How to create an APEX 4.1 session?

Hi,
I've successfully used the mechanism described by [this thread|https://forums.oracle.com/forums/thread.jspa?threadID=663227] to create an APEX session in release 3.1.
We've recently been forced to move onto Oracle 11g and APEX 4.1. The session routine no longer appears to work:
- after setting up the session a call to the create_collection_from_query results in an error stating 'Invalid parsing schema for current workspace Id';
- the apex_application.g_instance value is changing - post_login changes the value and show loses the value;
Any ideas?

Hi Scott
Bad news. I read several time this thread, but I have not found error in my program ... .
And I can not see what are really doing APIs of APEX.
Time is going - so we have make a decision now.
Probably (as I have no more answers at this forum) - we can not use APEX (as nobody using APEX sessions as I asked),
as we can not manage its sessions programmatically (too risky).
Thanks for your answer.

How to create an apex collection to store and loop through the values

I couldn't find any simple example to do this
Apex 4.2
I need to create an apex collection. I have a query that returns multiple roles for a user. I need to check to see if one of my item values is within the collection but am not sure how to do so. So far I have:
begin
APEX_COLLECTION.CREATE_COLLECTION (
p_collection_name => 'ALL_ROLES');
select count(granted_role) into count from dba_role_privs where upper(grantee) = upper(:APP_USER);
end;
How would I store the query results in the collection?

Trying to understand your code and a better suggestion:
declare
is_viewable boolean;
v_count number;
l_query varchar2(2000);
i_counter number(10) :=1;
begin
--l_query := 'select granted_role from dba_role_privs where upper(grantee) = upper(:APP_USER)';
--why do you need a collection, this is a simple select count(1) question
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY (
p_collection_name => 'ALL_ROLES',
p_query => l_query,
p_generate_md5 => 'YES');
-- You create a collection, but where are you using it?
-- select count(granted_role) into count from dba_role_privs where upper(grantee) = upper(:APP_USER);
-- discard the above code
-- If you want to see how many elements in a collection
-- determine # of elements in a collection
http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_collection.htm#CJAFFEAH
v_count := APEX_COLLECTION.COLLECTION_MEMBER_COUNT ('ALL_ROLES');
IF :P32_SUBMISSION_DATE IS NOT NULL THEN
begin
select count(granted_role) into v_count
     from dba_role_privs
where upper(grantee) = upper(:APP_USER) and
    granted_role in ('SURVEY_SUID','SURVEY_JOB_SUID');

when no_rows_found then
    v_count := 0;
end;
if v_count > 0 then
    is_viewable := true;
else

How to create an Apex 3.1 a session context programmatically?

Hi
I want to do some unit testing on some pl/sql procedures that use apex collections. As I am using PL/SQL Developer and I am not connected to the database via Apex, inevitably they fail with the error "invalid parsing schema for the current workspace ID".
How can I create programmatically a session in Apex so I can unit test my code? I am sure I have seen code to do it, but cannot find it anywhere.
Thanks
Luis

Scott
Thanks for the help!
You say "uncomment the last line if you need to". How do I know if I need to? If the connected user is different from the application parsing schema?
In any case, the connect user is the same as the app parsing schema, and when I ran it without uncommenting that last line I got the error:
ORA-20104: create_collection_from_query_b Error:ORA-20001: Invalid parsing schema for current workspace ID
ORA-06512: at "FLOWS_030100.WWV_FLOW_COLLECTION", line 1223
Then I uncommented it (I granted execute to the package beforehand) but got the same error.
As I said, I am connected as the same database user as the application parsing schema, and the application does not require authentication. Where did it go wrong?
Please see below the code I am using.
Thanks
Luis

How to create an apex session in e.g. SQL*Plus?

I would like to establish an apex session using a tool different from SQL Workshop.
How can I achieve this using e.g. SQL*Plus or SQL Developer?
Is there some document on the internet which addresses this question? I couldn't find it yet.

First and foremost you need to set the Security Group ID (SGID)
begin
APEX_UTIL.SET_SECURITY_GROUP_ID(APEX_UTIL.FIND_SECURITY_GROUP_ID('MY_WORKSPACE')); -- replace MY_WORKSPACE with yours
end;
then you might need to set an application_id for certain features to work:
select application_id
    into apex_application.g_flow_id
    from apex_applications
   where application_name = 'my_app_name'; -- replace my_app_name with yours
If you need to create a session id, you can get a fresh one with
DECLARE
VAL NUMBER;
BEGIN
VAL := APEX_CUSTOM_AUTH.GET_NEXT_SESSION_ID;
END;

How to create temp Sequence for multi sessions

Hi,
I"m using Global Temp table and I need to insert Identity (or Seq-Number) column into it, but I also have multiple sessions for my sp and each case shold have it's own Seq-Number, starting from 0.
Is there any kind of "temp sequence" in Oracle ? that works in the same fashion like GTT , so multiple sessions each will get fresh zero anytime they will refer it.
I also found out that ROWNUM will not work in my case.
Probably I also can create SEQUENCE in my sp with some unique name let say with SID , something like:
select sys_context('SID') into tmp_SID from dual ;
CREAT SEQUENCE 'MYSEQ'||tmp_SID start with 0 .....
Tx
Trent

if several sessions will create sequence with same static name could it be collission ? Should I go with dynamic sequence name instead ?You cannot have the same SEQUENCE (i.e. "static name") created from multiple sessions. A SEQUENCE is a Database Object that is not transient, but permanent (until it is dropped).
Although you could "generate" dynamic sequence names and use them, you should look for a better implementation than running CREATE and DROP statements like that.
Furthermore, you would have difficulty in doing a bulk insert of multiple rows unless you add a trigger that fires FOR EACH ROW.
If you need to assign an increasing value to each row, use a ROWNUM to assign to a new column.
insert /*+ -- optional APPEND -- */ into target_table
select s2.*, rownum-0 from (select * source_table s where ..... order by ....) s2on the assumption that target_table as n+1 columns where the last column is for the increasing value. (rownum-0 is to set the first row to 0).

correcteed the SQL statement

I must be missing something...is there a video that teaches how to create, save and open a session?

I just don't seem to get it. Opening an old session seems difficult if you can't remember the specific name. Files in those sessions are not saved it seems unless you save each one individually. (Am I wrong here) Can someone help this early morning radio guy...I must be missing a step but I can't figure it out.

I have that problem sometimes, too. Personally I put it down to my age!

Audition won't let you close a session with unsaved files without putting up a warning about it - and you get an option to save all of them. By default, files get put in the {session name}_Recorded file with the sesx file (the session information) in the root folder. In there as well you can get Bounced file folders, and also one for mixdowns. When you first create a session, you get to choose the path you use, and everything else just occurs in a structure beneath that, which you can add to if you want. Whenever you need to save things, you get a browse option as well - worth using that first.
I really don't think it's that difficult, and the new scheme (yes it's not quite like the previous version) seems to work fine. With the best will in the world, Adobe can't compensate for anybody's amnesia though! Since there isn't a particular limit on what name you give your sessions, then the best thing to do if you're likely to forget is to give them longer, more meaningful names - and make sure that the folder they're in has the same name. Also, try to keep a relatively flat folder structure - in other words, don't have them nested several layers deep in a huge tree structure - that never helps.

Urgent : How to create a new variable in session context

Hi all
I am using JDeveloper 11.1.1.2.0 and am implementing adf security using WLS
I am loging in using loginame. and I am able to retieve the login_name in VO's using adf.context.securityContext.userName
My requirement is I want to set id (number datatype) in sessioncontext as userId.
The id should be taken from the database table according to the login_name and set in sessioncontext.
I want to populate the VO's in my various pages using this userId in session,since our tables are based on Id not login_name
Please help,its an urgent requirement

Hi,
Can u give me the code for getApplicationModuleForDataControl(DataControl dc)?
What is the '*u*' in u.getPageFlowScopeAttribute("userid"));?oh.. refer my following code.
    public static final ADFLogger LOGGER =
        ADFLogger.createADFLogger(Util.class);
    public ApplicationModule getApplicationModuleForDataControl(String dcName) {
        DCDataControl dcControl =
            getDCBindingContainer().findDataControl(dcName);
        if (dcControl == null) {
            logSevere(String.format("getApplicationModuleForDataControl(String dcName) : DCDataControl [%s] not found",
                                    dcName));
            return null;
        return dcControl.getApplicationModule();
    public BindingContainer getBindingContainer() {
        return getBindingContext().getCurrentBindingsEntry();
    public DCBindingContainer getDCBindingContainer() {
        return (DCBindingContainer)getBindingContainer();
public String getUserIdFromLoginName(String loginName){
        ApplicationModule am = getApplicationModuleForDataControl("Users_DataControl");
        ViewObject vo = am.findViewObject("Users_VO1");
                vo.setNamedWhereClauseParam("B_LOGIN_NAME",
                                    loginName);
        vo.executeQuery();
            Row row = vo.first();
            if (row == null) {
                return null;
            } else {
            return row.getAttribute("UserId")==null ? null : row.getAttribute("UserId").toString();
    private static void logSevere(String msg) {
        LOGGER.log(Level.SEVERE, msg);
public void setUserIdInSessionForLoginLoginName(String loginName){
String userId=getUserIdFromLoginName(loginName);
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("userid", userId);
}where as accessing the session in adf bc layer is conserned you can use ADFContext, which will help you to access the session(HttpSession) attributes.
import oracle.adf.share.ADFContext;
Object obj = ADFContext.getCurrent().getSessionScope().get("userBean");Regards,

How to create a session variable in Apex?

Hello colleagues,
Is there someone do know how to create a session variable in Apex?
How to get them?
Thanks
Best Regards

Hello,
What do you mean by 'session variable'? You mean something that stores the value int he users session state?
I really recommend reading the 2-Day Developer guide documentation, there is a complete section on session state -

How to create a fixed-width column within an APEX 4 interactive report?

This thread is a follow-up to {message:id=9191195}. Thanks fac586.
Partial success: The following code provided by fac586 limits the column width of the Apex 4 interactive report column as long as the column data contains whitespace within a Firefox 3.6 browser:
<pre class="jive-pre">
<style type="text/css">
th#T_DESCRIPTION {
width: 300px;
td[headers="T_DESCRIPTION"] {
width: 300px;
word-wrap: break-word;
</style>
</pre>
Notes:
1. The code above is put into the HTML header section for the page.
2. T_DESCRIPTION is defined as VARCHAR2(2000).
3. The code above works within the Firefox 3.6.12 browser but does not work within the Internet Explorer 7.0.5730.13 browser.
I tried adding "float: left;":
<pre class="jive-pre">
<style type="text/css">
th#T_DESCRIPTION {
width: 300px;
td[headers="T_DESCRIPTION"] {
width: 300px;
word-wrap: break-word;
<font color="red"> float: left;</font>
</style>
</pre>
Notes:
1. "float: left;" does not require whitespace and successfully splits the column between characters in lieu of whitespace.
2. "float: left;" shrinks the cell height and allows the page background to show through... couldn't determine how to fix this.
3. The code above works within the Firefox 3.6.12 browser but does not work within the Internet Explorer 7.0.5730.13 browser.
I've done some more research, but I still haven't discovered how to create a fixed-width column within an APEX 4 interactive report that displays properly within an Internet Explorer 7 browser.
Any ideas and help will be appreciated.

Thanks for your help with this!
<pre class="jive-pre">
what theme are you using?
</pre>
A customized version of theme 15.
<pre class="jive-pre">
Floating a table cell makes no sense (to me anyway).
</pre>
You are correct. I was just trying a different approach ... trying to think out of the box.
<pre class="jive-pre">
Think you'll need to create an example on apex.oracle.com with sample data
if there are any further problems.
</pre>
Great suggestion! The code your provided works in the Firefox 3.6.12 browser, but still doesn't work within my Internet Explorer 7.0.5730.13 browser.
UPDATE:
I have recreated the problem at apex.oracle.com, you can use the following information to check it out:
URL: http://apex.oracle.com/pls/apex/f?p=43543:100::::::
Workspace: IR_FIXED_WIDTH_COLS
Username: GUEST
Password: Thx4help
Application: 43543 - CM_RANDY_SD
Note: Table name is TEST_DATA
The following code provided by fac586 works in both Firefox 3.6 and IE7 using default theme "21. Scarlet" at apex.oracle.com; however, it doesn't work when I use a copy of our customized theme "101. Light Blue":
<pre class="jive-pre">
<style type="text/css">
.apexir_WORKSHEET_DATA {
th#T_DESCRIPTION {
width: 300px;
max-width: 300px;
td[headers="T_DESCRIPTION"] {
max-width: 300px;
word-wrap: break-word;
</style>

</pre>
Any idea what in the theme could be causing the fixed width column to be ignored in IE 7?

How to create a new session in JSP file

Usually a child IE window uses same session with parent window. Dose someone know how to create a new session when creating a new IE window by clicking a URL in parent window? The web page is writen by jsp file.

I am not sure of your question. Are you wanting to have 2 Session objects (one for the parent window and another for the child)?
A session is usually created once per client and is stored on the server the session id is carried around in a cookie or a URL rewrite so that everytime the user submits a page you will be able to store/access information.
// this will create a new session object if one doesn't already exist.
HttpServletRequest.getSession( true );
Hope this helps
