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:*
sql
CREATE TABLE st(x INT, col STRUCT<i1:INT, i2:INT>);
INSERT INTO st VALUES (1, (2, 3));
TABLE st |> drop col.i1;
Error: PARSE_SYNTAX_ERROR: Syntax error at or near '.'
*{*}Expected Behavior:{*}*
sql
TABLE st |> drop col.i1
Should succeed and return:
+---+--------+
| x| col|
+---+--------+
| 1|\{i2: 3} |
+---+--------+
