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
SELECT *
FROM Table1
UNION
SELECT *
FROM table2;
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).
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.
