 作为翻译函数
CREATE DEFINER=`root`@`localhost` FUNCTION `codename`(`sys_code` varchar(20),`status` varchar(10)) RETURNS varchar(255) CHARSET utf8
BEGIN
#Routine body goes here...
RETURN (select mname from sys_param t where t.syscode =sys_code and t.mcode=status);
END
2、表
CREATE TABLE `sys_param` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`mcode` varchar(20) DEFAULT NULL COMMENT '翻译编码',
`mname` varchar(50) DEFAULT NULL COMMENT '翻译值',
`syscode` varchar(25) DEFAULT NULL COMMENT '参数编码',
PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT;
INSERT INTO `sys_param`(`id`, `mcode`, `mname`, `syscode`) VALUES (1, '0', '示教模式', 'device_panel_status');
INSERT INTO `sys_param`(`id`, `mcode`, `mname`, `syscode`) VALUES (2, '1', '自动模式', 'device_panel_status');
3、示例
select codename('device_panel_status', 1) as 状态;
