             Summary: ColumnValue not backwards compatibile after CALCITE-1040
                 Key: CALCITE-1458
                 URL: https://issues.apache.org/jira/browse/CALCITE-1458
             Project: Calcite
          Issue Type: Bug
          Components: avatica
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Blocker
             Fix For: avatica-1.9.0


[~onpduo] was nice enough to help me debug an issue using the C# driver against Avatica 1.8.1. We could see that a record was being placed into the database, but the C# driver wasn't returning the value.

After inspecting the server, I could see that the row was being returned by the server. Still the client claimed to not know about the value in the row.

Turns out, this was a botched backwards-compatibility issue introduced by CALCITE-1040. When the array_value and scalar_value fields were introduced, the original value field stopped having the values set in it. This caused the C# driver, which was still using that (now deprecated) field to stop seeing any records.

A simple fix to start adding the values for the row into that deprecated field seems to have fixed the issue.
