=== 查询所有表 ===
  * list series
=== 查看表内容 ===

  * select * from "table" where 1=1 group by time(10m)
=== 删除表行 ===

  * delete from "table"
=== 删除表 ===

  * drop series "table"
=== 创建Fanout continuos query (sql没有group by语句) ===

  * select * from "table_a" into table_b where table_a.value > 10
  * 当有新的列被插入table_a时，会自动判断值是否大于10,如果大于10则也同时插入table_b（如果table_b不存在会自动创建。table_a中旧的值不会被影响
  * table_a中旧的值不受影响
=== 创建Downsampling continuos query (sql有group by语句，且只能group by time() ) ===

  * 与Fanout continuos query不同，Downsampling continuos query对旧值和新插入的值都有影响
=== 查看continuos query ===

  * list continuous queries
=== 删除continuos query ===

  * drop continuous query <id> （这个动作不会删除continuous query创建的表）
  * drop series "table"
