shubham_bhusate updated SPARK-54914:
------------------------------------
Description:
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
... """)
DataFrame[]
>>> 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} |
+---+--------+
