Sorry,
When writing a query, right click on any table in the database explorer panel. You will see the context menu shown in the attachment. The top item allows you to insert a choice of statements into a query you are working on. That’s where I’d also like an option to get the same choice of statements, but just put onto the clipboard (preferably even if I’m not writing a query).
Interestingly, in the query designer window, right clicking on the generated sql gives options to both copy to clipboard and copy to new query tab, that’s the sort of behaviour I’m, looking for but available when right clicking on a table in the explorer.
