>                 Key: CAY-1957
>                 URL: https://issues.apache.org/jira/browse/CAY-1957
>             Project: Cayenne
>          Issue Type: Bug
>            Reporter: Graham Collinson
>            Priority: Minor
>
> If I were to write in sql
> Select * from test where a in (1,2,3) and a in (1,2)
>  
> I’d only get rows where a is 1 or 2.
>  
> If you do similar with cayenne expressions
>  
> Expression exp = ExpressionFactory.inExp(COLUMN_A, {set with 1,2,3})
> .andExp(ExpressionFactory.inExp(COLUMN_A, {set with 1,2});
>  
> Then cayenne will turn that into a sql statement like
> Select * from test where a in (1,2,3);
> Is this expected behaviour?
> To work more like SQL it would be better if there were 2 in statements or if it could
be optimised to be in (1,2)
