如何完全停止TDengine数据库的连续查询？

Question

我按照官网的例子在TDengine数据库中创建了一个连续查询如下：

taos> create table meters (ts timestamp, current float, voltage int, phase float) tags (location binary(64), groupId int);
Query OK, 0 of 0 row(s) in database (0.002309s)

taos> create table D1001 using meters tags ("Beijing.Chaoyang", 2);
Query OK, 0 of 0 row(s) in database (0.002737s)

taos> create table D1002 using meters tags ("Beijing.Haidian", 2);
Query OK, 0 of 0 row(s) in database (0.004740s)

taos> create table avg_vol as select avg(voltage) from meters interval(1m) sliding(30s);
Query OK, 0 of 0 row(s) in database (0.005207s)

taos> show streams;
       streamId       |           user           |           dest table           |        ip:port         |      created time       |        exec time        |       time(us)        |              sql               |   cycles    |
=======================================================================================================================================================================================================================================
 3:1                  | _root                    | avg_vol                        | 127.0.0.1:37643        | 2022-01-21 16:20:32.538 | NULL                    |                     0 | select avg(voltage) from me... |           0 |
Query OK, 1 row(s) in set (0.002328s)

taos> kill stream 3:1;
Query OK, 0 row(s) in set (0.000418s)

taos> show streams;
Query OK, 0 row(s) in set (0.001015s)

看起来不错，但是重启数据库的时候还是看到这个连续查询，怎么彻底杀掉？

Answer 1

尝试删除您创建的目的地 table

drop table avg_vol;
