Doris> SELECT REGEXP_EXTRACT('foo\nbar', '^(.+)$', 1);
+-----------------------------------------+
| REGEXP_EXTRACT('foo\nbar', '^(.+)$', 1) |
+-----------------------------------------+
|                                         |
+-----------------------------------------+
```

After
```text
Doris> SELECT REGEXP_EXTRACT('foo\nbar', '^(.+)$', 1);
+-----------------------------------------+
| REGEXP_EXTRACT('foo\nbar', '^(.+)$', 1) |
+-----------------------------------------+
| foo
bar                                 |
