Search array with logical condition - sql

Question

I have integer array for which I have to check whether items meet the logical condition.
For example:
array: [1, 4, 17, 22, 45]
condition: 1 AND 17 AND (22 OR 49)
How to check that elements of array fulfill the condition.
I have elements of array stored in DB as rows with common identifier:
ID_1 | 1
ID_1 | 4
ID_1 | 17
ID_1 | 22
ID_1 | 45
If someone has any idea how to check that those values meet condition through SQL or search across array I would be grateful.

Answer 1

Maybe something like this:
Module StartupModule
Sub Main()
Dim nums() As Integer = {1, 4, 17, 22, 45}
Dim hasNumbers As Func(Of Integer(), Boolean) = Function(arr)
Return arr.Contains(1) AndAlso arr.Contains(17) AndAlso (arr.Contains(22) OrElse arr.Contains(49))
End Function
Dim result As Boolean = hasNumbers(nums)
Console.WriteLine(result)
Console.ReadLine()
End Sub
End Module
EDIT
It won't do as just now read that condition would be anything. So I would use expression trees.

Answer 2

I assume that you want to find invoices containing item id 1 AND 17 AND (22 OR 49). Then you can do
SELECT invoice_id
FROM items
WHERE item_id IN (1, 17, 22)
GROUP BY invoice_id
HAVING COUNT(*) = 3
UNION
SELECT invoice_id
FROM items
WHERE item_id IN (1, 17, 49)
GROUP BY invoice_id
HAVING COUNT(*) = 3
This works only if the item_ids are unique per invoice.

Answer 3

I found a solution in the reverse logic. For each element in a condition that represents an item (not braces or logical operand, so integer) I checked whether it is element of array. If it is then it's replaced with true, otherwise with fasle.
So I get something like this:
array: [1, 4, 17, 22, 45]
original conditions
condition A: 1 AND 17 AND (22 OR 49)
condition B: 17 AND 45
will turn into
condition A: true AND true AND (true OR false)
condition B: true AND true
Then I just need to make function that will evaluate string with boolean expression into true or false.
Here is example how to evaluate logical expression.
So I didnt test array with condition then check if items in condition exist or not in array and replace them with true/false. With that I got a logical expression that should be evaluated.
