Once again you can update rows easily by using the Data tab interface.As you did in the previous exercise, click on a table in the Connections Navigator. Notice by clicking on a table different from the previous one worked on, the tab is replaced with the new selected table.To keep the EMPLOYEES tab and the DEPARTMENTS tab open, click the Freeze View pin before selecting the new object.If you always want new tabs to open, you can set a preference to pin tabs.
