Ivan Chan commented on TEIID-2219:
----------------------------------
Actually, I am still able to reproduce this problem. I can provide you my vdb if you can show me how to export VDB from VDBRepository.
Here is my sql statements:
I was running 2 sql statements one right after the other. And I got exception in the 2nd SQL statement.
1st SQL:
select count("FoodmartDataSource_public_department"."department_description") as "FoodmartDataSource_public_department_department_description_Count" from "FoodmartDataSource_public"."department" "FoodmartDataSource_public_department"
2nd SQL:
select count("FoodmartDataSource_public_department"."department_description") as "FoodmartDa
taSource_public_department_department_description_Count",
count("FoodmartDataSourceJNDI_public_employee"."gender") as "FoodmartDataSourceJNDI_public_employee_
gender_Count"
from "FoodmartDataSource_public"."department" "FoodmartDataSource_public_department"
inner join "FoodmartDataSourceJNDI_public"."employee" "FoodmartDataSourceJNDI_public_employee" on ("
FoodmartDataSource_public_department"."department_id" = "FoodmartDataSourceJNDI_public_employee"."de
partment_id")
Exception:
Caused by: com.jaspersoft.commons.dataset.DataSetException: Exception calling JRDataSource.next() fo

taSource_public_department_department_description_Count",
