Noetix: Omitting View Templates (Script)

Similarly to a previous post to omit view columns from templates (see here) this script will allow you to omit whole view templates by calling a single file. Here is the script;

define noetix_view = &1;
define update_date = &2;

UPDATE N_View_Templates N
   SET N.USER_INCLUDE_FLAG = 'N',
       n.last_update_date = TO_DATE('&update_date'),
       n.last_updated_by = 'A Pellew'
 WHERE n.view_label = '&noetix_view'
;

COMMIT;

The script file (omit_view_template_xu2.sql - I've called it) takes two parameters the first if the view label to disable and the second is the date to set the Last_Update_Date to.

You can call this script from wnoetxu2.sql. For example;

@omit_view_template_xu2.sql INV_Transaction_Details 17-JUN-2012

The point of doing this was to make sure that, if the way a view is disabled changes, we only have to update a single file. Hope this helps!

Noetix: Extracting a View As A Script

UPDATE 16-DEC-2012: Added in the table n_view_col_property_templates. Where a view is using key flex fields the copying of the view was failing as the additional information (well, for Inventory anyway) was not being populated in this table.

The following script generates source code (i.e. uses DBMS_OUTPUT.PUT_LINE), you will need to copy/paste this into a separate file AND then change the name of the view before you run it (otherwise you will get a lot of duplicate errors).

Five fields are overwritten by this script; Last Updated By/Created By (replaced with the value in the variable at the top), Last Updated Date/Creation Date (set to today), and the product version set to 12+.

To add other tables you can just add calls to "ProcessTable" (rows 91-96) for the additional tables you want to include.

The script is available here (via Google Docs) or is copy/ pasted below;

  v_ViewLabel     n_view_column_templates.view_label%TYPE := 'GMD_Recipes'; -- Must be direct value from table n_views, case sensitive!
