【问题描述】：
我使用 CQL 创建了一个以 SET 作为列的表。
CREATE TABLE z_test.activity_follow (
activity_type_id text,
error_message text,
error_type text,
file text,
line_no text,
project_api_key text,
project_name text,
project_party_id text,
release_stage_id text,
stage_name text,
project_type_name text,
activity_type_name text,
account_id text,
created_at text,
secure_url text,
error_count text,
user_id set<text>,
PRIMARY KEY (activity_type_id,error_message,error_type,file,line_no,project_api_key,project_name,project_party_id,release_stage_id,stage_name,project_type_name,activity_type_name,account_id,created_at,secure_url)
);
z_test 是我的密钥空间。
然后我使用以下查询将一个值插入到表中，
UPDATE z_test.activity_follow SET user_id = user_id + {'46'} , error_count = '4'
WHERE activity_type_id = '1'
AND error_message = '1'
AND error_type = '1'
AND FILE = '1'
AND line_no = '1'
AND project_api_key = '1'
AND project_name = '1'
AND project_party_id = '1'
AND release_stage_id = '1'
AND stage_name = '1'
AND project_type_name = '1'
AND activity_type_name = '1'
AND account_id = '1'
AND secure_url = '1'
AND created_at = '1'
UPDATE z_test.activity_follow SET user_id = user_id + {'464'} , error_count = '4'
WHERE activity_type_id = '1'
AND error_message = '1'
AND error_type = '1'
AND FILE = '1'
AND line_no = '1'
AND project_api_key = '1'
AND project_name = '1'
AND project_party_id = '1'
AND release_stage_id = '1'
AND stage_name = '1'
AND project_type_name = '1'
AND activity_type_name = '1'
AND account_id = '1'
AND secure_url = '1'
AND created_at = '1'
值已成功插入。我使用了以下选择语句，
SELECT * FROM z_test.users WHERE emails CONTAINS 'test@mail.com';
我得到了以下结果，
activity_type_id | error_message | error_type | file | line_no | project_api_key | project_name | project_party_id | release_stage_id | stage_name | project_type_name | activity_type_name | account_id | created_at | secure_url | error_count | user_id

然后我从表格中删除了一封电子邮件，
UPDATE z_test.activity_follow SET user_id = user_id - {'46'} , error_count = '4'
WHERE activity_type_id = '1'
AND error_message = '1'
AND error_type = '1'
AND FILE = '1'
AND line_no = '1'
AND project_api_key = '1'
AND project_name = '1'
AND project_party_id = '1'
AND release_stage_id = '1'
AND stage_name = '1'
AND project_type_name = '1'
AND activity_type_name = '1'
AND account_id = '1'
AND secure_url = '1'
AND created_at = '1'
现在当我使用上面的查询时，
SELECT * FROM z_test.activity_follow WHERE user_id CONTAINS '46';
它仍然返回该行，
activity_type_id | error_message | error_type | file | line_no | project_api_key | project_name | project_party_id | release_stage_id | stage_name | project_type_name | activity_type_name | account_id | created_at | secure_url | error_count | user_id

为什么我会出现这种行为？在 CQL 中是预期的吗？如果我可以删除这个如何？我已将每个值都设为 1 进行测试，我也尝试了其他值。
【问题讨论】：
-
无法在本地重现该案例。您似乎也错过了描述中的创建索引步骤。你能设置“跟踪”吗？在 cqlsh 中，再次运行 select 并粘贴结果？
-
这对我也有用。我的猜测是在您上次更新期间发生了一些事情，导致索引没有更新。试试
nodetool rebuild_index <keyspacename> <tablename> (<optionalindexname>)看看是否有帮助。
