Visual Database Tools
Unsaved Changes Exist Dialog Box
Appears if you close the last table of a database diagram or the diagram itself in the Database Designer when there are unsaved tables in memory.
Note Although you cannot undo changes made to a table or database diagram, the changes are not saved to the database until you save the table or diagram. You can discard any unsaved changes by choosing No and closing all open diagrams without saving them.
Yes
Saves all the tables shown in the list.
No
Closes the diagram without saving the changes.
Save Text File
Displays the Save As dialog box, letting you specify a location for a text file containing a record of the tables that were affected by the changes you made.
