In SQL Server, How Do I List all the Constraints by Table or by Column Name?

This one will order the contraints by table:

Select SysObjects.[Name] As [Contraint Name] ,Tab.[Name] as [Table Name],Col.[Name] As [Column Name]
 From SysObjects Inner Join (Select [Name],[ID] From SysObjects Where XType = 'U') As Tab
On Tab.[ID] = Sysobjects.[Parent_Obj]
Inner Join sysconstraints On sysconstraints.Constid = Sysobjects.[ID]
Inner Join SysColumns Col On Col.[ColID] = sysconstraints.[ColID] And Col.[ID] = Tab.[ID]
order by Tab.[Name]

This one will order the contraints by column:

Select SysObjects.[Name] As [Contraint Name] ,Tab.[Name] as [Table Name],Col.[Name] As [Column Name]
 From SysObjects Inner Join (Select [Name],[ID] From SysObjects Where XType = 'U') As Tab
On Tab.[ID] = Sysobjects.[Parent_Obj]
Inner Join sysconstraints On sysconstraints.Constid = Sysobjects.[ID]
Inner Join SysColumns Col On Col.[ColID] = sysconstraints.[ColID] And Col.[ID] = Tab.[ID]
order by Col.[Name]
