Oracle Database Tips by Donald Burleson

Add Rows to a Tabular Form Process in APEX

The Add Rows to a Tabular Form process is used to go to the end of the records set for the Tabular Form and open a new row for editing.  There is no Multi Row Insert process because the MRU also takes care of the Inserts.

Adding a Column to a Tabular Form

This section will show how to add another column to the tabular form so it can also participate in the Multi Row processes for updating to the database.

1.       To start, modify the Select statement that populates the Tabular Form.  Navigate to the Page Definition screen and click on the Conference Attendees link to edit the Region Definition.

2.       On the Region Definition page, modify the region source and add the COMPANY column.  The Select statement should then look something like this:

select
"ID",
"LAST_NAME",
"FIRST_NAME",
"EMAIL",
"PHONE",
"COMPANY",
"RSVP_DATE",
"DONATION",
"PAYMENT"
from "#OWNER#"."CONFERENCE_RSVP"

3.       After modifying the region source, click the Apply Changes button.

At this point, it would be useful to run the page.  The Company column is now there, but it is not editable.  The next step is to make the column editable and to configure it to participate in the Multi Row processes.

4.       Click on the Edit Page 1081 link in the developer toolbar to get back to the Page Definition screen.

5.       Click on the Report link for the Conference Attendees region.  This will navigate to the Report Attributes page.

6.       On the Report Attributes page, click on the edit icon next to the COMPANY column.

7.       On the Column Attributes page, scroll down to the Tabular Form Element section and make the following changes.  The completed changes are shown in Figure 8.15.

§         Display As: Text Field.

§         Reference Table Owner: EASYHDB.

§         Reference Table Name: CONFERENCE_RSVP.

This must be the same as the table name in the MRD and MRU processes.

§         Reference Column Name: COMPANY.

§         Click Apply Changes.

Run the page to see the changes to the Tabular Form.  New developers are encouraged to make some data changes and try out the various functions on the page. 

The preceding sections have shown how to create a tabular form, how to add a column to a tabular form, how to make it editable, and have it participate in the Multi Row processes.  It also showed what the role of a Multi Row processes is in a Tabular Form.
