# Structs
* brief 自增自减字段操作
* param [in] field_name 字段名称
* param [in] incData 加减数值,和表中定义的字段类型保持一致
* param [in] operation 操作类型,cmd.TcaplusApiOpPlus 加操作 cmd.TcaplusApiOpMinus 减操作
* param [IN] lower_limit 操作结果值下限,如果比这个值小,返回 TcapErrCode::SVR_ERR_FAIL_OUT_OF_USER_DEF_RANGE
支持double类型,int64(math.Float64bits(3.1415))
* param [IN] upper_limit 操作结果值上限,如果比这个值大,返回 TcapErrCode::SVR_ERR_FAIL_OUT_OF_USER_DEF_RANGE
支持double类型,int64(math.Float64bits(3.1415))
* note lower_limit == upper_limit 时,存储端不对操作结果进行范围检测

@param [IN] ttl 生存时间(过期时间),时间单位为毫秒,如果是相对时间,比如该参数值为10,则表示记录写入10ms之后过期,该参数值为0,则表示记录永不过期
如果是绝对时间,比如该参数值为1599105600000, 则表示记录到"20200903 12:00:00"之后过期,该参数值为0,则表示记录永不过期
@param [IN] IsAbsolute 时间类型是否为绝对时间,true表示绝对时间,false表示相对时间,默认是false,即相对时间
