sysname

Object name.

object_id

int

Object identification number. Is unique within a database.

TR = SQL trigger

UQ = UNIQUE constraint

schema_id

For all schema-scoped system objects that included with SQL Server, this value will always be in (schema_id('sys'), schema_id('INFORMATION_SCHEMA'))

parent_object_id

0 = Not a child object.
