Re: Dual homes on application clients

YMMV but in my experience 9i client works happily against a 10g
database ( and vice versa). We've got a mixture of 9i and 10g and for
tns connections (via SQL*Plus


With old SQL*Plus version and new db you can get some suprises because
SQL*Plus also parses commands, for example:

Table dropped.

SQL> flashback table t to before drop;
SP2-0734: unknown command beginning "flashback ..." - rest of line ignored.

Although one can of course fool it:

SQL> begin
 2    execute immediate 'flashback table t to before drop';
 3  end;
 4  /

PL/SQL procedure successfully completed.

Probably not very common problem though :)
