[Hibernate-issues] [Hibernate-JIRA] Created: (ANN-369) @CollectionOfElements on a Map uses reserved word "key" as column name

[Martin (JIRA) <no...@at...>]

@CollectionOfElements on a Map uses reserved word "key" as column name
----------------------------------------------------------------------

         Key: ANN-369
         URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-369
     Project: Hibernate Annotations
        Type: Bug

  Components: binder  
    Versions: 3.2.0.cr1    
 Environment: Hibernate 3.2.0cr1, MySQL 5
    Reporter: Martin


This annotation
[User.java]
@CollectionOfElements
public Map<String, String> getMisc()

results in this create table statement:

create table User_misc (User_id bigint not null, element varchar(255), key varchar(255), primary key (User_id, key)) type=InnoDB

But "KEY" is a reserved word, so MySQL won't create that table. The default column name should either change or be enclosed by backticks.

    Attachment: dont_use_key_for_maps.diff

Patch for Annotations which changes "key" to "mapkey". This bug causes problems with MySQL and SQLServer

Seems not to be clear to everyone, but you can set the column name through
@org.hibernate.annotations.MapKey
