一次SQL没有指定字段类型导致的错误

1：表结构如下

CREATE TABLE `t_hft_dict` (

  `iAutoID` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '自增ID',
  `sType` varchar(120) NOT NULL COMMENT '字段的类别',
  `sKey` varchar(320) NOT NULL COMMENT '字典的key',
  `sValue` text COMMENT '字典的值',
  `iOrder` tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '排序',
  `sDesc` varchar(250) DEFAULT NULL COMMENT '描述',
  `iStatus` tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '状态',
  `iCreateTime` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '创建时间',
  `iUpdateTime` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '更新时间',
  `iDeleteTime` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '删除时间',
  PRIMARY KEY (`iAutoID`),
  UNIQUE KEY `idu_goup_key` (`sType`,`sKey`) USING BTREE

) ENGINE=InnoDB AUTO_INCREMENT=483 DEFAULT CHARSET=utf8；

第一次提交SQL 插入两条数据

INSERT INTO t_hft_dict (`sType`, `sValue`, `sKey`, `iOrder`, `sDesc`, `iStatus`, `iCreateTime`, `iUpdateTime`) VALUES ('hft_user_quarters_mapping', '{"3_1":{"name":"销售+新房","role":[{"id":"37","name":"驻场"}],"product":[{"id":"10","name":"驻场订单"},{"id":"55","name":"新房KA拓展"},{"id":"56","name":"新房项目拓展"},{"id":"57","name":"新房项目维护"}],"business":{"id":"1","name":"新房业务"}}}','3_1',0,'岗位与业务线和角色映射关系(sKey:岗位_业务线)',1,'1510284556','1510284556');

INSERT INTO t_hft_dict (`sType`, `sValue`, `sKey`, `iOrder`, `sDesc`, `iStatus`, `iCreateTime`, `iUpdateTime`) VALUES ('hft_user_quarters_mapping', '{"3":{"name":"销售","role":[{"id":"3","name":"销售"}],"product":[{"id":"","name":""}],"business":{"id":"","name":""}}}','3',0,'岗位与业务线和角色映射关系(sKey:岗位_业务线)',1,'1510284556','1510284556');

第二次提交SQL：update t_hft_dict set sValue='{"3":{"name":"销售","role":[{"id":"28","name":"销售"}],"product":[{"id":"","name":""}],"business":{"id":"","name":""}}}' where sType='hft_user_quarters_mapping' and sKey=3;

思考：更新的数据时几条：

由于sKey是字符串，而值3没有用引号引上，导致查询时 3和3_1两条数据都被更新了
