HOW TO have LOV display values from a table not contained in parsing schema

I am using DAD to log in and have been able to get around the problems associated with the login schema being different than the parsing schema. However, I want to have a list of values to be shown to the user based on a table in the DAD schema that they log into rather than the parsing schema.
Anyone know how this might be done?

RETURN 'select xxxxxxx' does it

How to download a file from a table not in the parsing schema

We have a table in another schema which holds files in a blob column. I can create a form on this table and the file upload works fine. The file browse page item has the source as the blob column and storage type "BLOB column specified in Item Source attribute". The download link generated for the page shows a call to apex_util.get_blob_file and the parameters are correct. However, when you click on the link you get a Page Not Found 404 error. Same error in Apex 4.1.1. The plsql error is:
ORA-20544: Invalid table owner
ORA-06512: at "APEX_040000.WWV_FLOW_DML", line 1628
ORA-06512: at "APEX_040000.HTMLDB_UTIL", line 2244
ORA-06512: at line 31
Is there a way to use apex_util.get_blob_file to download a file when the table is in another schema?

Hi,
I am not sure that the post explains everything as the "Automatic Row Processing" and "Automatic Row Fetch" process work fine on this page and therefore security should not be an issue.
Thanks for the view suggestion, but I am not sure that a view is a good option for us because the parsing schema does not have create view privilege and therefore the view would be difficult to install and maintain. We will problably end up with a custom download file process.

How to get edited row values from ADF table?

JDev 11.
I have a table which is populated with data from Bean.
I need to save changes after user make changes in any table cell. InputText is defined for table column component.
I have defined ValueChangeListener for inputText field and AutoSubmit=true. So when user change value in inputText field, method is called:
public void SaveMaterial(ValueChangeEvent valueChangeEvent) {
getSelectedRow();
SaveMaterial(material);
This method should call getSelectedRow which take values from selected table row and save them into object:
private Row getSelectedRow(){
RichTable table = this.getMaterialTable();
Iterator selection = table.getSelectedRowKeys().iterator();
while (selection.hasNext())
Object key = selection.next();
table.setRowKey(key);
Object o = table.getRowData();
material = (MATERIAL) o;
System.out.println("Selected Material Desc = "+material.getEnumb());
return null;
Problem is that getSelectedRow method doesnt get new (edited) values, old values are still used.
I have tried to use ActiveButton with same method and it works fine in that case. New values are selected from active row and inserted into object.
JSF:
<af:table var="row" rowSelection="single" columnSelection="single"
value="#{ManageWO.material}" binding="#{ManageWO.materialTable}">
<af:column sortable="false" headerText="E-number">
<af:inputText value="#{row.enumb}" valueChangeListener="#{ManageWO.SaveMaterial}" autoSubmit="true"/>
</af:column>
<af:column sortable="false" headerText="Description">
<af:inputText value="#{row.desc}" valueChangeListener="#{ManageWO.SaveMaterial}" autoSubmit="true"/>
</af:column>
</af:table>
<af:activeCommandToolbarButton text="Save" action="#{ManageWO.EditData}"/>
What is a correct place from where save method should be called to get new (edited) values from ADF table?
Thanks.

Did you look into the valueChangeEvent?
It has oldValue and newValue attributes.
public void SaveMaterial(ValueChangeEvent valueChangeEvent) {
Object oldVal = valueChangeEvent.getOldValue();
Object newVal = valueChangeEvent.getNewValue();
// check if you see what you are looking for.....
getSelectedRow();
SaveMaterial(material);
}Timo

How to refresh lov displayed value

Hi,
I have a POPUP LOV (which displays a numeric id and description) and it has cascading parent LOV. When I change the value in the parent LOV the child LOV is populated with new values and that is OK. But, I also want to automatically select some value from that LOV according to some rule. How can I do this? I tried with dinamic actions "set value" but only the session value of the item changes and the popup stays the same (no value selected).
Thanks

I wonder if more people agree with your statement that this would be the natural thing to do.
Everybody knows Excel, and wants Excel behaviour. This behaviour is just like Excel. You search for 2251343000 in a formatted column, not 2,251,343,000. It's way easier to type 2251343000 on the numeric keyboard.
(Just tried if you can filter on a unformatted hidden column somehow, but that doesn't seem to work. Sorry, no solution from me then.)

How to dynamically get default value from a table column

Hi all,
Here's my problem: Our front end application sends insert and update queries to a pl/sql package. I've got a procedure that gets a PL/SQL table with all the column names an values, a table-name and a primary key name and value. That procedure creates an insert or update statement. So far, so good.
Now the problem: our front end doesn't know what the default value for a column is. So when a number field doesn't get a value in the front-end, it's inserted with a value '0' though is should ben NULL. My sollution for this is to know the default value of a column: when there's a default of '0', then the value that will be inserted is '0'. When there's no default value and the column can ben NULL, it'll be inserted as NULL. if the column has a not null constraint, a '0' will be inserted.
Ofcourse I can get the default value from the system-views all_tab_columns or user_tab_columns, but our application is installed at some 100 clients, and has various database installations. Most of the times, the tables are in the same schema as our procedure that performs the insert or update, but sometimes some of the tables are in another schema (in the same database) and also sometimes some tables are stored in another database. In all these situations, a synonym for that table exists in the schema.
Is there a api function or procedure that I can call to get the default value of a column? I looked at dbms_sql and dbms_metadata, but those packages don't give me that perticular information. if not, I'll stuck with the 'does table exists in schema' yes->use table, no query user_synonyms to look for the owner of the table (and database link) and query all_tab_columns to get the default value. Only this seems a bit overkill to me.
I hope I'm clear enough? And please don't reply with "don't do inserts this way"! I know, this is not the most optimal sollution, but it does gives us a couple of advantages in our application...

there is no way that I can think of, apart from what you have already discovered (i.e. views), where you can determine if a column has a defuault value defined against it.
The other option is triggers, but I guess doing that across 600 tables would not be an option, and besides I stay clear of triggers.
A different approach therefore, if you cannot pre-determine the data, is to consider a post problem handler, hence I suggested the use of an exception handler.
The exception handler works regardless of whether the statement is dynamic or not.
SQL> truncate table abc;
Table truncated.
SQL>
SQL> declare
2    NULLVAL exception;
3    pragma exception_init(NULLVAL, -01400);
4
5 begin
6
7    begin
8
9      execute immediate 'insert into abc (y) values (1)';
10
11      exception
12        when NULLVAL then
13          -- handle the error
14          execute immediate 'insert into abc (x,y) values (0,1)';
15
16    end;
17
18    commit;
19
20 end;
21 /
PL/SQL procedure successfully completed.

How to get lov display value dynamically for an item according to date pick

Hi friends,
I have a date picker item called on_date, and also one lov item course_name
If i select one date from the date picker item means, automatically the course name corresponding to the date has to populate in the course_name item lov.
suppose if i select the date (21-06-2011) from the date picker item means and if there are two courses available for the date in the table
that is *) APEX *)OAF means, then the course_name item lov should show APEX and OAF in the select list.
How to acheive it.
I tried it in the way by creating a dynamic action for the date item
True Action: set value
Sql Expression:
select course_name from xx_trg_course_detail where :P2_ON_DATE between effective_start_date and effective_end_datepage item to submit: P2_ON_DATE
Affected element: P2_COURSE_NAME
it is working if i kept the course_name item as a text field instead of LOV item.
But i need to show the corresponding courses in the lov for the course_name item soon after selecting the particular date from the date picker.
This is the LOV definition that i gave for the course_name item
select course_name r, course_name d from xx_trg_course_detail where :P2_ON_DATE between effective_start_date and effective_end_datewhat is the problem over here.
Thanks
Regards,
Mini
Edited by: Mini on Jun 22, 2011 2:45 AM

Hi friends,
One of my batch mate corrected this problem, by setting
cascading LOV parent item: P2_ON_DATE
page items to submit : P2_ON_DATE
By specifying the date picker item name in the above fields for the item COURSE_NAME.
Now if i select the date from the picker means, the lov item course_name is getting changed as it is showing only the courses of the respective dates.
Thanks

How to display value from unlinked table

Hello,
In most of my report, I use at least 1 unlinked table that only have 1 row, which is mostly generic information like a logo or company name that I use in the header.
This work well as long as there is at least 1 record in all other table, if not then my header will be empty.
It seem to be related to the crossjoin between all table, but I was wondering if there was an easy was to accomplished this goal without having to link my "Company Info" table to the other one
Thank
ML

Put your logo in a subreport, then you can suppress if no data etc.
CR is a Relational Database reporting tool, it requires the tables to be linked otherwise there are 2 SELECT statements generated and unknown results...

You could set the table's data model to be the same:
output2.setModel( output1.getModel() );

How to truncate the values from the table

Hi All,
I am working on an issue..where we are first deleting all the records from the table and then based on few conditions we are putting the records back in that table...when we tried to run this program along with few others those who are doing almost the same stuff we are having issues...we tried to schedule few jobs related to these programs only...but after a ceratin amount of time couple of jobs got canceled...I was talking to my basis guy and he said the problem is ratehr then truncating the records from the table we are deleting the records and it's taking lots and lots of space to execute...so we need to truncate the records from the table insted of deleting it...we are using the following the statement right now:
    DELETE FROM ZTUS_PG.
    COMMIT WORK.
So can you please tell me how can we truncate the values from this table instead of just deleting them and what would be effect of this.
Thanks,
Rajeev Gupta

I don't think basis is saying you should delete all the records from the table. They are saying remove the table and it's contents (a much faster thing to do). I'm not sure this the right thing to do, but you can have a look at:
http://publib.boulder.ibm.com/infocenter/db2luw/v9/index.jsp?topic=/com.ibm.db2.udb.apdv.sample.doc/doc/admin_scripts/s-truncate-db2.htm
Something like:
EXEC SQL.
TRUNCATE TABLE ZTUS_PG REUSE STORAGE
ENDEXEC.
COMMIT WORK.                      "Empty table is committed here

Passing value from event to workflow container

Hi experts,
I have triggered a workflow using SAP_WAPI_CREATE_EVENT fm. I have declared 3 parameters in the BO for the event. Similarly i have created the 3 parameters in workflow container to receive the values.When the user clicks a button i trigger the workflow using the fm. I have to pass values of these 3 parameters to 3 parameters of the workflow container. Can you please tell me how should i pass the value from event to workflow container. Is there any way i can set workflow container parameter values while calling the fm itself.

INPUT_CONTAINER LIKE SWR_CONT Input container (name-value pairs)
The above tables parameter is used to transfer the values from FM to workflow.
declare a internal table of type SWR_CONT
DATA:
lt_cont TYPE STANDARD TABLE OF swr_cont,
ls_cont TYPE swr_cont.
ls_cont-element = 'ELEMENT NAME 1'.
ls_cont-value = <Variable which holds the value>
APPEND ls_cont TO lt_cont.
ls_cont-element = 'ELEMENT NAME 2'.
ls_cont-value = <Variable which holds the value>
APPEND ls_cont TO lt_cont.
ls_cont-element = 'ELEMENT NAME 3'.
ls_cont-value = <Variable which holds the value>
APPEND ls_cont TO lt_cont.
pass lt_cont to the parameter INPUT_CONTAINER

How to retrieve 2 values from a table in a LOV

Hi
I'm pretty new to APEX. I try to retrieve two values from a table using a LOV. I have a table named DEBIT with then columns SITE, NAME and KEY
I want to display NAME to the user in a list. When the user select an item from the list, I want to retrieve the data of the SITE and KEY column of this item in order to launch an SQL command based on this two values.
How to retrieve thes two values whant the user chooses an item from the list ?
I apologize for my english, being french.
Regards.
Christian

Christian,
From what I understood about your requirement, you want a 'select list with submit' which displays "NAME" and based on the value selected, you want to get the corresponding values for "SITE" and "KEY" from the table.
Step 1: Create a select list with submit, say P1_MYSELECT 
Use something like this in the dynamic list of values for the select list: 
SELECT NAME display_value, NAME return_value
FROM DEBIT 
Step 2: Create a page process of type PL/SQL block. Also create 2 hidden items P1_KEY and P1_SITE. 
In the PL/sQL, write something like:
DECLARE
v_key DEBIT.KEY%TYPE;
v_site DEBIT.SITE%TYPE;
CURSOR v_cur_myvals IS
 SELECT KEY, SITE
 FROM DEBIT
 WHERE NAME = :P1_MYSELECT;
BEGIN
OPEN v_cur_myvals;
LOOP
 FETCH v_cur_myvals
 INTO v_key,v_site;
 EXIT WHEN v_cur_myvals%NOTFOUND;
:P1_KEY := v_key;
:P1_SITE := v_site;
END LOOP;
CLOSE v_cur_myvals;
END; 
Then you can use these values for whatever purpose you need to.
Hope this helps.

hi,
use the set_attribute( ) method now to set the attribute with a particular key eg HIGH in ur case
// u can use the code wizard( control +f7) this code will be auto generated when u select the
//radio button to read the context node
DATA lo_nd_cn_node TYPE REF TO if_wd_context_node.
DATA lo_el_cn_node TYPE REF TO if_wd_context_element.
DATA ls_cn_node TYPE wd_this->element_cn_node.
* navigate from <CONTEXT> to <CN_NODE> via lead selection
lo_nd_cn_node = wd_context->get_child_node( name = wd_this->wdctx_cn_node ).
* get element via lead selection
lo_el_cn_node = lo_nd_cn_node->get_element( ).
* set single attribute
lo_el_cn_node->set_attribute(
name = `ATTribute name.`
value = 'LOW' ).
it will solve ur query ..

How to display the values from the table in the screen

Hi,
I have created a screen where i will enter the values for the field treshold amount and desc and if i press update button .it will update the new values by overriting the existing values .
Now i have got requirement i need to create a button show which will display the existing value from the table. always there will be only one entry...in this table
Please can one give me idea...to do this
or sample code...thanks in advance
regards
paveeeeee

Define a function code 'SHOW' for your button. In your PAI module, when you check for various sy-ucomms, check for 'SHOW' also.
Your code will be like this:
Case sy-ucomm.
when 'SHOW'.
perform show_details.
endcase.
In the perform, you can fetch the data from the table and put it in global variables. In the PBO, move the data from the global variables to the screen fields so that they get displayed on the screen.
Hope this helps. Reward points for useful answers.

How can I get dataTable to display values from the java layer?

When I use the dataTAble in my JSP page it will only display values from my java layer if the facets tag has it's name set to "header". Why is this happening?
If I set it to "header" and I look at the page source it actually has created the correct number of rows but it doesn't put the values between the <td> tags? It see's the length of my list but it doesn't pick the values out of the list.
<h:dataTable var="data" value="#{NameBean.test}" border="1">
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
</h:column>
<h:column>
<f:facet name="header">

<h:outputText styleClass="outputText" value="#{NameBean.test}" style="" rendered="true" escape="false"/>
</f:facet>
</h:column>
</h:dataTable>
public List gettest()
 List li = new LinkedList();
 Object Developers[] = {"M@n00j", "sdsadas"};
 for( int i = 0; i < Developers.length; i++ )
 li.add(Developers);
 return li;
Thanks in advance to anyone that can help.

I've been able to get it working with some of those changes along with changes in the JSP. I think it's a setting or two in the JSP that'll allow the program to run correctly.
I have a list and it's returned like what you suggested. A day or two ago I tried to move the outputtext outside of the facet tag but nothing would print, I know believe that's related to the following setting in the JSP:
rows="0" in the <h:dataTAble tag
Unfortunately the dataTAble isn't displaying the values correctly. It prints all of the values (Strings) in the list on each row and it make a new row for the number of items in the list.......... ???
Here's what it's printing to the screen (the table):
===================
== [asdasd], [sddfdfd] ==
===================
===================
== [asdasd], [sddfdfd]==
===================
what it should print:
============
== [asdasd] ==
============
============
== [sddfdfd] ==
============
My code:
public List gettest()
 List li = new ArrayList();
 li.add("asdasd");
 li.add("affffd");
 return li;
 }JSP
<h:dataTable border="1" columnClasses="list-column-left"
 headerClass="list-header"
 rowClasses="list-row-odd"
 id="table"
 rows="0"
 value="#{NameBean.test}"
 var="data">
<h:column>
<f:facet name="header">
<h:outputText value="test"/>
</f:facet>
<h:outputText value="#{NameBean.test}" style="" rendered="true" escape="false"/>
</h:column>
