Jean-Francois Lagace commented on HHH-2098:
-------------------------------------------

I was able to reproduce the same problem using the same mapping files that Phil (the reporter of this problem) included in his description.  But the problem is not that the temporary table is not created.  Following are the statements that Hibernate execute before to delete.

---------------------------------------------------------------------------------
create global temporary table HT_PATIENT_SCAN_CD_VW 
(
        PATIENT_SCAN_CD_GUID raw(255) not null, 
        OPERATING_CNTX_GUID raw(255) not null
) 
on commit delete rows

---------------------------------------------------------------------------------
insert into HT_PATIENT_SCAN_CD_VW 
select patientsca0_.PATIENT_SCAN_CD_GUID as PATIENT_SCAN_CD_GUID, 
        patientsca0_.OPERATING_CNTX_GUID as OPERATING_CNTX_GUID 
from CDM_PAT_1_0.PATIENT_SCAN_CD_VW patientsca0_, 
        CDM_FND_1_0.SCAN_CD_VW patientsca0_1_ 
where patientsca0_.PATIENT_SCAN_CD_GUID=patientsca0_1_.SCAN_CD_GUID 
        and patientsca0_.OPERATING_CNTX_GUID=patientsca0_1_.OPERATING_CNTX_GUID 
        and PATIENT_SCAN_CD_GUID=? 
        and OPERATING_CNTX_GUID=?


The problem is that in the second statement, in the last 2 lines of the where clause, the table name is not specified with the column name.  And in this case, the column OPERATING_CNTX_GUID exists in both tables.  That is the source of the error "ORA-00918: column ambiguously defined".

> Hi, I'm using Hibernate 3.2.0 CR3 (also tried it with 3.2.0CR4) and when I try to delete entities in batch (with an HQL query), I got an error in the SQL translation of my query. I try to delete an entity that is the child of another one. Here are my mapping files:

> There are 2 delete statements since it has to delete both the child and the parent. In the from clause in the select statement, the table called HT_PATIENT_SCAN_CD_VW is used, but it doesn't exist in our model.  I suppose it should be a temporary table created by hibernate to keep in memory which rows have to be deleted when it's time to delete the parent table.  The problem is that this table doesn't seem to be created properly before running delete statements cause I get the following exception when it is called on the database:
