sp_depends (Transact-SQL)

Displays information about database object dependencies, such as the views and procedures that depend on a table or view, and the tables and views that are depended on by the view or procedure. References to objects outside the current database are not reported.

Ważne:
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use sys.dm_sql_referencing_entities and sys.dm_sql_referenced_entities instead.
