But, this time the code also contains a WHEN OTHERS exception handler which deals with the apex_application.e_stop_apex_engine used by apex_application.stop_apex_engine. After another great year, we've been shortlisted in the Database & Systems Partners of the Year categorie.. This example also tells the browser to redirect to. Items are typically HTML form elements such as text fields, select lists, and check boxes. When you create a new form item using a wizard, the wizard uses a standard naming format. The naming format provides a handle so you can retrieve the value of the item later on. APEX_UTILS Need some data first: CREATE TABLE t ( some_text VARCHAR2(10) ); INSERT INTO t ( some_text ) SELECT dbms_random.string( 'a', 10 ) some_text FROM dual. Using multiple Authentication Schemes for your APEX application. Use this parameter to include HTML before every item help text for item level help. Note this parameter is ignored if p_show_item_help is set to 'NO'. First we create a SQL report on a page. The SQL should be similar to the following. Note that we are using index number 1 for the checkbox values. Create a page that will be your application help page. Create a region of type 'PL/SQL Dynamic Content' and add the APEX_APPLICATION.HELP call as PL/SQL Source. Note that check boxes displayed using APEX_ITEM.CHECKBOX only contain values in the APEX_APPLICATION arrays for those rows which are checked. Unlike other items ( TEXT, TEXTAREA, and DATE_POPUP ) which can contain an entry in the corresponding APEX_APPLICATION array for every row submitted, a check box only has an entry in the APEX_APPLICATION array if it is selected. Application Express provides the APEX_APPLICATION.G_F01 to

2 G_F50 arrays for this purpose. Each item you programmatically create is given an index value between 1 and 50 which directly corresponds to a G_Fx array temporarily containing the value (or values if multiple iterations of an item are generated) when the page submits. These can then be easily referenced in your PL/SQL code. Real World SQL and PL/SQL: Advice from the Experts. Scripting on this page enhances content navigation, but does not change the content in any way. APEX Application for Managing Other APEX Application Properties in Your Workspace. This function outputs page and item level help text as formatted HTML. You can also use it to customize how help information is displayed in your application. Refers to the home page of an application. The Application Express engine redirects to this location if no page is given and if no alternative page is dictated by the authentication scheme's logic. BTW, as you can read here, you can't use this PL/SQL table() construct inside a DML statement. So you can't use it directly in an insert, update, delete or merge command as that will result in an " ORA Invalid datatype " error. It would be really, really nice if that limitation is lifted in a future version! Use this parameter to include HTML between the page level help text and item level help text. You can also use Oracle Application Express public utility functions to convert an array into a single value. The resulting string value is a colon-separated list of the array element values. For example: Oracle Cloud: Universal Credits. What you need to know.. considering using the services of an Oracle support expert should.

In the next blogpost I'm going to tell you what you need to change in your application to support hrurls. Stay tuned. new functions to escape json, regular expressions and css selectors. Sure why not! I thought I had already answered the question before, so I searched on the OTN forum but didn't find my posting. No problem, shouldn't be too hard to find the solution again. I you are not clear about my requirement please send me the mail so that i can explain in brief. I would be interested in your thought! Do you have ideas for improvement or a better solution? Add your remarks in the comment section!. change_subscription_ allows to change the address of a subscribed interactive report. I set up another demo and modified the Database Sample Application on apex.oracle.com to use above described techniques to show nice URLs. This was the longest development cycle ever in the history of APEX, upcoming versions will be delivered sooner again. The APEX Listener is the only one of the available Weblistener

3 options which is actively developed nowadays and therefor the only one supporting the new RESTful Webservices Option in Oracle APEX added benefit of this procedure is it will clear the cache for all. Cool!! Now you only have to get rid of:. Now instead of having inline PL/SQL code here, we could call a procedure:. the provided username. This procedure can be used with the. I had to remove the apex_item.checkbox( p_idx=>20, p_value=> col ) from my code and just call the column as NULL in the query. Then put the html in the HTML elements in the form attributes and voila works great. Thanks a million. For now, only 1 module doesn't work; I found out how the apex_application.g_fxx arrays work. That's fine. Somehow, if I create a new module, it doesnt include the ADMIN_USER (in my case: VERVALLEN_IND) column. If I ad it myself, I get the failure message Error in mru internal routine: ORA-20001: no data found in tabular form Unable to process update. I am curious to know! So now, I think my problem is: why doesn't the select-statement include the column VERVALLEN_IND?? I was looking for your adres; can you send me it? Thanks! Niels. Which Tabular Form Column is mapped to which Apex_Application.g_fxx array? In the second FOR LOOP it will set the Y(es) flag for all those records where we now have a checked checkbox. Since we haven't specified any URI Prefix and use {path} as sole URI Template this Webservice will act in a catch-all way. I too like using the wizard generated MRU for all the reasons you mention. Good job on explaining how to implement the checkbox. This implementation of checkbox is a great tool for the toolbox. Thanks! Change the order and the "Display As" of the columns how you want to have them. thanks a lot for the typo, I have fixed it. Step 5 adds the HTML tag to render a checkbox. I can't seem to get this to work, i.e. in my case the new 'case'-column along with the HTML Expression (#COLUMN_NAME#) doesn't render a checkbox but instead simply a column rendering value 'checked="checked"' even if I set Display as 'Text Field' and add reference table + column in Tabular Form Element section. Could it be this solution doesn't work in Apex 3.2? Otherwise, any idea what I'm doing wrong here? I had to remove the apex_item.checkbox( p_idx=>20, p_value=> col ) from my code and just call the column as NULL in the query. Then put the html in the HTML elements in the form attributes and voila works great. Thanks a million. -- Note: g_f40 is the checkbox column ADMIN_USER_CHECKBOX. The other APEX URL Parameters could be coded into the URL as well, its just a matter of what you actually want to see in the URL. Session will always be zero, since this solution will work for public pages only (for now). Why don't I just use the APEX_Item.Checkbox function in the SQL statement,

4 instead of using my hand written HTML code in the HTML Expression? So using that foreign key value i need to show the checkboxes selected(for whom the values stored in the database columns). For now, only 1 module doesn't work; I found out how the apex_application.g_fxx arrays work. That's fine. Somehow, if I create a new module, it doesnt include the ADMIN_USER (in my case: VERVALLEN_IND) column. If I ad it myself, I get the failure message Error in mru internal routine: ORA-20001: no data found in tabular form Unable to process update. I am curious to know!

I you are not clear about my requirement please send me the mail so that i can explain in brief. Would you store those values in an application context? So it is available when you navigate to other pages or appilcation? I am especially concerned about the session id. Because we have synchronized the hidden ADMIN_USER column array with the checkbox selection, the standard ApplyMRU process will consider the values as if the user had manually entered them in a normal text field. Is this possible in combination with glassfish and ords? Thanks. How to achieve all this. Can u show me the way to get. (2) Column definition Display As: Text Field Element Attributes: class="js_checkbox". Hi Patrick, I found out what it was myself (while 're-styling' other modules): In Report Attributes: the column with the indication Y/N (in your example ADMIN_USER) should be displayed as 'Textfield' in Tabular Form Element and not 'Standard Report Column'. Also fill in tablename and columnname. Then it works fine! Sorry for the hassle, but it was very educative! Ciao Niels. Another advantage of this synchronization technique is that the g_f04 array, which is mapped to the flag column ADMIN_USER has the same array indexing as the normal columns. It allows to write simpler validations code, because all values of the same row are located on the same index position in all the g_fxx arrays! I am using this solution but i have a problem, because i have 24 checkbox (1 for 1 hours of day) in this case i have 24 APEX_Application.g_f04(ii) and 24 f40.count If I add others 4 fields (ID, Name,LastName, empno) i have more than 50. In this case when you try to use APEX_Application.g_f5x you get a error. Line 18 gives us the customer report on Page 2 (in debug mode, apparently).
