\n您可以在集群详情页的“数据查询”标签页选定数据库后执行只读查询，查看结果、查询耗时和返回行数，无需进入 VPC 或使用命令行工具。

\n

执行查询

\n
    \n
  1. 在“数据查询”标签页选择目标数据库。
    2. \n
  2. 在查询窗口输入 SQL 语句。
    3. \n
  3. 执行后查看结果、耗时和返回行数。
    4. \n
\n

查询语言由所选数据库的数据模型决定。当前数据模型为 Influx，查询语言为 SQL。页面上不能切换查询语言，语言由所选数据库的模型确定。

\n

\n

查询窗口只执行查询语句。您输入建表、删除等变更语句时会被拦截，并被指引到对应的数据库或表管理入口，而不是收到一条语法错误。

\n

查询限制

\n

为避免控制台查询影响集群承载的线上业务，单次查询受以下上限约束：

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
约束取值
单次返回行数默认 1000，最大 10000
单次结果大小10 MiB
单次查询超时60 秒
\n

平台还会限制单集群同时进行的控制台查询数量，达到限制时提示您稍后重试；具体条数由服务容量决定，不对外承诺。

\n

结果因上述上限被截断时，页面会显式提示结果不完整，不会静默截断。您可以主动终止正在执行的查询。

\n

查看与导出结果

\n\n

主动终止查询

\n

执行中的查询可以主动终止。终止请求会尽力停止后台查询；终止成功不代表一定没有查询仍在执行，请以页面返回的查询状态为准。查询已经完成时，终止不影响已返回的结果。

\n

查询历史

\n

查询历史只在您的浏览器本地保留，不在服务端持久化。查询属于正常的用户使用行为，不进入集群操作记录。

\n
