The ErrorMessage column does not come through for SWQL queries on the ResponseTime view, and attempting to access it causes an error. The query below works while the rt.errormessage column is commented out. Add it back in and you'll get an error. We would like to test for text present / absent in the error message as a way of filtering / highlighting certain issues.
select rt.transactionid as t_id, rt.datetimeutc, AddDate('minute', -300, rt.datetimeutc) as LocalBusinessTime
, rt.minduration
, rt.status
, rt.percentavailability
, rt.screenshot
, rt.rawhtml
, rt.recordcount
, rt.archive
--, rt.errormessage
from orion.seum.responsetime rt
where rt.transactionid=50
and rt.archive=0
and rt.status not in (1)
