I need to retrieve quite a bit of data from our oracle DB and to do so I need to run 20+ queries. Is there any way to run more than one query at a time on the same connectio
In SqlDeveloper preferences: Tools > Preferences > Database > Worksheet check the option for New Worksheet to use unshared connction. This will allow you to execute multiple queries at the same time, each in each tab. See a screenshot too.
