             Summary:  joining 2 procedures results in QueryPlannerException: TEIID30275 Join region with unsatisfied access patterns cannot be satisfied by the join criteria
                 Key: TEIID-4823
                 URL: https://issues.jboss.org/browse/TEIID-4823
             Project: Teiid
          Issue Type: Bug
    Affects Versions: 9.1.4
            Reporter: Bram Gadeyne
            Assignee: Steven Hawkins


I have a query like this where I join a regular table with a virtual procedure.
 
{code:sql}
select gd.patientid, ip.production  
from prod_P_GeneralData gd  
join pr_patient_in_production ip on ip.patientid = gd.patientid  
where gd.status = 1;  
{code}
 
This works fine and returns 58 rows with no null values. The pr_patient_in_production procedure has 1 input parameter called patientid (integer) and one output parameter called production (boolean)
 
Adding a second procedure call results in an excepion:
 
{code:sql}
select gd.patientid, lrs.datetime, lrs.varvalue as phtype  
from prod_P_GeneralData gd  
join pr_patient_in_production ip on ip.patientid = gd.patientid  
join pr_retrieve_labres lrs on  
  lrs.patientid_in = gd.patientid  
  and lrs.production = ip.production  
  and lrs.resultgroup_in  = 'pH-type'  
  and lrs.varvalue = 1  
where gd.status = 1  
order by lrs.datetime, lrs.entertime desc  
{code}
 
This pr_retrieve_labres procedure has patientid_in (integer), production (boolean) and resultgroup_in(string) as input parameters and also some output parameters.
 
The exception is: Error: TEIID30275 Remote org.teiid.api.exception.query.QueryPlannerException: TEIID30275 Join region with unsatisfied access patterns cannot be satisfied by the join criteria, Access patterns: [[Access Pattern: Unsatisfied [ip.patientid] History [[ip.patientid]]], [Access Pattern: Unsatisfied [lrs.production, lrs.patientid_in] History [[lrs.patientid_in, lrs.production, lrs.resultgroup_in]]]]
