Confusion with a query

simkaur,


Have a left join with patient acoount - so irrespective of whether matching rows exist in patient_account or not, the rest of the setup wont be affected :)


something like:



select p.col_name1,m.col_name2
from patient p
inner join message m on p.patient_GUID=m.patient_GUID
left join patientaccount pa on p.patient_GUID=pa.patient_GUID





Thanks,

Jay
