-- 1. 查询申请表中admin用户科研访问美国的记录
SELECT 
    '申请表数据' as data_type,
    application_id, applicant_name, purpose, destination, 
    status as application_status,
    CASE 
        WHEN status = '0' THEN '待审核'

    start_date, end_date, 
    create_time, update_time
FROM rs_overseas_application 
WHERE applicant_name = 'admin' 
  AND purpose = '科研访问' 
  AND destination LIKE '%美国%'
  AND deleted = '0'
ORDER BY create_time DESC;

-- 2. 查询记录表中admin用户科研访问美国的记录
SELECT

-- 3. 查询申请和记录的对应关系
SELECT
