Description

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)
