> Key: CAY-2365
> URL: https://issues.apache.org/jira/browse/CAY-2365
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 4.0.B2, 4.1.M1
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Minor
> Fix For: 4.0.B3, 4.1.M1
>
>
> If {{SQLExec}} query returns result set it fails as Cayenne tries to convert
> it into persistent objects, but there are no {{ClassDescriptor}} (even if
> there is this is not intended behavior).
> One example of such query can be MySQL {{OPTIMIZE TABLE}} clause, that
> returns operation result.
> But simple select can be used to test this:
> {code}
> QueryResult result = SQLExec.query("SELECT * FROM ARTIST").execute(context);
> {code}
