Subject [jira] [Created] (OPENJPA-2054) Constant join fails
Date Fri, 30 Sep 2011 16:26:45 GMT
Constant join fails

                 Key: OPENJPA-2054
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 2.1.0
            Reporter: Michael Spiro

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.
