### 1.给attendance_cfg表中增加is_default int 1-默认，0-非默认

更新历史数据

UPDATE attendance_cfg set is_default=1

更新历史数据

UPDATE pro_mobile_attendance_data pmad
INNER JOIN (
SELECT ac.project_id, ac.id AS cfg_id
FROM attendance_cfg ac
WHERE ac.is_default = 1 AND ac.enabled = 1
) ac ON pmad.project_id = ac.project_id
SET pmad.cfg_id = ac.cfg_id
WHERE pmad.att_device = 'device' AND pmad.cfg_id = 0;

### 2.attendance_ubi_data表增加cfg_id保存配置ID

更新历史数据

UPDATE attendance_ubi_data a
SET cfg_id = (
SELECT id
FROM attendance_cfg
WHERE project_id = a.projectid
AND com_id = a.comId
AND is_default = 1
AND enabled = 1
LIMIT 1
)
WHERE a.cfg_id IS NULL;


### 3.性能优化


-- 主表复合索引
CREATE INDEX idx_pro_mobile_attendance_project_att ON pro_mobile_attendance_data(project_id, att_date DESC, id DESC);

-- 用户表索引
CREATE INDEX idx_pro_project_users_id ON pro_project_info_subdepts_users(user_id);

-- 字典表索引
CREATE INDEX idx_sys_dict_type_value ON sys_dict_data(dict_type, dict_value);

### 4.给attendance_cfg表中增加cfg_name varchar(100) 用于保存配置名称，前端是必填

更新历史数据

update attendance_cfg set cfg_name='默认配置'

### 5.attendance_ubi_device表增加cfg_id  int 配置编号

更新历史数据

UPDATE attendance_ubi_device ud
SET cfg_id = (
SELECT id
FROM attendance_cfg
WHERE project_id = ud.project_id
AND com_id = ud.com_id
AND is_default = 1
AND enabled = 1
LIMIT 1
)
WHERE ud.cfg_id IS NULL;
