Hi everybody,

i ran today in a problem when doing some (too much for me) advanced sql...

What i want to do is something like this:

SELECT
	my_var1,
	my_var2,
	my_function(my_var1, my_var2)
FROM (
	SELECT
		'1',
		'2',
		'3',
		'4'
) AS my_var1_values,
(
	SELECT
		'1',
		'2',
		'3',
		'4'
) AS my_var2_values

In short, i want to calculate the result of the function my_function for
some values of my_var1, cross by some values of my_var2.
These values are not taken in a table, but put in directly.
They are a lot, so i would prefer not to write the whole thing, line
after line. (Let's say 10 values for the first, and 40 for the second =>
400 lines of code to maintain...)

I really don't see how to do this :-/

Any help is heartfully welcome,
David
