....
############### tdengine 时间序列数据库 ###############
tdengine:
restart: always
image: tdengine/tdengine:latest
container_name: tdengine
ports:
- "6030:6030"
- "6041:6041"

Referring to the official example, it is almost the same as the syntax of mysql, which is standard SQL syntax:
taos> CREATE DATABASE demo;
Create OK, 0 row(s) affected (0.221636s)
taos> USE demo;
Database changed.
taos> CREATE TABLE t (ts TIMESTAMP, speed INT);
Create OK, 0 row(s) affected (0.001332s)
taos> INSERT INTO t VALUES('2019-07-15 00:00:00', 10);
Insert OK, 1 row(s) affected (0.000975s)
taos> INSERT INTO t VALUES('2019-07-15 01:00:00', 20);
Insert OK, 1 row(s) affected (0.000979s)
taos> SELECT * FROM t;
ts | speed |
========================================
2019-07-15 00:00:00.000 | 10 |
2019-07-15 01:00:00.000 | 20 |
Query OK, 2 row(s) in set (0.001955s)
