Hi,
I have members that belongs to different group and other member can be in more than one group but in Hierarchy.
I.E Group One, these members are only found in this group
Group Two, Some, not all, of these members can also be found in Group One
Group Three, Some, not all, of these members can also be found in Group Two
Group Four, Some, not all, of these members can also be found in Group Three
All of these are found in these three Tables,
CREATE TABLE [dbo].[Groups](
[GroupID] [tinyint] NOT NULL,
[GroupName] [varchar](50) NOT NULL
)
CREATE TABLE [dbo].[Subscriptions](
[SubscriptionID] [bigint] IDENTITY(1000,1) NOT NULL,
[Status] [int] NOT NULL,
[StartDate] [datetime] NULL,
[ActivationDate] [datetime] NULL,
[EndDate] [datetime] NULL,
[PersonID] [bigint] NULL,
[GroupID] [tinyint] NULL)
CREATE TABLE [dbo].[HD_PERSON](
[PersonID] [bigint] IDENTITY(1,1) NOT NULL,
[FirstName] [varchar](100) NULL,
[LastName] [varchar](200) NULL)
So if I join these table and SELECT DISTINCT, if PersonID from GROUP 2 is also in Group 1, that person will also be returned.
So I want all PersonID in that Hierarchy, All of Group 1 members, the Group 2 but not in Group until the last Group.
Please help

After 390+ visits, you should know how to post data to a forum to get the best results. I have a link in my signature if you need a reminder.
Just reading the description, it sounds like MIN(GroupID) should give you what you need.

The first link in your signature line takes us to an MSDN site for "ORDER BY".

For this, I'd use a many-to-many table with a HierarchyID datatype column that allowed each person to be in multiple hierarchies.
Or will you have depths greater than about 400 nodes? HierarchyID works well above that, but can't really go below that.
