Query

select con.[name] as constraint_name,
    schema_name(t.schema_id) + '.' + t.[name]  as [table],
    col.[name] as column_name,
    con.[definition],
    case when con.is_disabled = 0
        then 'Active'
        else 'Disabled'
        end as [status]
from sys.check_constraints as con
    left outer join sys.objects as t
        on con.parent_object_id = t.object_id
    left outer join sys.all_columns as col
        on con.parent_column_id = col.column_id
        and con.parent_object_id = col.object_id
order by con.name
