-------------------------------------

Hi Steven,

The user query was 

select loc.WardAbbr, inf.Patientid, inf.GivenAt, inf.MVGType, inf.pharmaid
from #medcontinf as inf
join MVGPatientLocations as loc on inf.patientid = loc.patientid and loc.datum = inf.GivenAt
join TV_Numbers as TV_1 ON TV_1.nr <= inf.aantal
join TV_Numbers as TV_2  ON TV_1.nr+TV_2.nr*10 <= inf.aantal

#medcontinf is an in memory table.
MVGPatientLocations is a foreign temporary table (located on a MySQL database server)
TV_Numbers is a view

This is the full stack trace:
