 Post subject: Update statement created when deleting a collection.

Hello,

I am trying to delete a collection of a parent object and once I issue the delete and commit commands Hibernate throws a stack trace. I have looked into the issue and it appears that Hibernate is trying to execute an "UPDATE" statement with "nulls" in the key fields on the child within the collection. This is causing DB2 to complain about nulls in a non null field.
I have included the parent and child hbm files. I am sure I can solve this issue by doing a native SQLQuery, but I would like to use Hibernate functionality whenever possible. It is quite possible that I have a mapping issue, but I cannot see the problem.

Any help would be greatly appreciated!

The generated SQL (show_sql=true):

update HZAZDB3.OFNV7ID1 set CFFACLID=null, CMDORNUM=null, INTKDATE=null where CFFACLID=? and CMDORNUM=? and INTKDATE=?

Debug level Hibernate log excerpt:


Problems with Session and transaction handling?

No

Hello,

I have debugged the issue some more. I have found that the "OneToManyPersister" has a method called generateDeleteString(). See below

Shouldn't this method be creating a delete sql statement ?


/**
* Generate the SQL UPDATE that updates all the foreign keys to null
*/
protected String generateDeleteString() {

Update update = new Update( getDialect() )
.setTableName( qualifiedTableName )
.addColumns( keyColumnNames, "null" )
.setPrimaryKeyColumnNames( keyColumnNames );

if ( hasIndex && !indexContainsFormula ) update.addColumns( indexColumnNames, "null" );

if ( hasWhere ) update.setWhere( sqlWhereString );

if ( getFactory().getSettings().isCommentsEnabled() ) {
update.setComment( "delete one-to-many " + getRole() );
}

return update.toStatementString();
}

eh no, delete a one-to-many collection is done by updating the tables that points to it.

Hi Max,

The 3 fields that are trying to be updated are 3 primary keys from the child table.


I am trying to map a set of children to the parent. The 3 primary keys from the parent map to the first 3 primary keys of the child. There is a total of 5 primary keys for the children.

Have I configured my mappings incorrectly ?

Again, thanks for the help!

so this is not a collection you can delete; only read.

Hi Max,

I guess that would be true. It is read, create and update only seeing how Hibernate works with this collection.

Did I map the config files correctly ? Is there another solution ?

I am ready to implement a native sql statement to delete both the parent and children.
