How Do I Show Both Parents of The Same Child

I have two tables, one with the names of adults and the other with the name of children. In the Children's table there are two columns, ParentID (Not Nullable) and OtherParentID (Nullable). I would like to query the tables so that when either of the parents IDs are presented as parameters, the other can show as the spouse or partner along with the related children from the Players table.

Is this possible with the tables I have? Or do I need to take a different approach?

USE [DBName]
GO

/****** Object:  Table [dbo].[ParentGuardian]    Script Date: 03/09/2011 00:00:42 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[ParentGuardian](
	[ParentID] [int] IDENTITY(1,1) NOT NULL,
	[FirstName] [nvarchar](20) NOT NULL,
	[LastName] [nvarchar](20) NOT NULL,
	[Gender] [nvarchar](6) NOT NULL,
	[Birthdate] [date] NOT NULL,

)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[ParentGuardian] ADD  CONSTRAINT [DF_ParentGuardian_State]  DEFAULT (N'TX') FOR [State]
GO



USE [DBName]

GO

ALTER TABLE [dbo].[Players]  WITH CHECK ADD  CONSTRAINT [FK_Players_ParentGuardian] FOREIGN KEY([ParentID])
REFERENCES [dbo].[ParentGuardian] ([ParentID])
ON DELETE CASCADE
GO

ALTER TABLE [dbo].[Players] CHECK CONSTRAINT [FK_Players_ParentGuardian]
GO

I have an asp.net vb project in vs 2010 where I am trying show this data in 2 gridview controls. One has a list of Adult names and the other uses the ParentID to display the names of the Junior Players along with the Other Parent. I can get them to work on ONE parent, but not the OtherParentID. I need the Junior Players to show no matter which parent name is selected along with the ParentID or OtherParentID aliased as "Spouse or Partner".

Hi,
 
This should give you the desired results.


select p.Firstname as Child, pa.FirstName as Parent, ps.FirstName as Spouse
FROM 
Players p 
INNER JOIN ParentGuardian pa 
ON p.parentid = pa.parentid 
LEFT OUTER JOIN ParentGuardian ps 
ON p.OtherParentID = ps.parentid

Cool! That does work, even when I add the WHERE and OR for the parameters
