[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1657?page=c... ] Sebastian Anzani commented on HHH-1657: --------------------------------------- Hello, i have found the same problem trying to delete a hierarchy having a composite primary key, the HQL statement that I am trying to execute is the following delete from Employee _emp where concat(_emp.lastName,'_$$_',_emp.firstName) in(:values) in my case case "Employee" extends "Person" and the SQL query generated to fill the temporary table used for bulk delete is the following: insert into HT_employee select employee0_.`LASTNAME` as `LASTNAME`, employee0_.`FIRSTNAME` as `FIRSTNAME` from `employee` employee0_ inner join `person` employee0_1_ on employee0_.`LASTNAME`=employee0_1_.`LASTNAME` and employee0_.`FIRSTNAME`=employee0_1_.`FIRSTNAME` where concat(`LASTNAME`, '_$$_', `FIRSTNAME`) in ( ? ) Obviously the problem is caused by the missing of the correct entity alias into the concat function of the where clause. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
