Branch Type

• Branch to Function Returning a Page:  With this branch type, a PL/SQL function is written that returns a numeric page id to branch to.

Example: 

declare
   n_page_id integer;
begin
   select 2205 into n_page_id from dual;
   return n_page_id;
end;

• Branch to Function Returning a Page:  With this branch type, a PL/SQL function is written that returns a numeric page id to branch to.

Example:

declare
   s_url varchar2(200);
begin
   select ' http://www.rampant-books.com'
   into   s_url from dual;
   return s_url;
end;

• Branch to PL/SQL Procedure:  This branch type is very uncommon, but available. A procedure can be written that will do the branching using this branch type.

 Example:

 owa_util.redirect_url( 'http://www.google.com' );

• Branch to Page:  It does just what it says.

• Branch to Page Identified by Item (Use Item Name):  This branch will use the value of another page item to determine the application page id to branch to.  This can be used if the user is provided with a select list of areas for them to branch to, such as Employee Management, Payroll, Billing, etc.

• Branch to Page or URL:  This is the default branch type presented when creating a branch and is the most common.  Using this type, it is possible to set many of the properties available in the other branch types.  The reason it is the most common is because the page to branch to can be set, along with the page items to set, and with which values to set them.  It is also possible to set the pages for which to clear the session state at the same time.  This branch type allows this to be set in the create branch wizard.  Even though it is manually possible to go back and edit the branch later to set these properties, it is convenient to do it in the wizard.

• Branch to URL Identified by Item (Use Item Name):  This branch will use the value of another page item to determine the URL to branch to.  This can be used if the user is provided with a select list of web sites for them to branch to, such as Google, Amazon, CNN, etc.
