Please add test case.

Please add test case.

This fix have float result , we should wait for #8730, and #8730 depends on some code at #8770 , I think we should submit the tests separately after.

It doesn't seem to solve the problem completely, there is still a wrong case ~

    case OLAP_FIELD_TYPE_DATETIME: {
        auto column_int = assert_cast<vectorized::ColumnVector<vectorized::Int64>*>(column);

        for (uint32_t j = 0; j < selected_size; ++j) {
            if (!nullable_mark_array[j]) {
                uint32_t row_idx = j + start;
                auto ptr = reinterpret_cast<const char*>(batch->cell_ptr(row_idx));

                uint64_t value = *reinterpret_cast<const uint64_t*>(ptr);
                vectorized::VecDateTimeValue data(value);
                (column_int)->insert_data(reinterpret_cast<char*>(&data), 0);
            } else {
                column_int->insert_default();
            }
        }
        break;
    }

It seems that the code in row_block2.cpp should also be fixed.

Please add test case.

I will submit a separate pr after this pr merged.

add comment what's the different between create_from_olap_datetime and create_from_normal_datetime. it is default to know the different from the name of function name.
