Jeremy Bauer commented on OPENJPA-1540:
---------------------------------------
Problem 1. There looks to be a bug in the code that determines whether a value
needs to be delimited based upon DBMD returned by the JDBC driver. I am
working on a fix.
Problem 2. If a value requires delimiters (ex. "foo bar") the code generator
needs to escape each delimiter. Ex: @Column(name="\"foo bar\"").

> Key: OPENJPA-1540
> URL: https://issues.apache.org/jira/browse/OPENJPA-1540
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.0.0-beta
> Reporter: Laird Nelson
> Assignee: Jeremy Bauer
>
> During a reverse mapping run, it's often common to take the output of a
> SchemaGenerator and feed it to an XMLSchemaSerializer via its addAll() method.
> When the DBDictionary that was in effect at schema generation time is one
> that supports delimiters (see InformixDictionary), then the identifiers on
> all the artifacts in the SchemaGroup housed by the SchemaGenerator have
> quotes in them.
> Consequently, when the XMLSchemaSerializer writes its schemas to disk, you
> can get strange results. Here's an example <column> fragment:
> <column name=""foobar"">
> Technically I suppose this may not be a bug in XMLSchemaSerializer, since it
> is simply serializing what it is handed. But given that other tools consume
> its XML schema files, and given that the value of name attribute will be read
> in as a String, and given that usually what happens is that a String is
> turned into a DBIdentifier and delimited/quoted as necessary, I am not sure
> that delimiters should be stored by the XMLSchemaSerializer.
> A downstream effect of this bug is that any reverse mapping that takes place
> from here involving annotations will not compile. That is, if you ask the
> ReverseMappingTool for example to produce annotated Java objects, the
> annotations will look like this:
> @Column(name=""foobar"")
> ...which will not compile.
