-- 修复admin科研访问美国记录状态 - 执行脚本
-- 执行时间：2025-01-08
-- 目标：将admin的科研访问美国记录状态从"进行中"更新为"已完成"

-- 第一步：查询当前状态（执行前确认）
SELECT 
    '执行前状态检查' as check_type,
    record_id, application_id, applicant_name, purpose, destination,
    completion_status,
    CASE 
        WHEN completion_status = '0' THEN '进行中'
        WHEN completion_status = '1' THEN '已完成'
        WHEN completion_status = '2' THEN '提前结束'
        ELSE '未知状态'
    END as current_status_display,
    create_time, update_time
FROM rs_overseas_record 
WHERE applicant_name = 'admin' 
  AND purpose = '科研访问' 
  AND destination LIKE '%美国%'
  AND deleted = '0';

-- 第二步：执行更新操作
UPDATE rs_overseas_record 
SET completion_status = '1',           -- 设置为已完成
    update_time = NOW(),               -- 更新修改时间
    update_by = 1                      -- 设置修改人为管理员
WHERE applicant_name = 'admin' 
  AND purpose = '科研访问' 
  AND destination LIKE '%美国%'
  AND deleted = '0'
  AND completion_status = '0';         -- 只更新当前为"进行中"的记录

-- 第三步：查询更新后状态（执行后确认）
SELECT 
    '执行后状态检查' as check_type,
    record_id, application_id, applicant_name, purpose, destination,
    completion_status,
    CASE 
        WHEN completion_status = '0' THEN '进行中'
        WHEN completion_status = '1' THEN '已完成'
        WHEN completion_status = '2' THEN '提前结束'
        ELSE '未知状态'
    END as updated_status_display,
    create_time, update_time
FROM rs_overseas_record 
WHERE applicant_name = 'admin' 
  AND purpose = '科研访问' 
  AND destination LIKE '%美国%'
  AND deleted = '0';

-- 第四步：验证联合查询结果（模拟前端查询）
SELECT 
    '联合查询验证' as query_type,
    record_id,
    application_id,
    applicant_name,
    purpose,
    destination,
    completion_status,
    CASE 
        WHEN completion_status = '0' THEN '进行中'
        WHEN completion_status = '1' THEN '已完成'
        WHEN completion_status = '2' THEN '提前结束'
        ELSE '未知状态'
    END as final_status_display,
    CASE 
        WHEN record_id IS NOT NULL THEN '来自记录表'
        ELSE '来自申请表'
    END as data_source
