Hi. What is the best way to store a list of random numbers (like lotto/bingo numbers) and retrieve them? I'd like to store on a Database a number of rows, where each row contains 5-10 numbers ranging from 0 to 90. I will store a big number of those rows. What I'd like to be able is to retrieve the rows that have at least X number in common to a newly generated row.

Example:

[3,4,33,67,85,99]
[55,56,77,89,98,99]
[3,4,23,47,85,91]

Those are on the DB

I will generate this: [1,2,11,45,47,88] and now I want to get the rows that have at least 1 number in common with this one.

The easiest (and dumbest?) way is to make 6 select and check for similar results.

I thought to store numbers with a large binary string like 000000000000000000000100000000010010110000000000000000000000000 with 99 numbers where each number represent a number from 1 to 99, so if I have 1 at the 44th position, it means that I have 44 on that row. This method is probably shifting the difficult tasks to the Db but it's again not very smart.

Any suggestion?
