Hello Sergei,

I have one problem my where optimization works for query like

select * from t1 where abc=1;

but in query like

select * from t1 where abc=(select xyz from t2 where xyz=1);

does not work because in these query the charset is different from what used in

t1 for inserting data and hence generation different hash for same data

how i solve this problem.

Regards

sachin
