如何通过MS Access上的查询进行表比较后，如何向列添加值

Question

正如我在这篇文章的标题中所提到的，我正在搜索一种方法，通过查询在Access的表字段上写入，值“DELETED”或“INSERTED”基于2个相似表的比较。 这是我的问题：

SELECT A.[Codice T_CAD], A.[Codice Comp], A.Quantita, A.Desc_ITA, IIf(IsNull(B.[Codice ProJ]),"DELETED","INSERTED")
FROM [Tabella Ponte Distinte 4_0] A
LEFT JOIN qdfImport40RecuperaDistinteComponenti B ON (A.[Codice Comp] = B.[Codice ProJ]) AND (A.[Codice T_CAD] = B.Codice_SEZ)
WHERE (((B.[Codice ProJ]) Is Null));

查询返回3条记录：

Codice T_CAD      Codice Comp      Quantita Desc_ITA                  Status
TNAA9012AA03115   ARR0004267007           1 PIANO 50X113              DELETED
TNAA9012AA03115   ARR0004269007           1 PIANO 66X113              DELETED
TNAA9012AA03115   11001317                1 Esagono betulla 9 mm      DELETED

而不是：

Codice T_CAD      Codice Comp      Quantita Desc_ITA                 Status
TNAA9012AA03115   ARR0004267007           1 PIANO 50X113             INSERTED
TNAA9012AA03115   ARR0004269007           1 PIANO 66X113             INSERTED
TNAA9012AA03115   11001317                1 Esagono betulla 9 mm     DELETED

因为表A与第二个查询相比有2个新记录和1个删除。 如何管理受查询返回相应值的记录状态？

编辑：这些是表的结构：
