Before you run the following query, replace with a valid name and with a valid, schema-qualified CLR user-defined type, alias type name.

The parameters defined in a function or procedure are implicitly schema bound. Therefore, parameters that depend on a CLR user-defined type or alias type can be viewed by using the sys.sql_dependenciescatalog view. Procedures and triggers are not schema bound. 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. 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. Dependencies between types and CLR functions and CLR procedures are not maintained.
The following query returns all schema-bound dependencies in views, Transact-SQL functions, and Transact-SQL stored procedures for a specified CLR user-defined type or alias type.
