> Key: CALCITE-3840
> URL: https://issues.apache.org/jira/browse/CALCITE-3840
> Project: Calcite
> Issue Type: Bug
> Components: jdbc-adapter
> Affects Versions: 1.21.0
> Reporter: Christian Beikov
> Priority: Major
> Fix For: 1.23.0
>
>
> Rendering a VALUES relnode to e.g. PostgreSQL will produce \{{FROM
> (VALUES((1))) AS t(col_alias)}} where "t" is a static alias. When e.g.
> joining with such a VALUES, the RelToSqlConverter tries to re-alias this with
> a unique alias, but fails because it produces \{{FROM (VALUES((1))) AS
> t(col_alias) AS newAlias}}.
> The fix is to replace the static table alias instead.
