Run the INSERT INTO statement to insert the data in the table to the associated OpenTSDB metric.

INSERT INTO TABLE_NAME SELECT * FROM SRC_TABLE;
INSERT INTO TABLE_NAME VALUES(XXX);

Parameter	Description
TABLE_NAME	Indicates the name of the associated OpenTSDB table.
SRC_TABLE	Indicates the name of the table from which data is obtained. This parameter can be set to a name of a common table.

The inserted data cannot be null. If the inserted data is the same as the original data or only the value is different, the inserted data overwrites the original data.
INSERT OVERWRITE is not supported.
You are advised not to concurrently insert data into a table. If you concurrently insert data into a table, there is a possibility that conflicts occur, leading to data insertion failures.
The TIMESTAMP format supports only yyyy-MM-dd hh:mm:ss.
