Eric Pai created IOTDB-2137:
-------------------------------
Summary: Incorrect column number in UDTFDataSet
Key: IOTDB-2137
URL: https://issues.apache.org/jira/browse/IOTDB-2137
Project: Apache IoTDB
Issue Type: Bug
Components: Core/Query
Reporter: Eric Pai
Assignee: Eric Pai
Fix For: master branch
There's a method:
QueryDataSet.getColumnNum() which returns the amount of columns in a query set.
The default implentation is to count the original paths in the input. However,
in a UDTF query, the column is related to the expressions list, not the raw
timeseries path.
