URL: https://github.com/apache/arrow-datafusion/issues/5248
**Describe the bug**
A clear and concise description of what the bug is.
In SQL when ORDER BY an ambiguous column, it doesn't return an error.
**To Reproduce**
Steps to reproduce the behavior:
```sql
❯ select * from test1 t1 join test2 t2 using (a) order by b;
+---+---+---+---+---+
| a | b | c | b | c |
+---+---+---+---+---+
| 1 | 2 | 3 | 2 | 3 |
| 4 | 5 | 6 | 5 | 6 |
+---+---+---+---+---+
2 rows in set. Query took 0.016 seconds.
❯ explain select * from test1 t1 join test2 t2 using (a) order by b;
