如何获取所有SQL Server默认值和规则的名称

Question

I'm trying to write a query to get the names of all Rules and Defaults in the database so I can programatically drop all of them from a database without having to know their names.

They don't seem to be contained in sys.objects , though - so where can I find them?

Answer 1

Try this

SELECT *
FROM   sys.objects
WHERE  type = 'r' -- to filter rules
        OR ( parent_object_id = 0 -- to restrict default constraints 
             AND type = 'd' ) -- to filter defaults
