Hello there,

When I execute the PLSQL block in SQL window which has DBMS output text, it wipes previous DBMS output and displays only the output of most recent execution.

Is there any setting where we can keep the old output retained and the new output is added at the end (even if the new output is displayed on top of previous output will do).

Thanks.

Yes, there is: Preferences/Oracle/Output => uncheck 'Clear before execute'
