Andrey Razumovsky updated CAY-1105:
-----------------------------------
Attachment: patch-test-Expr.txt
> Expressions in-memory automatic type convertion
> -----------------------------------------------
>
> Key: CAY-1105
> URL: https://issues.apache.org/cayenne/browse/CAY-1105
> Project: Cayenne
> Issue Type: Improvement
> Components: Cayenne Core Library
> Affects Versions: 3.0
> Reporter: Andrey Razumovsky
> Assignee: Andrus Adamchik
> Attachments: patch-test-Expr.txt

>
> The root of the problem is difference in behavior of expressions on server
> (using queries) and in-memory (using Expression.match(...). All DBMS I know
> support automatic type convertion, i.e. if I write
> SELECT * FROM a WHERE intProperty='1'
> everything will go OK.
> So, if I write an expression like [note quotes at 1!]
> ExpressionFactory.greaterExp("intProperty", "1")
> it will go normally with a query, but will result in an exception if I try to
> invoke match(...).
> I suggest to make the behavior similiar and therefore implement automatic
> type convertion on expressions. I've submitted a patch with a number of
> tests, which all fail. I think the must all succeed.
> Comments and other expression improvement suggestions are welcomed
