mysql字段名和关键字冲突的问题

SELECT * FROM yun_roleright WHERE right LIKE '%{13}%';

SELECT * FROM yun_roleright WHERE `right` LIKE '%{13}%';

SELECT count(0) FROM sys_log  WHERE system = 'system'

ALTER table sys_log change system system1 varchar(255) CHARSET utf8 COLLATE utf8_general_ci NULL COMMENT '系统'

语法：
alter table <表名> change <字段名> <字段新名称> <字段的类型>。

SELECT count(0) FROM sys_log s  WHERE s.system = 'system'

SELECT count(0) FROM sys_log  WHERE `system` = 'system'

        if (StrUtil.isNotEmpty(conditionDTO.getSystem())) {
            wrapper.eq(SysLogEntity::getSystem, conditionDTO.getSystem());
        }
        if (conditionDTO.getStart() != null) {

//注：PageHelper是内部的一个工具类，对数据进行分页处理
