peter-toth opened a new pull request, #36146: URL: https://github.com/apache/spark/pull/36146
### What changes were proposed in this pull request? Fix CTE resolution in non-legacy, non-command cases with collecting already resolved outer CTEs. These outer CTE definitions are requires to property define inner CTEs. ### Why are the changes needed? Fix a bug introduced in 3.2.0 with [SPARK-36447](https://issues.apache.org/jira/browse/SPARK-36447). Currently the following query can't resolve `t1` in the inner CTE. After this PR the following query returns the expected value. ``` WITH t1 AS (SELECT 1), t2 AS ( WITH t3 AS ( SELECT * FROM t1 ) SELECT * FROM t3 ) SELECT * FROM t2; ``` ### Does this PR introduce _any_ user-facing change? Yes, the query works again. ### How was this patch tested? Added new test case. -- This is an automated message from the Apache Git Service.
