Resolution: Fixed
> Change mapping of char fields
> -----------------------------
>
> Key: JDO-110
> URL: http://issues.apache.org/jira/browse/JDO-110
> Project: JDO
> Type: Bug
> Components: tck20
> Reporter: Michael Watzek
> Assignee: Michael Watzek
> Fix For: JDO 2 beta
>
> The mapping of character fields in pc classes
> "PCPointSingleFieldPrimitiveChar", "PCPointSingleFieldCharacter",
> "FieldsOfCharacter", "AllTypes" needs to be changed from CHAR(1) to INTEGER.
> The rationale is that instances of those classes have character values which
> are initialized based on numerical values rather than character values, e.g.
> "Character.MAX_VALUE", "Character.MIN_VALUE", or
> "System.currentTimeMillis()%Character.MAX_VALUE".
> For this reason, we decided to adapt the ORM metadata rather than to adapt
> the schema: <field> elements corresponding to fields of type "char" or
> "java.lang.Character" will have "jdbc-type" attributes, e.g.
> <class name="PCPointSingleFieldPrimitivechar"
> table="PCPointSingleFieldChar">
> <field name="id" primary-key="true">
> <column name="ID" jdbc-type="INTEGER"/>
> </field>
> ...
> </class>
