-- ============================================
-- 3. 检查数据条件：查看可能影响查询结果的数据
-- ============================================

-- 3.1 检查今天的挂号记录总数
SELECT 
    COUNT(*) AS total_count,
    COUNT(CASE WHEN delete_flag = '0' THEN 1 END) AS not_deleted_count,
    COUNT(CASE WHEN delete_flag = '1' THEN 1 END) AS deleted_count

-- 3.2 检查不同租户的数据分布
SELECT 
    tenant_id,
    COUNT(*) AS count,
    COUNT(CASE WHEN delete_flag = '0' THEN 1 END) AS not_deleted_count
FROM adm_encounter
WHERE start_time::DATE = CURRENT_DATE
GROUP BY tenant_id
ORDER BY tenant_id;

-- 3.3 检查不同状态的数据分布
SELECT 
    status_enum,
    COUNT(*) AS count,
    COUNT(CASE WHEN delete_flag = '0' THEN 1 END) AS not_deleted_count
FROM adm_encounter
WHERE start_time::DATE = CURRENT_DATE
  AND delete_flag = '0'
GROUP BY status_enum
ORDER BY status_enum;

-- 3.4 检查是否有患者数据关联
SELECT 
    COUNT(DISTINCT enc.id) AS encounter_count,
    COUNT(DISTINCT pt.id) AS patient_count,
    COUNT(DISTINCT CASE WHEN pt.delete_flag = '0' THEN pt.id END) AS patient_not_deleted_count
FROM adm_encounter enc
LEFT JOIN adm_patient pt ON enc.patient_id = pt.id
WHERE enc.start_time::DATE = CURRENT_DATE
  AND enc.delete_flag = '0';

-- 3.5 检查医生参与信息
SELECT 
    COUNT(DISTINCT enc.id) AS encounter_count,
    COUNT(DISTINCT ep.encounter_id) AS has_doctor_count,
    COUNT(DISTINCT ep.practitioner_id) AS doctor_count
FROM adm_encounter enc
LEFT JOIN adm_encounter_participant ep

    AND ep.type_code = 'admitter' 
    AND ep.delete_flag = '0'
WHERE enc.start_time::DATE = CURRENT_DATE
  AND enc.delete_flag = '0';

-- ============================================
-- 4. 快速查询：直接查看患者姓名和挂号信息（最简单）
-- ============================================
SELECT 
    enc.id AS 就诊记录ID,
    pt.name AS 患者姓名,
    pt.id_card AS 身份证号,

WHERE enc.delete_flag = '0'
  AND pt.delete_flag = '0'
  AND enc.start_time::DATE = CURRENT_DATE
ORDER BY enc.start_time DESC;

-- ============================================
-- 4.1 使用 create_time 查询（和门诊挂号页面一致）
-- ============================================
SELECT 
    enc.id AS 就诊记录ID,
    pt.name AS 患者姓名,
    pt.id_card AS 身份证号,
    pt.phone AS 联系电话,
    enc.create_time AS 创建时间,

WHERE enc.delete_flag = '0'
  AND enc.class_enum = 1  -- 门诊
  AND enc.create_time::DATE = CURRENT_DATE
ORDER BY enc.create_time DESC;

-- ============================================
-- 5. 快速检查：查看最近7天的挂号记录数量（使用 start_time）
-- ============================================
SELECT 
    start_time::DATE AS register_date,
    COUNT(*) AS total_count,
    COUNT(CASE WHEN delete_flag = '0' THEN 1 END) AS not_deleted_count
FROM adm_encounter
WHERE start_time::DATE >= CURRENT_DATE - INTERVAL '7 days'
GROUP BY start_time::DATE
ORDER BY start_time::DATE DESC;

-- ============================================
-- 5.1 快速检查：查看最近7天的挂号记录数量（使用 create_time）
-- ============================================
SELECT 
    create_time::DATE AS register_date,
    COUNT(*) AS total_count,
    COUNT(CASE WHEN delete_flag = '0' THEN 1 END) AS not_deleted_count
FROM adm_encounter
WHERE create_time::DATE >= CURRENT_DATE - INTERVAL '7 days'
  AND class_enum = 1  -- 门诊
GROUP BY create_time::DATE
ORDER BY create_time::DATE DESC;

-- ============================================
-- 6. 对比 start_time 和 create_time 的差异
-- ============================================
SELECT 
    id AS 就诊记录ID,
    start_time AS 开始时间,
    create_time AS 创建时间,
    (start_time::DATE) AS 开始日期,
    (create_time::DATE) AS 创建日期,
    status_enum AS 状态,
    delete_flag AS 是否删除
FROM adm_encounter
WHERE (start_time::DATE = CURRENT_DATE OR create_time::DATE = CURRENT_DATE)
  AND delete_flag = '0'
ORDER BY create_time DESC
LIMIT 20;
