SQL Match exact set of values between two tables - sql

Question

Okay, this is a little hard to explain, but I'll give it my best shot.
I've got two tables, we'll call them table1 and table2. table1 looks something like this:
ID | CampaignID | Package | GroupID
1 | 1 | 1 | 1
2 | 1 | 1 | 2
3 | 1 | 2 | 2
4 | 2 | 1 | 3
5 | 2 | 2 | 3
6 | 2 | 3 | 3
etc
Table2 looks something like this:
ID | ClientID | ClientName | Package | OrderID
1 | 1111 | John Smith | 1 | 155
2 | 1111 | John Smith | 2 | 155
4 | 2222 | Dave Jones | 1 | 177
5 | 2222 | Dave Jones | 2 | 178
6 | 2222 | Dave Jones | 3 | 179
What I'm trying to do, is see if for example, John Smith has any Orders with sets of packages that match one of the Campaign Groups in table1. For the above example, John Smith's order 155 would match CampaignID 1, GroupID 2. Dave Jones's order 177 matches CampaignID 1, GroupID 1. However orders 178 and 179 don't match anything. So each set of packages in an order need to contain all the packages for a given group in order to match it
For the purposes of the select statement I have the client's id along with the orderID, and I'm simply trying to see if the packages in his order match the criteria for any campaigns.
I know I probably haven't explained this too well, so let me know what needs clarifying.
EDIT:
If lets say we search for orderID 155, clientID 1111, then the desired result would be:
CampaignID | GroupID
1 | 2
Perhaps given that GroupID 1 also qualifies, it could return the groupID that qualifies with the largest number of packages.

Answer 1

Is this , what u want?
select table1.CampaignID from Table2
left join table1 on table1.Package =table2.Package
where Table2.ClientID =#ClientID
and Table2.OrderID =#OrderID

Answer 2

I think I figured it out:
SELECT top 1 pcr1.GroupID FROM table1 pcr1
Where Not Exists (Select CampaignID from table1 as pcr2
where CampaignID = #campaignID and pcr2.GroupID= pcr1.GroupID Except
Select t2.Package from table2 as t2 where t2.OrderID = #ordID)
GROUP BY pcr1.GroupID
ORDER BY COUNT(pcr1.GroupID) DESC
Given a known order and a campaign the client is trying to apply for, this gives me the group id that best matches the given order (in regard to packages), if any exists. And just because people seem to be asking, the way the tables appear here aren't exactly the way they're implemented, it's just a simplified equivalent for the purposes of this question.

Here is my Linkedin Article with a more in depth explaination:

CREATE TABLE Campaign(
ID INT,
CampaignID INT,
Package INT,
GroupID INT)
CREATE TABLE ClientOrder(
ID INT,
ClientID INT,
ClientName VARCHAR(20),
Package INT,
OrderID INT)
INSERT Campaign
(ID, CampaignID, Package, GroupID)
VALUES
(1, 1, 1, 1)
,(2, 1, 1, 2)
,(3, 1, 2, 2)
,(4, 2, 1, 3)
,(5, 2, 2, 3)
,(6, 2, 3, 3)
INSERT ClientOrder
(ID, ClientID, ClientName, Package, OrderID)
VALUES
(1, 1111, 'John Smith', 1 , 155)
,(2, 1111, 'John Smith', 2 , 155)
,(4, 2222, 'Dave Jones', 1 , 177)
,(5, 2222, 'Dave Jones', 2 , 178)
,(6, 2222, 'Dave Jones', 3 , 179)
The query:
SELECT CO.ClientName, CampaignID
FROM ClientOrder AS CO
JOIN Campaign as C1
ON CO.Package = C1.Package
GROUP BY CO.ClientName, CampaignID
HAVING COUNT(CO.Package) = (
SELECT COUNT(Package)
FROM Campaign C2
WHERE C1.CampaignID = C2.CampaignID)
Results:
ClientName CampaignID
-------------------- -----------
Dave Jones 1
John Smith 1
Dave Jones 2
