-- 将字符串状态统一为数字

-- UPDATE eb_follow_record SET follow_status = '1' WHERE follow_status = '关注';
|
||
-- UPDATE eb_follow_record SET follow_status = '0' WHERE follow_status = '取消关注' OR follow_status = '0';

|
||
-- 注意：执行前请确认用户ID不冲突

-- 第七部分：清理测试数据
|
||
-- ============================================

||
-- 14. 清理测试数据（如果需要）
|
||
-- DELETE FROM eb_live_room WHERE uid = 100;

|
||
|
||
-- ============================================
|
||
-- 使用说明
|
||
-- ============================================
|
||
-- 1. 先执行第一部分和第二部分，查看基础数据
|
||
-- 2. 在第三部分中，将 @USER_ID 替换为实际的用户ID，查看该用户应该看到的内容
|
||
-- 3. 执行第四部分，诊断可能的问题
|
||
-- 4. 根据诊断结果，参考第五部分的修复建议
|
||
-- 5. 如果需要测试，可以使用第六部分创建测试数据
|
||
-- 6. 测试完成后，使用第七部分清理测试数据
