Onquoted primary key in IncrementGenerator ------------------------------------------ Key: HHH-909 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-909 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.0.5 Reporter: Andrey Grebnev Priority: Minor Fix For: 3.1 rc 1 Original Estimate: 10m Remaining Estimate: 10m I have examined the source code of Hibernate 3.0.5 and I found following problem. In org.hibernate.id.IncrementGenerator we can see the following code if (column==null) column = params.getProperty(PersistentIdentifierGenerator.PK); ... sql = "select max(" + column + ") from " + buf.toString(); and in org.hibernate.mapping.SimpleValue params.setProperty( PersistentIdentifierGenerator.PK, ( (Column) getColumnIterator().next() ).getName() ); getName() of org.hibernate.mapping.Column returns unquoted string. It is very bad because different DBMSes interpret unquoted field names in different manner. E.g. PostgreSQL converts all field names into lowercase and HSQLDB converts all field names into uppercase. As result the application built on Hibernate with IncrementGenerator is not portable. I offer to change params.setProperty( PersistentIdentifierGenerator.PK, ( (Column) getColumnIterator().next() ).getName() ); to params.setProperty( PersistentIdentifierGenerator.PK, ( (Column) getColumnIterator().next() ).getQuotedName(dialect) ); Andrey Grebnev
