   ```
       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.
