> Constant join fails
> -------------------
>
> Key: OPENJPA-2054
> URL: https://issues.apache.org/jira/browse/OPENJPA-2054
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.1.0
> Reporter: Michael Spiro
> Labels: Constant, join
>
> According to the documentation (Part 3, chapter 7, paragraph 6), join
> criteria can be defined so that a column in the source or target table must
> have some constant value. The constant value should be specified in the
> attribute "referencedColumnName" of the @JoinColumn annotation. If the
> constant is a string then its value should be enclosed first in single quotes
> and then in double quotes like this:
> @JoinColumn(name="table.column", referencedColumnName="'value'")
> A numeric constant value needs just a single pair of double quotes:
> @JoinColumn(name="table.column", referencedColumnName="2")
> However a practical test shows that both options produce an error.
