I have a class and subclass mapped in hibernate as a a joined sub-class. I perform a batch delete to remove all the instances of the subclass eg "Delete from SpecialProduct".
The way this seems to work is it creates a temporay table and uses that to delete from each table.
This works fine on HSQL but when i run the exact same on sybase (ASE 12.5) it fails, from what i can see it is trying to insert into the temporary table (in this case #SpecialProduct) before it is created. It either should create the temp table first or use syntax such (select x,y into #TempTable from A) and cerate the temp table in line. Any advice of if this is a bug and where I might start looking in the code to help resolve.
thanks
Andy
