Hi, this is your first issue in IoTDB project. Thanks for your report. Welcome to join the community!

0.13 is too old and no longer maintained. If you are looking for better support of DBeaver, please use the latest 2.x version.

hi @HTHou , thanks for your tips. I just didn't notice the higher version. I see the 2.x is still in beta. So I choose 1.3.3.

But there are still some potentials isseus:

By the way, errors are still there with iotdb-jdbc-2.0.1-beta-jar-with-dependencies.jar

Below comes from DBeaver

Below comes from atest

Yes, 1.3.3 still has the issue you pointed out. You may need to try the master branch, which will be released soon. @CritasWang

For better support of DBeaver, I think you need to use the table model, which is included in IoTDB 2.x. https://iotdb.apache.org/UserGuide/latest-Table/QuickStart/QuickStart_apache.html

Thanks for telling me more details. For me, I prefer to keep the orignal feature of IoTDB. I will try to implement it in atest-ext-store-iotdb.
