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。

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>。

Transact-SQL
USE <database_name>;
GO
SELECT definition
FROM sys.sql_modules
WHERE object_id = OBJECT_ID('<schema_name.object_name>');
GO


或者,可以使用以下示例所显示的 OBJECT_DEFINITION 函数。

Transact-SQL
USE <database_name>;
GO
SELECT OBJECT_DEFINITION (OBJECT_ID('<schema_name.object_name>')) AS ObjectDefinition;
GO
