Here’s a query to find all foreign keys for a table, both keys that reference the specified table, and keys where the table is the child. In SSMS, you can only see the keys for a table where the table is on the child end.
declare @TableName nvarchar(128) = 'Person' select t.name as TableName, rt.name as ReferencedTableName, f.name as ForeignKeyName, f.is_disabled, f.is_not_trusted from sys.foreign_keys as f join sys.tables as t on t.object_id = f.parent_object_id join sys.tables as rt on rt.object_id = f.referenced_object_id where t.name = @TableName or rt.name = @TableName order by t.name, rt.name, f.name
