问题
I have two tables in my Access-database. They look something like this:
Table1
+--------------+----------+----------+----------+
| Kabelnummer | Column1 | Column2 | Column3 |
+--------------+----------+----------+----------+
| 1 | x | x | x |
+--------------+----------+----------+----------+
| 2 | x | x | x |
+--------------+----------+----------+----------+
| 3 | x | x | x |
+--------------+----------+----------+----------+
| 4 | x | x | x |
+--------------+----------+----------+----------+
table2
+--------------+----------+----------+----------+
| Kabelnummer | Column1 | Column2 | Column3 |
+--------------+----------+----------+----------+
| 1 | x | x | x |
+--------------+----------+----------+----------+
| 2 | x | x | x |
+--------------+----------+----------+----------+
| 3 | x | x | x |
+--------------+----------+----------+----------+
| 4 | x | x | x |
+--------------+----------+----------+----------+
I need a query that gives me 1 table with the data from table1 added to the data from table2:
TableTotal
+--------------+----------+----------+----------+
| Kabelnummer | Column1 | Column2 | Column3 |
+--------------+----------+----------+----------+
| 1 | x | x | x |
+--------------+----------+----------+----------+
| 2 | x | x | x |
+--------------+----------+----------+----------+
| 3 | x | x | x |
+--------------+----------+----------+----------+
| 4 | x | x | x |
+--------------+----------+----------+----------+
| 1 | x | x | x |
+--------------+----------+----------+----------+
| 2 | x | x | x |
+--------------+----------+----------+----------+
| 3 | x | x | x |
+--------------+----------+----------+----------+
| 4 | x | x | x |
+--------------+----------+----------+----------+
The names "Column1", "Column2" and "Column3" are the same in both tables
回答1:
SELECT *
FROM Table1
UNION
SELECT *
FROM table2;
回答2:
The question asks for non-distinct values while the current answers provide distinct values. The method below provides non-distinct values such that
SELECT *
FROM Table1
UNION ALL
SELECT *
FROM table2;
which is often more efficient than the union method, particularly with large data sets (not having to compute the distinct).
回答3:
If your goal is to append the second table to the first one, it can be achieved this way
INSERT INTO TABLE1 SELECT * FROM TABLE2;
The caveat with these other queries is that yes, they do the job, but create a third table with the joined data.
