> Sybase SQL syntax requires that all derived tables have a correlation name. The DBDictionary
default for requiresAliasForSubselect is false. Overriding it to true in the Sybase dictionary
class fixes the problem OOTB else users have to override it in the configuration by default
with Sybase.

>                 + '&& complexEmbedded.ownerField.id1 == 3 '
>                 + '&& complexEmbedded.stringSet.contains (\'foo\') '
>                 + '&& complexEmbedded.embedded != null '
>                 // just to test not null
>                 +
