We changed our database from 8i to 9i.

when we traced the client sql's it is adding a
double quotes with all columns, in the Current sql.

example

select emp."emp_name", emp."sal" from emp;

But when the same application when we run from 8i
the sql at the backend is

select emp.emp_name,emp.sal from emp;

Is there any performance issues? Is there any client side configurtion
change required to change the above..?

Thanks
