URL: https://github.com/apache/doris/pull/68307
```sql
CREATE TABLE t (
id INT,
s STRUCT<a:INT COMMENT "doc a", b:TEXT COMMENT "doc b">
) DUPLICATE KEY(id) DISTRIBUTED BY HASH(id) BUCKETS 1
PROPERTIES ("replication_num" = "1");
1. SHOW CREATE TABLE t;
-- before
`s` struct<a:int,b:text> NULL
-- after
`s` struct<a:int comment "doc a",b:text comment "doc b"> NULL
CREATE TABLE LIKE and the CCR binlog re-parse this text, so the comments
were not just hidden, they were gone from the new table.
2. SELECT column_type FROM information_schema.columns WHERE table_name = 't'
AND column_name = 's';
-- before
struct<int(11),string>
-- after
struct<a:int(11),b:string>
