Description
1.老版本是11.3,加了测点
2.后面升级到11.5后,在次修改测点(sql=ALTER timeseries {} UPSERT ALIAS={} TAGS(name='{}',dir='{}',exName='{}',description='{}',unit='{}') ATTRIBUTES(minValue={},maxValue={})),sessionPool.executeNonQueryStatement(sql)修改是正常提交了,但完成后根据tag查不到数据
3.实在没有办法就删除了测点 delete timeseries,重新添加测点
4.再次查询,发现可以正常了
Contributor guide
Research direction
Reproduce the upgrade from IoTDB 11.3 to 11.5, then use sessionPool.executeNonQueryStatement with the reported ALTER timeseries statement and query by tag after restarting. Confirm that modifying an existing measurement preserves tag-based query results, while deleting and recreating it remains a comparison case.
