-- 第5步：修复方案（根据诊断结果选择执行）
|
||
-- ========================================
|
||
|
||
-- 方案A：如果 create_user_id 为空，手动关联到当前用户
|
||
-- ⚠️ 执行前请先确认你的用户ID！
|
||
-- 例如：假设你的用户ID是 1（admin通常是1）
|
||
|
||
-- 查看需要修复的题库
|
||
SELECT
|
||
id AS 题库ID,

||

||

|
||
FROM study_question_bank

||
WHERE create_user_id IS NULL;
|
||
|
||
-- 修复：将 create_user_id 设置为当前用户ID
|
||
-- UPDATE study_question_bank
|
||
-- SET create_user_id = 1 -- ⚠️ 替换为你的用户ID
|
||
-- WHERE create_user_id IS NULL;
|
||
|
||
|
||
-- 方案B：如果题库的 question_count 不准确，重新统计
|
||
UPDATE study_question_bank b
|
||
SET question_count = (

SELECT COUNT(*)

||
|
||
|
||
-- ========================================
|
||
-- 第6步：验证修复结果
|
||
-- ========================================
|
||
|
||
-- 6.1 验证：模拟后端查询（当前用户的题库）
|
||
-- ⚠️ 将 1 替换为你的实际用户ID
|
||
SELECT
|
||
id AS 题库ID,
|
||
bank_name AS 题库名称,

||

||

|
||
create_time AS 创建时间
|
||
FROM study_question_bank
|
||
WHERE create_user_id = 1 -- ⚠️ 替换为你的用户ID
|
||
ORDER BY create_time DESC;
|
||
|
||
-- 6.2 如果上面的查询有结果，说明修复成功
|
||
-- 刷新考试管理页面，应该能看到题库了

-- ========================================
|
||
-- 使用说明
|
||
-- ========================================
|
||
--
|
||
-- 1. 先执行第1-4步的诊断SQL，查看问题原因
|
||
-- 2. 根据诊断结果，选择执行第5步的修复SQL
|
||
-- 3. 执行第6步验证修复结果
|
||
-- 4. 刷新前端页面（考试管理 → 创建考试 → 选择题库）
|

|
||
-- 常见问题：
|
||
-- Q1: 题库列表为空
|
||
-- A1: create_user_id 为空，执行方案A修复
|
||
--
|
||
-- Q2: 题库有题目但显示数量为0
|
||
-- A2: question_count 不准确，执行方案B修复
|
||
--
|
||
-- Q3: 题库和题目都存在但考试管理中看不到
|
||
-- A3: create_user_id 与当前登录用户ID不匹配，执行方案A修复
