Management Studio gebruikt het volgende bij het bepalen van "Systeemobjecten" waarbij "tbl" sys.tables is:
CAST(
case
when tbl.is_ms_shipped = 1 then 1
when (
select
major_id
from
sys.extended_properties
where
major_id = tbl.object_id and
minor_id = 0 and
class = 1 and
name = N'microsoft_database_tools_support')
is not null then 1
else 0
end
AS bit) AS [IsSystemObject]
