Patrick Linskey updated OPENJPA-75:
-----------------------------------
Fix Version/s: 0.9.7
> error message for missing query id var needs improvement
> --------------------------------------------------------
>
> Key: OPENJPA-75
> URL: https://issues.apache.org/jira/browse/OPENJPA-75
> Project: OpenJPA
> Issue Type: Bug
> Components: query
> Reporter: David Wisneski
> Fix For: 0.9.7
>
>
> the query is
> select sum(loginCount), sum(logoutCount) from AccountEntity as a where
> a.accountProfile.userID like 'uid:%'
> loginCount and logoutCount are declared in a MappedSuperClass.
> the correct query is
> select sum(a.loginCount), sum(a.logoutCount) from AccountEntity as a where
> a.accountProfile.userID like 'uid:%'
> Rather than a syntax error, a ArgumentException was thrown. (see below)
> Also the user would like to see a better error message in the case of a field
> name using wrong upper/lower case.
> In other words, if the query was
> where a.userid = ...
> and what he intended was
> where a.userId = ...
> then the message should say " userid undefined. DId you mean userId? "
> Also if a state field is inherited but declared private and hence not
> visible, then error message should read
> "a.userId invalid because it is not visible" rather than "a.userId not
> defined".
