In SQL Server, the
sys.sql_expression_dependencies system catalog view "Contains one row for each by-name dependency on a user-defined entity in the current database", to quote the docs. One of the returned columns is
referencing_class, of which the docs say this:
referencing_classtinyint Class of the referencing entity.
1 = Object or column
12 = Database DDL trigger
13 = Server DDL trigger
Is not nullable.
However, I'm looking at a database right now in which there is a row with
referencing_class equal to 7. What does 7 mean, and what is the correct list of possible values here?
