將“自動增量ID字段”添加到並集所有access-sql-query結果

Question

嘗試將新字段“ id字段”添加到Microsoft Access中的簡單聯合所有sql查詢中，如下所示：

SELECT table1.name, table1.age FROM table1
UNION ALL
SELECT table2.name, table2.age FROM table2
UNION ALL
SELECT table3.name, table3.age FROM table3 
;

從1開始自動遞增，這可行嗎？

看看是否可行

SELECT ROW_NUMBER() OVER (ORDER BY name), *
FROM (
SELECT table1.name, table1.age FROM table1
UNION ALL
SELECT table2.name, table2.age FROM table2
UNION ALL
SELECT table3.name, table3.age FROM table3 
) x
