ygf11 opened a new issue, #4210:
URL: https://github.com/apache/arrow-datafusion/issues/4210
**Describe the bug**
When the two table both has `c0`, then the following sql will work:
```sql
❯ explain select c0 from test0, test1;
+---------------+-----------------------------------------------------------------------------------------------------+
| plan_type | plan
|
+---------------+-----------------------------------------------------------------------------------------------------+
| logical_plan | Projection: test0.c0
|
| | CrossJoin:
|
| | TableScan: test0 projection=[c0]
|
| | TableScan: test1 projection=[c0]
|
```
The projection part of this sql is not clear, datafusion should throw an
error.
**To Reproduce**
Create two table test0 and test1, which both contain `c0`.
Run sql `explain select c0 from test0, test1;`
**Expected behavior**
