指定したデータベースのクラスター化インデックスを持たないすべてのテーブルの検索方法How do I find all the tables that do not have a clustered index in a specified database?

次のクエリを実行する前に置き換える<database_name>有効なデータベース名を使用します。Before you run the following queries, replace <database_name> with a valid database name.

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  
  

または、使用することができます、OBJECTPROPERTY次の例に示すように機能します。Or, you can use the OBJECTPROPERTY function as shown in the following example.

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

指定された CLR ユーザー定義型または別名型に依存するパラメーターを検出する方法はありますかHow do I find the parameters that depend on a specified CLR user-defined type or alias type?

次のクエリの <database_name> を有効な名前に置き換え、<schema_name.data_type_name> をスキーマ修飾の CLR ユーザー定義型または別名型の有効な名前に置き換えてから、クエリを実行します。Before you run the following query, replace <database_name> with a valid name and <schema_name.data_type_name> with a valid, schema-qualified CLR user-defined type, alias type name. 次のクエリがメンバーシップが必要です、 db_ownerロールまたはすべての依存列および計算列を表示するアクセス許可、データベース内のメタデータ。The following query requires membership in the db_owner role or permissions to see all dependent column and computed column metadata in the database.

USE <database_name>;

ビュー、TRANSACT-SQL 関数、および指定された CLR ユーザー定義型または別名型に依存する TRANSACT-SQL ストアド プロシージャの検索方法How do I find the views, Transact-SQL functions, and Transact-SQL stored procedures that depend on a specified CLR user-defined type or alias type?

次のクエリの <database_name> を有効な名前に置き換え、<schema_name.data_type_name> をスキーマ修飾の CLR ユーザー定義型または別名型の有効な名前に置き換えてから、クエリを実行します。Before you run the following query, replace <database_name> with a valid name and <schema_name.data_type_name> with a valid, schema-qualified CLR user-defined type, alias type name.

関数またはプロシージャで定義されているパラメーターは、暗黙的に、スキーマ バインドです。The parameters defined in a function or procedure are implicitly schema bound. CLR ユーザー定義型または別名型に依存するパラメーターを表示してを使用して、そのため、 sys.sql_dependenciesカタログ ビューです。Therefore, parameters that depend on a CLR user-defined type or alias type can be viewed by using the sys.sql_dependencies catalog view. プロシージャとトリガーはスキーマ バインドではありません。Procedures and triggers are not schema bound. つまり、プロシージャやトリガーの本体で定義されている式と、CLR ユーザー定義型または別名型の間の依存関係は保守されません。This means that dependencies between any expression defined in the body of the procedure or trigger and a CLR user-defined type or alias type is not maintained. スキーマ バインド ビューと CLR ユーザー定義型に依存する式を持つユーザー定義関数がスキーマにバインドされている、または別名型に保持されます、 sys.sql_dependenciesカタログ ビューです。Schema bound views and schema bound user-defined functions that have expressions that depend on a CLR user-defined type or alias type are maintained in the sys.sql_dependencies catalog view. 型と CLR 関数や CLR プロシージャとの間の依存関係は保持されません。Dependencies between types and CLR functions and CLR procedures are not maintained.

次のクエリは、指定された CLR ユーザー定義型または別名型に関して、ビュー、Transact-SQLTransact-SQL 関数、および Transact-SQLTransact-SQL ストアド プロシージャ内でスキーマにバインドされた依存関係をすべて返します。The following query returns all schema-bound dependencies in views, Transact-SQLTransact-SQL functions, and Transact-SQLTransact-SQL stored procedures for a specified CLR user-defined type or alias type.
