SQL Developer provides a history function that allows users to see previous queries that were executed and reuse or edit them, as required. In this video, learn how to access the history function of SQL Developer and view your past queries.
- [Instructor] SQL Developer also keeps track…of your recently executed SQL commands.…You can access this log of recently executed queries…by pressing on the small SQL History button.…You will be presented with a grid…at the bottom part of your screen…showing you all of your recent SQL commands…that have executed.…Note that the list you see on my screen…and the list you will see in your environment…will most probably be different, so don't worry about it.…You can also choose to filter or search…for individual SQL commands based on a string value.…
So for example, I can search for all SQL commands…which have been executed and…included the Employees table.…Alternatively, I can search for SQL commands…which have accessed the Departments table.…You can close the SQL History pane…by pressing on the small X icon.…
