> The pipe syntax DROP operator currently fails with a parse error when trying
> to drop nested struct fields using qualified names (e.g., `drop col.i1`).
> *Current Behavior:*
> >>> spark.sql("""
> ... CREATE OR REPLACE TEMP VIEW st AS
> ... SELECT 1 as x, named_struct('i1', 2, 'i2', 3) as col
> ... """)
> >>> spark.sql("""
> ... TABLE st
> ... |> DROP col.i1
> ... """)
> Error: PARSE_SYNTAX_ERROR: Syntax error at or near '.'
> *Expected Behavior:*
> >>> spark.sql("""
> ... TABLE st
> ... |> DROP col.i1
> ... """)
> Should succeed and return:
> ||x ||col||
> |{{1}}|{{{i2: 3}}}|
