The Credit_Rating item in the Customers block of an Order Entry form must be restricted to three possible values: Good, Poor, or Null (the latter value indicates that the credit rating has not been determined). Order entry clerks must be able to update this item to any of the preceding three values. You want to change the item to a check box labeled "Credit Risk" that should be selected if the customer has poor credit, the check box should not be selected if the customer's credit rating is good or undetermined.

When tabbing through items in the Employees form, users should not be able to navigate to the Salary text item. If they need to update the item, they will have to explicitly navigate to it by using the mouse. Which property setting accomplishes this requirement?

The Orders form has four blocks. The Orders and Order_items block are on the CV_Order content canvas; the inventories block items are on the CV_inventories content canvas; and Control block buttons are on the CV_Buttons toolbar canvas. All buttons have mouse Navigate set to No. The Order_Items block is a detail of Orders. The inventories block is a detail of Order_Items, showing the stock of the selected product. There is a button in the Control block with a When-Button-Pressed trigger: IF GET_CANVAS_PROPERTY(:SYSTEM.cursor_item, item_canvas) = 'CV_ORDER' THEN GO_BLOCK ('inventories') ELSE GO_BLOCK('orders'); END IF; When you run the form and click the button, navigation does not occur, and the form displays the runtime error “FRM-41053: Cannot find Canvas: invalid ID.” What should you do to correct this problem?

Which four types of variables must have their names preceded by a colon when they are referenced in trigger code?

The Order Entry application contains several forms. The inventories form uses an LOV that is based on a record group that queries the Warehouses table to return a warehouse ID. Several of the forms use LOVs that are based on the same query. You decide to centralize the creation of the record group to the entry form of the application, which opens all the other forms, for example, to open the inventories form, there is a When-Button Pressed trigger on the inventories button with the following code; OPEN _FORM ('inventories'); in a When-New-Form-instance trigger for the entry form, you create the warehouse_rg record group by using the CREATE_GROUP_QUERY built in with the following arguments: ('warehouse_rg' , 'SELECT ALL WAREHOUSE.WAREHOUSE_ID, WAREHOUSE.WAREHOUSE_NAME FORM WAREHOUSE order by warehouse_name); You also populate the record group in this trigger. What must you do to make this record group available to the inventories form and the other forms?

Iin the Human Resources form shown in the Exhibit, you want to modify the prompts, heights, and widths of the Department Id, Manager Id, and Location Id Holds in the Departments data block. What must you select before invoking the Layout Wizard in reentrant mode to modify these item properties?

You are implementing a JavaBean in a form, the bean has no visible component on the form when invoked, the bean displays an input text where users enter a zip code, the bean has a single method that returns a short weather forecast for that zip code as a character value. How can you retrieve that value so that you can display it to the user?

The Orders database table uses Order_id as its primary key. You have written the following code to use in the Orders block of a form: SELECT orders_seq.NEXTVAL INTO :orders.order_id FROM SYS.dual; Which statement is true about this code?

You want to display employee records in tabular format, but the form is not wide enough to display all the items in the Employees block. The employee IDs and names of displayed records should always be visible, but you want to scroll the additional information as users tab through the Items, the form should look like a spreadsheet with the first two columns frozen. Which canvas types would be most appropriate in this scenario?

You have created a complex menu structure with several types of menu objects. To which objects would you assign menu commands?

View the Exhibit. The Departments table in the database contains four columns. In a new form, you use the Data Block Wizard to add all columns to the block, but in the layout Wizard, you choose all columns except Location_Id to add to the canvas. The Object Navigator and layout Editor appear as shown in the Exhibit. You then decide that you do need to display Location_Id on the canvas. What object must you select before invoking the Layout Editor in re-entrant mode to make this change?

To avoid overloading the database during busy times, you decide to restrict the queries that are executed on the Orders form so that users query by either Order ID or Customer ID during these times. Which trigger is most appropriate for the code to enforce this restriction?

You have created an editor named MyEditor, and you want it to be available to edit the text item Product_Description. You can associate the editor with the text item by setting the Editor property of Product_Description to MyEditor.

The Orders form is sometimes run automatically and sometimes run from the Customers form, when it is run from the Customers form, any queries should be restricted to the customer that is currently selected. The Customers form button that runs the Orders form sets a global variable to the current customer ID. The Orders form has a button labeled Execute Query with the following When-Button Pressed trigger: DEFAULT_VALUE (NULL, 'GLOBAL.Customer_id'); IF: GLOBAL.customer_id IS NOT NULL THEN SET_BLOCK_PROPERTY ('orders', DEFAULT_WHERE, 'orders.customer_id = ' | | :GLOBAL.CUSTOMER_id); END IF; EXECUTE_QUERY You want to duplicate that functionality in a menu item for the Summit menu that is attached To the Orders form. What changes must you make to the code so that the menu code functions as it does in the form?

You are planning the alerts that are needed for your Human Resources application. You wish to display the following in alerts: * A message to inform the user about being at the just record * A warning about a potential conflict with the data just entered * A message to display a validation error to the user * A warning that the salary is out of range and that asks whether the user wants to correct it You want the note symbol ( ) to appear on alerts that display only informative messages, the warning symbol to appear on messages where you will allow the user to continue despite some data problem, and the alarm boll symbol to appear where the user will not be allowed to continue without correcting the situation that caused the alert to be displayed. You want to define the minimum number of alerts possible and customize them at run time. Which alerts should you define

You have installed WebLogic and Forms with a default configuration, which has been tested and determined to be correct. After creating a basic form in the Forms Builder, you click Run Form to test it. Forms Builder displays an error dialog box with the following message: FRM-10142: The HTTP Listener is not running on <host> at port 9001. Please start the listener or check your runtime preferences.

Which statement is always true about using OPEN_FORM to open multiple forms in an application?

You put some code in a Post_Update trigger and raise the FORM_TRIGGER_FAILURE under certain conditions. Does a rollback take place if the trigger falls?

View the Exhibit. You have placed the following code in a Post insert trigger on the Orders block: SELECT orders_seq.NEXTVAL INTO :orders.order_id FORM SYS.dual; You have also set Item properties for the Order_Id Item in the form so that users cannot directly enter an Order ID. As the SUMMIT user, you run the form to test it. Yon are able to insert a record in the block, but when you click Save, you have a database error as shown in the Exhibit.

Yon have created a list item for the Credit__Rating field in the Customers form, the Finance department usually determines a range of scores that pertain to the customer, the values in the list are Excellent, Good, Fair, and Poor, corresponding to the ranges provided by Finance. The default value Fair, because that is the range that applies to most customers. Sometimes, Finance can provide an exact credit score; so users must be able to enter the exact numerical value if it is known. Often clerks enter the customer data before the performance of a credit check, so they must be able to enter a blank value if the credit rating is not yet determined. Users want to be able to select a blank value from the list, but the list does not display a blank line for them to select. How can you meet this requirement without changing the default value of the list item?
