Shubhambhusate opened a new pull request, #53691: URL: https://github.com/apache/spark/pull/53691
### What changes were proposed in this pull request? This PR fixes the DROP operator in pipe syntax (|>) to support qualified column names. ### Why are the changes needed? Previously, the DROP operator in pipe syntax only accepted simple identifiers due to the use of identifierSeq in the grammar. This prevented users from dropping struct fields using qualified names ### Does this PR introduce _any_ user-facing change? Yes. Users can now use qualified column names with the DROP pipe operator.

Test 1: Updated SQL test cases in pipe-operators.sql with positive test for dropping struct fields using qualified names Updated expected results in pipe-operators.sql.out and analyzer-results/pipe-operators.sql.out Test 2: spark.sql(""" | SELECT 2 AS lhs_a, 1 AS lhs_b | |> AS lhs | |> JOIN (VALUES (2, 1)) AS rhs(a, b) | ON lhs.lhs_a = rhs.a | |> Drop lhs.lhs_a | """).show() ### Was this patch authored or co-authored using generative AI tooling?
