如何? 尋找指定資料庫中沒有叢集索引的所有數據表？

執行下列查詢之前，請將 取代 <database_name> 為有效的資料庫名稱。

SELECT SCHEMA_NAME(t.schema_id) AS schema_name, t.name AS table_name  
FROM sys.tables AS t  
WHERE NOT EXISTS   
   (  
     SELECT * FROM sys.indexes AS i  
     WHERE i.object_id = t.object_id  
     AND i.type = 1  -- or type_desc = 'CLUSTERED'  
   )  
ORDER BY schema_name, table_name;  
GO

或者，您可以使用 函 OBJECTPROPERTY 式，如下列範例所示。

USE <database_name>;  
GO  
SELECT SCHEMA_NAME(schema_id) AS schema_name, name AS table_name  
FROM sys.tables   
WHERE OBJECTPROPERTY(object_id,'TableHasClustIndex') = 0  
ORDER BY schema_id, name;  
GO

如何? 尋找指定架構中包含的實體的所有擁有者？

執行下列查詢之前，請將 和 <schema_name> 取代<database_name>為有效的名稱。

USE <database_name>;

    ,USER_NAME(OBJECTPROPERTY(object_id, 'OwnerId')) AS owner_name  
    ,name   
FROM sys.objects WHERE SCHEMA_NAME(schema_id) = '<schema_name>'  
UNION   
SELECT 'TYPE' AS entity_type  
    ,USER_NAME(TYPEPROPERTY(SCHEMA_NAME(schema_id) + '.' + name, 'OwnerId')) AS owner_name  
    ,name   
FROM sys.types WHERE SCHEMA_NAME(schema_id) = '<schema_name>'   
UNION  
SELECT 'XML SCHEMA COLLECTION' AS entity_type

執行下列查詢之前，請將 取代為有效的名稱，並以<schema_name.data_type_name>有效的架構限定 CLR 使用者定義類型、別名類型名稱取代 <database_name> 。

函式或程式中定義的參數是隱含架構系結。 因此，可以使用 sys.sql_dependencies 目錄檢視來檢視相依於 CLR 使用者定義類型或別名類型的參數。 程式和觸發程式不是架構系結。 這表示不會維護程式或觸發程式主體中定義之任何表達式與CLR用戶定義型別或別名類型之間的相依性。 架構系結檢視和架構系結使用者定義函式，其表達式相依於 CLR 使用者定義類型或別名類型，會在 sys.sql_dependencies 目錄檢視中維護。 不會維護類型和 CLR 函式與 CLR 程式之間的相依性。

下列查詢會針對指定的CLR使用者定義類型或別名類型，傳回檢視表、Transact-SQL 函數和 Transact-SQL 預存程式中的所有架構系結相依性。
