Hi,
I was debugging some speed issues against some meaty SQL I have, and it seems to come down to selecting from dual but only in a SQL window.
So, I did a quick test and found that doing it through PLSQL Dev's SQL window was very slow, whilst PLSQL Dev's command window, SQLPlus and Oracle SQL Developer was lightning.
Consider the following from SQLPlus.
SQL> select 1 from dual;
1
----------
1
Executed in 0.019 seconds
The same in SQL Window executes in around 0.5s consistently.
I've tried the same on other machines at my disposal and it seems consistent.
Is this a known issue or is it something to do with our setup?
Thanks
Matt.
