@pengdaqian2020 I just talk with @bb7133 yesterday. I think we can move some check to parser component, and this will make the fix more easily and fully covered with all statement. What do you think about that?

What about implements this validation on parser component?

And there also a bug for convert function:

mysql> select convert('0.0', Decimal(800, 40));
+--------------------------------------------+
| convert('0.0', Decimal(800, 40))           |
+--------------------------------------------+
| 0.0000000000000000000000000000000000000000 |
+--------------------------------------------+

Why all the columns names are empty when error M bigger than D happened?
