res.Check(testkit.Rows("00:00:00.567"))

Because the prefix subtring is undefined when Time convert into Datetime. So better not check the whole row，but the postfix.

resultFieldType.Decimal is not set, is it the expected behavior?

FieldType.Flen = mysql.MaxDatetimeWidthNoFsp + mathutil.Max(lhs.Decimal, rhs.Decimal) => resultFieldType.Flen = mysql.MaxDatetimeWidthNoFsp + maxDecimal

Why need to adjust the flen after types.AggFieldType, is it possible to set flen correctly inside types.AggFieldType

yes, resultFieldType.Decimal is correct

ok

this place will be safer and avoid post-change-after-fix, so we can see other type checks here.

I don't understand why Datetime type does not need to set Decimal, AFAIK, the decimal of type Datetime is 0, and the decimal of type Datetime(3) is 3.

Other type checks check the EvalType here, not the field type, I think types.AggFieldType should guarantee that its result's flen and decimal is set correctly.

I don't understand why Datetime type does not need to set Decimal, AFAIK, the decimal of type Datetime is 0, and the decimal of type Datetime(3) is 3.

Other type checks check the EvalType here, not the field type, I think types.AggFieldType should guarantee that its result's flen and decimal is set correctly.

1.Decimal is correct, the bug caused incorrent length. The decimal is correctly computed by max(lhs.decimal, rhs.decimal) in previous code.
2. resultEvalType := resultFieldType.EvalType(). since we need ensure the resultFieldType.Tp is DateTime neither Time nor Date. so resultFieldType.Tp is used here not resultFieldType.EvalType(). I agree that “types.AggFieldType should guarantee that its result's flen and decimal is set correctly.” But it is complicated, the bug is about the order of execute flow path, types.AggFieldType itself is correct, totally change the order of execute flow path may be dangerous. I think this little change to fix may be sufficient.

Looks like the returned bool value is useless.
