How to populate field on page with Primary Key value from previous page

I am trying to create a patient tracking system for a group of doctors. There is an add patient form based on the Patient table (which has Patient_Id as its primary key) which branches to a pre-operative assessment form. I would like to populate the pre-op assessment Patient_Id field with the Patient_Id generated by the Add Patient page during processing, which comes from the Patient_seq sequence. How can I do this? I have tried using a computation on the Pre-Op Assessment form, but no matter what I put in, the field remains blank.

Hi,
If I understand you correctly, once patient record is created you branching to next page (pre-operative assessment form). First create a static hidden item in patient form *:PX_PATIENT_ID_COPY*.
Create an On submit after computation and validation process in patient form to get the inserted patient_id from patient table. Here is the code -
SELECT patient_id into :PX_PATIENT_ID_COPY from patient_table where rownum=1
order by patient_id descI would not use the sequence to get the current value because if the inserted record been deleted from your patient table, sequence current value would not be valid to find that record in patient table.
Basically when the record been inserted, the process get the value and put into the hidden item.
Pass the value from the hidden item to the next page by setting them in page branch. Under the Action section in the page branch, Set this items field type - *:PX_PATIENT_ID* (next page item for patient_id). Type *&PX_PATIENT_ID_COPY.* in the with these values field. Make sure you include dot(.) after *&PX_PATIENT_ID_COPY*.
Give it a try now. Hope it would helps.

Readonly table with where clause value from previous page

Hi
I am using jdeveloper 10.1.3.
I have a globalhome page where the user enteres a reference number. i have a backing bean for the globalhome page that runs a method to run an sql that seraches for this reference number, if the reference number exsits the user is directed to a detail page.
this detail page should display details of this reference number.
i have set up a read only table to display this data based on a view object with a bind varaible in the where clause.
however i am unsure how to set this bind varaible value to the reference entered in the first globalhome page.
please can anyone advise how to do this.
regards

Hi,
You can follow following steps to achieve this
1) Write a custom method in your Application module like
public void executeMyVO(String bindVarValue)
MyVOImpl vo= getMyVo();
vo.setNamedWhereClauseParam(<bind variable name decalred in VO>,bindVarValue);
vo.execute();
2) Expose the above method to client. (Right click AM-->Client-->Shift method from left to right)
3) In the pagedef of globalhome page, create a method action for the aboce created custom method
4) execute the method action from your backing bean after you run an sql that seraches for this reference number.
Hope this help.

Need to get primary key value from entity

Hi,
I have 2 pages. In the first page on click of GO button, Im inserting data into table using EO and Immediately navigating to second page.
Primary Key value is generated in EOImpl java file.
In second screen, in the header region, I need to show the row inserted in table.
to query the VO, i need to have primary key generated in EOImpl.
Please let me know how can i get this value in either in PFR of first page or in PR of second page. Thanks.

Hi
have you included the eo that tyou are refering to in the header oif the second page..
if both pages are using the same AM, the data will appear.
at worse can you can get the ID from the eo using amethod in your AM.

How to get the auto increment integer primary key value of a new record

I have a DB table that has a auto increment integer primary key, if I insert a new record into it by SQL statement "INSERT INTO...", how can I get the integer primary key value of that newly created record?

Well maybe someone knows a better method, but one workaround would be to add a dummy field to your table. When a new record is inserted this dummy field will be null. Then you can select your record with SELECT keyField FROM yourTable WHERE dummyField IS NULL. Once you've got the key number, you then update the record with a non-null value in the dummyField. Bit of a bodge, but it should work...
Another alternative is, instead of using an Autonumbered key field, you could assign your own number by getting the MAX value of the existing keys (with SELECT MAX(keyField) FROM yourTable) and using that number + 1 for your new key. Might be a problem if you have lots of records and frequent deletions though.

Display the second report as modalform and filter with primary key value of first report when you click on first report column link

Hi All,
I have two reports.
1. order report
2. order detail report
when you click on the order report column it display the order detail report as a modal form.
i was done below steps.
1. In page header i was written the below code

Vijay,
Issue 1: Your usage of $s() JavaScript API seems to be wrong. For the first parameter, you need to use the name of the hidden page item and not p_order_id.
javascript:$s('P1_ORDER_ID','#ORDER_ID#');openForm1();
Issue 2: Seems like you are not setting the hidden page item's value in session state. Assuming your hidden page item is called P1_ORDER_ID, Under "Region Definition" tab of your "Order Detail Report" under "Source" tab, for page items to submit, enter the name of the hidden page item P1_ORDER_ID.
Thanks!

Target Spry RowID on page with Multiple data sets from another page

Hi all,
I am trying to target a specific data item, on a page with
multiple data sets, from a link on another page. (I also have to
pass the link through Flash, but lets start with the simple
part...)
You can take a look at the site in progress here:
http://www.3andband.com/TestSite/iframeTest3.html
From the Home page I want to link to specific news or concert
items on the News page
I have been trying to get SpryURLUtils to do it but I can't
seem to get it working.
Any help would be greatly appreciated.
Thanks!
Ben

did u try if it even passes the row value?? with a simple
alert? alert(params.row)
Also maby u need to reorder the scripts to this;
<script src="../SpryAssets/SpryURLUtils.js"
type="text/javascript"></script>
<script src="../SpryAssets/xpath.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryData.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryCollapsiblePanel.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryEffects.js"
type="text/javascript"></script>
<script src="../SpryAssets/SpryAccordion.js"
type="text/javascript"></script>
and your js script
var params = Spry.Utils.getLocationParamsAsObject();
var dsConcerts = new
Spry.Data.XMLDataSet("includes/concerts.xml", "Concerts/concert");
dsConcerts.setColumnType("image", "image");
var dsNews = new Spry.Data.XMLDataSet("includes/news.xml",
"News/item");
//Set an observer so that when the data is loaded, we update
the current row to the url param value
dsNews.addObserver({ onPostLoad: function(ds, type) {
dsNews.setCurrentRow(params.row); }
function MM_effectBlind(targetElement, duration, from, to,
toggle)
Spry.Effect.DoBlind(targetElement, {duration: duration,
from: from, to: to, toggle: toggle});
So url params get loaded before the data

How do I let user enter a primary key value on a form

I'm creating my first APEX application. I have a simple table called HOSTS with 2 columns HOSTNAME and IP_ADDRESS. HOSTNAME is the primary key for the table. HOSTNAME is a perfectly acceptable primary key and I don’t wish to create an additional column to be populated by a sequence.
What are my options for creating a form on the table without using "Existing trigger", "Custom PL/SQL function" or "Existing Sequence" to populate the primary key column, i.e. HOSTNAME, so that the user can enter a value for the primary key?
Any assistance greatly appreciated.
Gavin

The debate about natural keys versus surrogate keys
will no doubt continue with advocates for both sides.
However there is also a difference between
'making your life easier' for APEX development and
'making your life more difficult' by having to
analyse, implement and deploy a surrogate key only
approach to an existing database which employs both
natural keys and surrogate keys.
hould we be forced to change the database design
because a development tool does not cater for natural
primary keys?The application development product is TRYING to save you from shooting yourself in the foot. The idea is to separate the primary key from being accessed by the user or ANY carbon based unit.. The key is mainly used by the system to join and lookup data rows, not for people to change whenever they decide that the key is WRONG.
Think about this, if you use Last Name as a key in your system (a bad idea to begin with since this is NOT a unique id when you have two Smiths). When a person needs to change this because Jimmy Smith is NOT the only Smith working for Acme Toys, you have to cascade that change through all the child tables related to the main person table.
If instead you use a system generated key, no change will be required since the key has NO relation to the data other than it represents a pointer to that row of data.
Works for me, since I do not want to write all the supporting code when APEX builds it for you...
Thank you,

How to populate multiple text boxes by selecting a value from drop down

I apologize in advance if this is redundant, but I have searched this forum relentlessly to no avail. I have a form connected to an MS Access database. The database is linked to another datadase on an Advantage server. This is dynamic data that has an ODBC driver allowing to link access tables to the Advantage data. Macros on access updates the table being used on this form. The livecycle form connects to the access data via a DSN on a machine that uses acrobat (not reader). This is a physician office, this form should expedite ordering radiology tests on patients. The plan is to use a drop down to select a chart number that will trigger several text boxes to populate dynamically with the corresponding demographic values like name, age, insurance etc.
Using a data drop down I am able to select the chart number. When I used the example from the office supplies database, so that a button will trigger the event with the following code:
if (Len(Ltrim(Rtrim(SelectField.rawValue))) > 0) then
$sourceSet.DataConnection.#command.query.commandType = "text"
$sourceSet.DataConnection.#command.query.select.nodes.
item(0).value = Concat("Select * from OfficeSupplies Where ID = ", Ltrim(Rtrim(SelectField.rawValue)) ,"")
I recieve a syntax error, despite adjusting quotation since I am using text rather than numeric fields.
My question is the following:
Is there a simple javascript that I can use to populate these text boxes (which may be read only but would be better if it allows user input)? Or does anyone recommend an alternative method? I would be happy with a link that solves this problem if someone can provide. I am somewhat familiar with js but open to any suggesstion.
Thanks
PS this form could also be linked to a Sequel database if that offers an advantage.

The View object API has a setQurery() method that you can use to set the query as needed before executing it via executeQuery(). You can do this in a custom Application Module method exposed to its client interface and bound to the binding layer. You can call this method from your backing bean on a value change listener.

How to populate field catalogue fields in ALV using dynamic internal table

Hi All,
Please let me know how to populate field catalogue fields in ALV using dynamic internal table.
I have created <dyn_table> using code below.
CALL METHOD cl_alv_table_create=>create_dynamic_table
                 EXPORTING
                   it_fieldcatalog = g_t_ifc
                    it_fieldcatalog = g_t_fieldcat
                 IMPORTING
                    ep_table        = dy_table.
ASSIGN dy_table->* TO <dyn_table>.
Create dynamic work area and assign to FS
CREATE DATA dy_line LIKE LINE OF <dyn_table>.
ASSIGN dy_line->* TO <dyn_wa>.
Now this <dyn_table> has fields like idoc no.,creation date ,
segment field 1, segment field 2 etc..Now idoc no.,creation date are static fields from table EDIDC. And segment field 1, segment field 2 etc are dynamic fields from table EDSAPPL.
In my ALV report I am getting the final layout properly but I am unable to move values to corresponding fields in the final layout shown.Please let me know how to populate these fields from different tables.
I tried this way but its not working.
SORT g_t_edid4 BY docnum.
LOOP AT g_t_edidc INTO g_r_edidc.
    READ TABLE g_t_edid4 into g_r_edid4
                     WITH KEY docnum = g_r_edidc-docnum
                                    BINARY SEARCH.
    IF sy-subrc = 0.

   CLEAR g_r_edid4.
    ENDIF.
MOVE-CORRESPONDING g_r_edidc to <dyn_wa>.
APPEND <dyn_wa> TO <dyn_table>.

You have to assign each field to field symbol and then assign the value to that field symbol and asssign that field symbol to workarea field symbol.
LOOP AT g_t_edidc INTO g_r_edidc.
READ TABLE g_t_edid4 into g_r_edid4

ASSIGN COMPONENT 'SDATA' OF STRUCTURE <DYN_WA> TO <DYN_FLD>.
<DYN_FLD> = g_r_edid4-sdata.
" <dyn_wa> = g_r_edid4-sdata.
" Assign each fields like this.

How to populate fields "DocEntry" and "DocNum" in UDT? Those are not UDF.

I created a UDT with document type. When I populate the data, I don't know how to populate fields "DocEntry" and "DocNum". Those are not UDF. Here is my coding. Can somebody help me out?
Dim objUserTable As SAPbobsCOM.UserTable
                    objUserTable = objSBOAPI.oCompany.UserTables.Item("AIT_POSTRANS")
objUserTable.UserFields.Fields.Item("DocEntry").Value ="1000"
///////////// Error here "DocEntry" is not a UDF
                                       objUserTable.UserFields.Fields.Item("U_TrnsType").Value = "4"
                        objUserTable.UserFields.Fields.Item("U_CardCode").Value = objRecord.Fields.Item(0).Value
                        objUserTable.UserFields.Fields.Item("U_ShpBrnch").Value = objRecord.Fields.Item(1).Value.Replace("'", "")

Currently versions of the SDK (SBO2005A SP01, SBO2007A, SBO2005B, SBO2007B) does not support Data Support of UDO-tabeles using the DI-API... That means that you can only add data to such tables using the GUI,,,
This is currently a huge problem and the number one DI-API Development Request. The status with SAP is that this will become part of the SDK in SAP Business One 8.8 (the next major release), but 8.8 does not yet have a shipment date (My guess is that it will be 2009 before we even see it in rampup)...
I know some people have experimented with writing direct SQL to such tables and know it can be done, but be aware that SAP does NOT support it!... Personally I've never done it for that reason althoug it would have been nice to do if some situations...
Sorry I could not give anything better...

How can we export the Primary key values (along with other data) from an Advantage database?

One of our customers is moving from our application (which uses Advantage Database Server) to another application (which uses other database technology). They have asked us to help export their data, so that they can migrate it to another database system. So far, we have used the Advantage Data Architect (ARC32) "Export Table Structures as Code" functionality to generate SQL. We used the "Include existing data" option. The SQL contains the necessary code to recreate the tables and indexes. The customer's IT staff will alter the SQL statements as necessary for their new system.
However, there is an issue with the Primary Keys in these table. The resulting INSERT statements use AutoInc as the type for the Primary Key in each Table. These INSERT statements contains "DEFAULT" for the value of each of these AutoInc fields. The customer would like to output an integer value for each of these Primary Key values in order to maintain referential integrity in their new system.
So far, I have not found any feature of ARC32 that allows us to export the Primary Key values. We had been using an older version of ARC32, since our application does not use the latest version of ADS. I did download the latest version of ARC32 (11.10), but it does not appear to include any new functionality that would facilitate doing this sort of export.
Can somebody tell me if there is such a feature in ARC32?
Or, is there is another Advantage tool to facilitate what we are trying to accomplish?
If there are no Advantage tools to provide such functionality, what else would you suggest?

George,
It sounds like the approach you are using is the correct one. This seems to be the cleanest solution to me especially since the customer is able to modify the generated SQL statements for their new system.
In order to preserve the AutoInc values I would recommend altering the table and changing the field datatype from AutoInc to Integer. Then export the table as code which will export the actual values. After the tables have been created on the new system they can change the field datatype back to an AutoInc type if necessary.

Chris Franz

How to populate a table based on a row selection from another table.

Hi, i just started to use ADF BC and Faces. Could some one help me or point me a solution on the following scenario .
By using a search component , a table is being displayed as a search result. If i select any row in the resulted table , i need to populate an another table at the bottom of the same page from another view. These two tables are related by primary key . May i know how to populate a table based on a row selection from another table. Thanks

I understand your requirement and the tutorial doesn't talk about Association between the views so that you can create a Master-Detail or in DB parlance, a Parent-Child relationship.
I will assume that we are dealing with two entities here: Department and Employees where a particular Department has many Employees and hence a Parent-Child relationship.
Firstly, you need to create an Association between the two Entities - Department and Employees. You can do that by right clicking on the model's entity and then associating the two entities with the appropriate key say, DepartmentId.
Once you have done that, you need to link the two entities in the View section with this Association that you created. Then go to AppModule and make sure that in the Available View Objects: 'EmployeesView' appears under 'DepartmentView' as "EmployeesView via <link you created>". Shuttle the 'DepartmentView' to the right, Data Model and then shuttle
"EmployeesView via <link you created>" to the right, Data Model under 'DepartmentView'.
This will then be reflected in your Data Controls. After that, you simply would have to drag this View into your page as a Master-Detail form...and then when you run this page, any row selected in the Master table, would display the data in the Detail table.
Also, refer to this link: [Master-Detail|http://baigsorcl.blogspot.com/2010/03/creating-master-detail-form-in-adf.html]
Hope this helps.

Mapping in OWB with primary key and foreign key relationship

Hi all,
I am new to this datawarehousing field. I have just started my career. I have to now create a mapping in owb where a table has a field which is a primary key of another table in the same staging area. If you guys could help me out with the a method it can be created that would be very helpful to me.
I thought of 2 ideas,
1. If I can use a look up, but then I am not sure if i can use a lookup for primary key, foreign key relationship. If I can use also, I do not know how to use that.
2. What if I can directly take that the first table and link the primary key of that table to the second table which uses that primary key of the first table as one of its fields.
I do not know how feasible these methods are. Please guys help me out.
Thanks in advance.

I have a similar case where table a and table b having relation but table a got inserted with data and table b is empty so there no values for foriegn key column in table b to realte with table a.
Now i want to load table b foriegn key with primary key column values of table a.
how can we do this in owb
thanks

Developing a 2 page form, username on the 1st page, password on 2nd how can i force FF to use the username from previous page when it asks to remember acct info?

I am developing a 2 page signup form, where the person enters their username on the 1st page and password on the 2nd.
When I test the form, FF asks to remember my password for the site - however it thinks the zipcode (field above the password) is the username on the account.
I have tried to put their username/email in a hidden field on the 2nd page, just above the password field - and that did not work.
How can i force FF to use the username from previous page when it asks to remember acct info?

This website is using autocomplete=off to prevent Firefox from saving and filling the name and password.
You can remove autocomplete=off with a bookmarklet to make Firefox save names and passwords and other form data.

Another user has changed the row with primary key -Table changed externally

Hello,
I am facing the error: "Another user has changed the row with primary key oracle.jbo.Key[94 ]." during the delete operation.
User case scenario:
1. Added new row in the table.
2. Once new row is added to the the table, another application will update few columns in the newly added row based on some logic.
3. On the same session I am trying to delete the newly added row and getting above mentioned error.
I have added a "Button" in the table to partialRefresh the table to check the new values of the changed columns.
I have checked the forum and found many similar errors and tried the following but nothing helped.
1. By setting "Auto Refresh = True" for the view object.
Issue faced-> It worked fine but after few add and remove my db is getting to inconsistent state after which, I am not able to do any add/delete from my page.
Error: "Too many objects match the primary key oracle.jbo.Key". I have checked this and I am not getting this error when "Auto Refresh = False" even after multiple add and remove actions.
2. By Setting "Auto Refresh" the iterator associated with the page.
Issue -> Did not work at all.
Looking forward inputs from gurus.
Thanks
Abhijeet

Finally I found one solution to this problem at: [ http://www.avromroyfaderman.com/2008/05/bring-back-the-hobgoblin-dealing-with-rowinconsistentexception/|http://www.avromroyfaderman.com/2008/05/bring-back-the-hobgoblin-dealing-with-rowinconsistentexception/]
Simply overriding the lock() method in the entity object resolved issue. Kudos to the author.
Code:
public void lock() {
try {
super.lock();
} catch (RowInconsistentException e) {
refresh(REFRESH_WITH_DB_ONLY_IF_UNCHANGED | REFRESH_CONTAINEES);
super.lock();
But, Now my refresh button is not working as depend on the "Auto Refresh = True" to update the table.
Can anyone tell me how can I refresh the VO of my table from the button.
Thanks
Abhijeet.
P.S: I have already added the partial trigger but it is work not working as the data is cached in the VO. Removing the Cached property for the VO is creating other problems.
