たぶん、最初の答えのひねりはあなたのためにそれをすることができますか？：

SELECT 
    sc.name + '.' + t.name as tableName,
    OBJECT_NAME(fkc.constraint_object_id) AS [FKey-Name],
    OBJECT_NAME(fkc.referenced_object_id) ReferencedTable, 
c.name as ColumnName
, i.name AS ReferencedKeyName
FROM    sys.foreign_key_columns fkc
JOIN    sys.index_columns ic ON ic.object_id = fkc.parent_object_id
    AND ic.column_id = fkc.parent_column_id
JOIN    sys.indexes i ON i.index_id = ic.index_id
    AND i.object_id = ic.object_id
JOIN sys.columns c ON c.object_id = ic.object_id
    AND c.column_id = ic.column_id  
JOIN    sys.tables t ON t.object_id = c.object_id
JOIN    sys.schemas sc ON sc.schema_id = t.schema_id
WHERE   t.is_ms_shipped = 0
ORDER BY tableName, OBJECT_NAME(fkc.constraint_object_id), columnName

これは、必要なことを行うクエリです。

SELECT 
sc.name + '.' + t.name as tableName,
i.name as indexName,
c.name as columnName
FROM sys.foreign_key_columns fkc
JOIN sys.index_columns ic ON ic.object_id = fkc.parent_object_id
    AND ic.column_id = fkc.parent_column_id
JOIN sys.indexes i ON i.index_id = ic.index_id
    AND i.object_id = ic.object_id
JOIN sys.columns c ON c.object_id = ic.object_id
    AND c.column_id = ic.column_id  
JOIN sys.tables t ON t.object_id = c.object_id
JOIN sys.schemas sc ON sc.schema_id = t.schema_id
where t.is_ms_shipped = 0
ORDER BY tableName, indexName, columnName
