|    2 |

| bitmap_to_string(bitmap_and_not(bitmap_from_string('1,2,3'), bitmap_from_string('3,4,5'))) |
+--------------------------------------------------------------------------------------------+
| 1,2                                                                                        |

mysql> select bitmap_to_string(bitmap_and_not(bitmap_from_string('1,2,3'),bitmap_empty())) ;
+-------------------------------------------------------------------------------+
| bitmap_to_string(bitmap_and_not(bitmap_from_string('1,2,3'), bitmap_empty())) |
+-------------------------------------------------------------------------------+

+-------------------------------------------------------------------------------+

mysql> select bitmap_to_string(bitmap_and_not(bitmap_from_string('1,2,3'),NULL));
+---------------------------------------------------------------------+
| bitmap_to_string(bitmap_and_not(bitmap_from_string('1,2,3'), NULL)) |
+---------------------------------------------------------------------+
| NULL                                                                |
