Hi Yuechang. I'm assuming that the previous version of Db2 you were running was 11.1 and the latest container is 11.5? I know that there were some changes in the client code that may have changed the way that boolean values were being interpreted. Can you update the Db2 environment variable in your Docker container and restart the database to see if this makes any difference to the results?db2set DB2_ENABLE_BOOL_DESC=NOMy understanding is that in Db2 11.5 this value is set to YES which means that the driver code gets a descriptor that says it is a boolean value where in Db2 11.1 is was NO which means it is returned as an integer value. I have seen this error occur with Python and Jupyter notebooks when using 11.5 and this change fixed the errors.
