[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-1000) Problem with PostgreSQL using uppercase letters in tables

[Jeff Adama (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HBX-1000?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38004#action_38004 ] 

Jeff Adama commented on HBX-1000:
---------------------------------

There is an additional issue where the backticks workaround does - not - work. This happens when working with mixed case PostgreSQL sequences associated with auto numbering ids and a sequence generator in the code (JBOSS Seam in my case). The - only - way that I was able to make this work was by changing all sequence names in the PostgreSQL database to lowercase.
Consider the following JBOSS Seam entity code:

   @Id
   @NotNull
   
   //The following version does - NOT - work: (where the sequence name in PostgreSQL is mixed case)
   @SequenceGenerator(name="discountRate_autoGenerationDefault_seqIdentifier", sequenceName="discountRate_autoGenerationDefault_seq", allocationSize=1)
   
   //The following version - DOES - work: (where the sequence name in PostgreSQL is all lowercase)
   @SequenceGenerator(name="discountRate_autoGenerationDefault_seqIdentifier", sequenceName="discountrate_autogenerationdefault_seq", allocationSize=1)
   
   @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="discountRate_autoGenerationDefault_seqIdentifier")
   @Column(name="`autoGenerationDefault`", unique=true, columnDefinition="bigserial")
   public Long getId()
   
For developers working with hibernate and PostgreSQL, these issues are significant.

Jeff

>             Project: Hibernate Tools
>          Issue Type: Bug
>          Components: reverse-engineer
>    Affects Versions: 3.2.beta11
>         Environment: Hibernate 3.2.5.ga, Hibernate Tools 3.2.0 beta9a, PostgreSql 8.2, postgresql-8.2-506.jdbc3.jar, Eclipse 3.3.0, all running on Windows XP at the moment (including PostgreSql)

> I have problems using Hibernate tools when using upper case letters in a PostgreSQL database.
> I can configure Hibernate Tools for my local PostgreSql installation without any problems. I can access the table structure in the view Hibernate Configurations and do reverse engineering by creating XML mappings and beans. No problem.
> But when I'm using upper case characters in table names Hibernate Tools can't access the table structures any more. Hibernate Configuration shows the tables, but when I want to see the columns, it doesn't show anything. Reverse engineering also doesn't work any more.
> So, the following works:
> TABLE cms_clusterMessage
> pk_clustermessageid
> fk_clusternodeid
> messagetype
> messagedetail
> The following doesn't work:
> TABLE cms_clusterMessage
> PK_ClusterMessageId
> FK_ClusterNodeId
> MessageType
> MessageDetail
> I tried to use different JDBC drivers because I thought it could be a bug of the driver. But it wasn't.
