Re: Issues with converting update command to trigger

I appreciate this community, thank you for this help. I am trying to watch table: telemetry_log for any insert. Upon any insert on telemetry_log i would like to update the column: device_desc of that newly inserted row with the device_desc from table: id_name_update based on matching device_ids.

Currently the command is running out of a bash script that uses the data remotely.

Here was my most recent attempt:

DROP IF EXISTS TRIGGER add_desc

DELIMITER $$

CREATE TRIGGER add_desc
AFTER insert on telemetry_log
FOR EACH ROW

BEGIN
UPDATE telemetry_log JOIN id_name_update ON telemetry_log.device_id = id_name_update.device_id
SET telemetry_log.device_desc = id_name_update.device_desc
WHERE telemetry_log.devie_desc IS NULL;

end;
$$
delimiter;
