Q:

Join tables to concat every possible combination

I have two mysql tables. One with article numbers and one with variants numbers.
No I want to join the tables so have a result table with every possible article/variant combination.
For example:
Article numbers table:
+-----------+-------------+
| ArticleNo | ArticleName |
+-----------+-------------+
|      0001 | Product 1   |
|      0002 | Product 2   |
|      0003 | Product 3   |
+-----------+-------------+

Variants numbers table:
+-----------+-------------+
| VariantNo | VariantName |
+-----------+-------------+
|      1001 | Variant 1   |
|      1002 | Variant 2   |
|      1003 | Variant 3   |
+-----------+-------------+

Result table:
+----------+---------------------+
| ResultNo |     ResultName      |
+----------+---------------------+
| 00011001 | Product 1 Variant 1 |
| 00011002 | Product 1 Variant 2 |
| 00011003 | Product 1 Variant 3 |
| 00021001 | Product 2 Variant 1 |
| 00021002 | Product 2 Variant 2 |
| 00021003 | Product 2 Variant 3 |
| 00031001 | Product 3 Variant 1 |
| 00031002 | Product 3 Variant 2 |
| 00031003 | Product 3 Variant 3 |
+----------+---------------------+

A:

You can write Directly:
SELECT  CONCAT(a.ArticleNo,v.VariantNo) as ResultNo, 
CONCAT(a.ArticleName,v.VariantName) as ResultName 
FROM Article a,Variants v

It will produce Cross Join
