Tpt opened a new pull request, #18956: URL: https://github.com/apache/datafusion/pull/18956
It gives a name (the table name) to each `WorkTable`. This way `WorkTableExec` can recognize its own `WorkTable` Note that it doesn't allow multiple occurrences of the same CTE name: it's not possible to implement things like "join with itself" correctly with only the work table. ## Which issue does this PR close? - Closes #18955. ## Rationale for this change Support nested recursive CTEs without co-recursion. This is useful to e.g. implement SPARQL or other graph query languages. ## What changes are included in this PR? ## Are these changes tested? Yes! There is a nested recursive query in the test file ## Are there any user-facing changes? Nested recursive queries are now allowed instead of failing with a "not implemented" error -- This is an automated message from the Apache Git Service.
