Export result set on Dbeaver to CSV

You don't need to use the clipboard, you can export directly the whole resultset (not just what you see) to a file :

1. Execute your query
2. Right click any anywhere in the results
3. click "Export resultset..." to open the export wizard
4. Choose the format you want (CSV according to your question)
5. Review the settings in the next panes when clicking "Next".
6. Set the folder where the file will be created, and "Finish"

The export runs in the background, a popup will appear when it's done.

In newer versions of DBeaver you can just :

1. right click the SQL of the query you want to export
2. Execute > Export from query
3. Choose the format you want (CSV according to your question)
4. Review the settings in the next panes when clicking "Next".
5. Set the folder where the file will be created, and "Finish"

The export runs in the background, a popup will appear when it's done.

Compared to the previous way of doing exports, this saves you step 1 (executing the query) which can be handy with time/resource intensive queries.

The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.
