Server 3.2.3.0 JDBC returns syntax error when a comment is added

[richwxd]

ALTER STABLE device_property MODIFY COLUMN event_time timestamp COMMENT '上报时间';

报错 DB error: syntax error near "comment '上报时间';" (0.001009s)

原始表例子

CREATE STABLE IF NOT EXISTS device_property ( event_time timestamp, motdcvoltage2 FLOAT, motdccurrent2 FLOAT) TAGS (device_id NCHAR(50));
