             Summary: ZetaSQL failed on WITH queries because wrong ref column index calculated in JoinScanWithRefConverter
                 Key: BEAM-10783
                 URL: https://issues.apache.org/jira/browse/BEAM-10783
             Project: Beam
          Issue Type: Bug
          Components: dsl-sql-zetasql
            Reporter: Robin Qiu
            Assignee: Robin Qiu


Some WITH queries, like:

```

WITH t1 AS (select 1 AS k), t2 AS (select 1 AS k), t3 AS (select 1 AS k)
SELECT COUNT(*)
FROM t1 JOIN t3 USING (k)

```

failed on ZetaSQL because how column index is calculated in JoinScanWithRefConverter is not correct.

 

In fact, the other converter responsible for JOINs, JoinScanConverter, has the correct implementation, and that works fine for JOINs that has reference to WITH queries. So I believe we should delete the incorrect JoinScanWithRefConverter class and move to the other one.
