Question

I want to perform a cartesian product between two SELECT statements as

SELECT 1, 2     INNER JOIN     SELECT 3, 4 ;

I expect the result to be every combination of (1,2) with (3,4), like:

1  3
2  3
1  4
2  4

Answer 1

You can use the CROSS JOIN clause

SELECT MyTable1.Col1, MyTable2.Col2
FROM MyTable1
CROSS JOIN MyTable2

where MyTable1 has two rows containing 1 and 2; and MyTable2 has two rows containing 3 and 4.
