如何找到指定数据库中没有聚集索引的所有表？

运行下列查询之前，请使用有效数据库名称替换 <database_name>。

SELECT SCHEMA_NAME(t.schema_id) AS schema_name, t.name AS table_nameFROM sys.tables AS tWHERE 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，可以使用以下示例所显示的 OBJECTPROPERTY 函数。

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

如何找到依赖于指定 CLR 用户定义类型或别名类型的参数？

运行以下查询之前，请使用有效名称替换 <database_name>，并使用有效的架构限定的 CLR 用户定义类型和别名类型名称替换 <schema_name.data_type_name>。 以下查询需要 db_owner 角色的成员身份或者查看数据库中所有依赖列和计算列元数据的权限。

USE <database_name>;GOSELECT OBJECT_NAME(object_id) AS object_name    ,NULL AS procedure_number    ,name AS param_name    ,parameter_id AS param_num    ,TYPE_NAME(p.user_TYPE_ID) AS type_nameFROM sys.parameters AS pWHERE p.user_TYPE_ID = TYPE_ID('<schema_name.data_type_name>')UNION SELECT OBJECT_NAME(object_id) AS object_name    ,procedure_number    ,name AS param_name    ,parameter_id AS param_num    ,TYPE_NAME(p.user_TYPE_ID) AS type_nameFROM sys.numbered_procedure_parameters AS pWHERE p.user_TYPE_ID = TYPE_ID('<schema_name.data_type_name>')ORDER BY object_name, procedure_number, param_num;GO

以下查询返回依赖于 CLR 用户定义类型或别名的参数的受限窄视图，但其结果集对 public 角色可见。 如果您已经将您的用户定义类型的 REFERENCE 权限授予了其他人，并且您没有权限查看其他人使用该类型创建的对象的元数据，则可以使用此查询。

如何找到依赖于指定 CLR 用户定义类型或别名类型的视图、Transact-SQL 函数和 Transact-SQL 存储过程？

运行以下查询之前，请使用有效名称替换 <database_name>，并使用有效的架构限定的 CLR 用户定义类型和别名类型名称替换 <schema_name.data_type_name>。

在函数或过程中定义的参数为隐式架构绑定。 因此，可以使用 sys.sql_dependencies 目录视图查看依赖于 CLR 用户定义类型或别名类型的参数。 过程和触发器均未绑定到架构。 这意味着不会维护任何在过程或触发器的主体中定义的表达式与 CLR 用户定义类型或别名类型之间的依赖关系。 架构绑定视图和架构绑定用户定义函数具有依赖于 CLR 用户定义类型或别名类型的表达式，在 sys.sql_dependencies 目录视图中维护。 不维护类型和 CLR 函数及类型和 CLR 过程之间的依赖关系。

以下查询返回指定 CLR 用户定义类型或别名类型在视图、Transact-SQL 函数和 Transact-SQL 存储过程中的所有架构绑定依赖关系。

如何找到视图的定义？

运行以下查询之前，请使用有效名称替换 <database_name> 和 <schema_name.object_name>。

USE <database_name>;GOSELECT definitionFROM sys.sql_modulesWHERE object_id = OBJECT_ID('<schema_name.object_name>');GO
