Query Definitions Differ Dialog Box (Visual Database Tools)
This dialog box notifies you that your query cannot be represented graphically in the Diagram and Criteria panes, and that you can edit your query only in the SQL pane.
This dialog box may appear when you enter or edit an SQL statement in the SQL pane; you then move to another pane, verify the query, or attempt to execute the query; and one of the following conditions applies:
The SQL statement is incomplete or contains one or more syntax errors.
The SQL statement is valid but is not supported in the graphical panes (for example, a Union query).
The SQL statement is valid but contains syntax specific to the data connection you are using.
The dialog box displays a message with the reason that the SQL statement cannot be represented, and then asks how you want to proceed.
Choose this button to specify that you want to accept the SQL statement, either to edit it further or to execute it. If you accept the statement, the Diagram and Criteria panes appear dimmed to indicate that they do not represent the statement in the SQL pane.
Choose this button to discard your changes to the SQL pane.
