Description

Query based compaction fails on Tables having complex data types with reserved keywords for columns. The compaction fails while creating a temporary table as it does not quote the columns correctly.

Below are the steps to reproduce the issue.

create table complex_dt_compact2(col1 array<struct<arr_col1:int, `timestamp`:string>>);
insert into complex_dt_compact2 SELECT ARRAY(NAMED_STRUCT('arr_col1',1,'timestamp','2022-07-05 21:51:20.371'));
insert into complex_dt_compact2 SELECT ARRAY(NAMED_STRUCT('arr_col1',2,'timestamp','2022-07-05 21:51:20.371'));
alter table complex_dt_compact2 compact 'major' and wait;

Error:
