3.3.4. Setting View Object Control Hints You can specify Control Hints for an attribute in a View Object. See the screenshot below. JHeadstart might use some of these properties in the same way as Control Hints specified for an Entity Object. See section Setting Entity Object Attribute Properties used by JHeadstart fore more information. 3.3.5. Determining the Order of Displayed Rows In most situations you want to order the queried records. To accomplish this you must add an Order By clause to each View Object. Attention: In general, there is NO DEFAULT sort order you can rely on. 1. Select the View Object, right mouse click, select Edit to open its Properties dialog. 2. Go to the Query node and enter the Order By clause. You can press the Edit button to select available attributes. Often, the view is ordered by the Descriptor attribute. It may also be ordered by a lookup attribute. 3. Be sure to use the 'Test' button to verify the query. 3 - 18 Creating Business Components JHeadstart Developer's Guide
It is also possible to let the user order the records as desired in a page with table format. See chapter 5, section “Allowing the user to sort data in a table page” for more detail on how to do this. 3.3.6. Creating Calculated or Transient Attributes Sometimes you want to show an attribute that does not exist in the correct form in the database. For example: you want a read-only attribute FULL_NAME based on the FIRST_NAME and LAST_NAME attributes. In such cases, you need to add a calculated or transient attribute. Note the important difference between a calculated and a transient attribute: • A calculated attribute is present in the SQL query: the calculation is done by SQL at retrieval time. So a calculated attribute is only recalculated when the query is re-executed. Imagine a calculated attribute FullName that is a concatenation of FirstName and LastName. When the FirstName is changed in the application, the data needs to be requeried to refresh FullName. Only use a calculated attribute for read-only fields. • A transient attribute is not present in de SQL query. You have to calculate the value in a get method in the View Object. Every time the transient attribute value is needed, the get method is called and the transient value is recalculated. So you have no synchronization issues when using a transient attribute. The only drawback of a transient attribute is that you have to code a get method in the ViewRowImpl class. Reference: See also the Oracle Application Developer Framework Developer’s Guide for Forms/4GL Developers Release 10.1.3, section 7.6: Adding Calculated and Transient Attributes to an Entity-Based View Object. 3.3.6.1. Steps to create a calculated attribute 1. Select the View Object, right mouse click, select Edit to open its Properties dialog. 2. Go to the Attributes node and click on 'New'. 3. Enter an appropriate name for the attribute. 4. Check ‘Mapped to Column or SQL’. 5. Give the attribute an alias. 6. In the Expression text area, key in the SQL expression to create the concatenated string. Note that if you have included lookup attributes in your view definition, then you must include the alias you have given to the selected entity objects in the SQL Expression: For example: LAST_NAME || ', ' || FIRST_NAME JHeadstart Developer's Guide Creating ADF Business Components 3 - 19
