this is equal to obj. |
Greater than zero |

備註
If both SqlHierarchyId nodes are null Nothing nullptr unit null 參考 (在 Visual Basic 中為 Nothing) , returns 0.
If one SqlHierarchyId node is null Nothing nullptr unit null 參考 (在 Visual Basic 中為 Nothing) , it is considered to be less than the non- null Nothing nullptr unit null 參考 (在 Visual Basic 中為 Nothing) SqlHierarchyId node.
