Contributor guide
Research direction
The issue shows screenshots of an SDK query returning empty results versus a command query finding data. Investigate the pre-aggregation table logic in the OpenMLDB codebase, likely in the query execution or SDK client layers. Compare the SDK query path with the command-line query path to identify where data is being filtered or lost. Reproduce the issue locally to understand the discrepancy.
