Richard Zowalla resolved OPENJPA-101.
-------------------------------------
Resolution: Fixed
Already fixed on master: JPQL.jjt:691-699 constructor_parameter accepts
scalar_expression, which includes string_literal, numeric_literal and
input_parameter (string_primary at 1251, arithmetic_factor at 1071,
arithmetic_primary at 1080). Closing; please reopen if this still happens with
OpenJPA 4.x.
> enhance JPQL Constructor Expressions implementation

> Key: OPENJPA-101
> URL: https://issues.apache.org/jira/browse/OPENJPA-101
> Project: OpenJPA
> Issue Type: Improvement
> Components: query
> Reporter: wanyna
> Priority: Major
>
> There are two tables A and B, I need to execute sql like
> "insert into A select ... from B".
> I use JPQL Constructor Expressions,
> select new A(...) from B, got A list then persist.
> But some fields of A depends on program context, not direct from B, so SELECT
> NEW clause should look like these :
> select new A(B.column1, 'xxx') from B, or
> select new A(null, B.column2) from B, or
> select new A(variable, B.column2) from B.
> Unfortunately, OpenJPA doesn't support this.
> I have to get the result object[] list and constuct A in my code now.
> If JPQL Constructor Expressions become more powerful, my code will be more
> simple then.
