hem1891 opened a new pull request #25570: [Spark 23519][SQL] create view should work from query with duplicate output columns URL: https://github.com/apache/spark/pull/25570 Before this PR following queries would fail `CREATE TABLE t23519 AS SELECT 1 AS c1 CREATE VIEW v23519 (c1, c2) AS SELECT c1, c1 FROM t23519` This PR checks for duplicate columns from view schema(aliasedSchema) instead of the query output schema(analyzedSchema), allowing such query to work.
