Unique constraint violation - Finding inserted row before commit

Hi,
I have a scenario something like that, where I need to insert a row to a table - contact, for different employees under different department. So I happen to insert same employee contact multiple times & do commit at the last if there is no contact in the table. How to find out if the same employee record is already inserted ?.
The unique constraints is on emp id + depatment id in the contact table. So I face the issue when i do the commit, it finds the same emp id + dept id contact has been inserted multiple times.
Please let me know how to handle it?
Regards,
Dhamo.

Hi
What is exactly what you want to achieve? Do you want to display a message to the user? Do you want to prevent it to post the contact if it already exists?

Element-by-element multiplication of a vector with matrix rows

I want to element-by-element multiply a Vector with the rows of a Matrix ,in the most efficient way. Anybody knows if there is a sub vi for this in LW7.0 ?
(The Inputs are a Matrix; and a Vector with the same size as Matrix's # of columns ; the output is a Matrix with the same dimension as input Matrix. Every row of the output Matrix is the product of element-by-element multiplication of input vector with the correspondind input Matrix's row )
Thanks

(Yes, the 2D linear evaluation is basically the same as the 1D evaluation except for the dimension if the array. NI could merge them into one and make the array input polymorphic with respect to size. )
I "think" you want a plain multiply (not a polynomial evaluation). You can do it (A) one row at a time or (B) one column at a time, but A might possibly be slightly more efficient. Do all three (including the one in the next message) and race them with your real data! Message Edited by altenbach on 03-14-2005 07:47 AM

Add Row Before Or After Selected Row In af:Table

Hi,
Please let me know how can we add a row either before or after the selected row in the af:table.
Currently i have a table with 2 toolbar buttons. 1.Add Before 2.Add After.
User selects the row and clicks either AddBefore/After button ... then, an empty row should get added in the table as per the button clicked.
Please suggest me your inputs.
Thanks,

How to write multi row sub query with the row containing range of values?

Hi all,
I have to include a column which contains weight ranges and it should come fom table called "report_range_parameters"
The following query will reutrn those weight ranges.
select report_parameter_min_value || ' -> ' || report_parameter_max_value
          from report_range_parameters
         WHERE report_range_parameters.report_parameter_id = 2359
           and report_range_parameters.report_parameter_group = 'GVW_GROUP'
           and report_range_parameters.report_parameter_name = 'GVW_NAME'
                    The below query should return the values group by those weight ranges.
How could I write that sub query?
select   SUM(NVL("Class 0", 0)) "Class 0" ,
            SUM(NVL("Class 1", 0)) "Class 1" ,
            SUM(NVL("Class 2", 0)) "Class 2" ,
            SUM(NVL(" ", 0)) "Total"
     FROM (
             SELECT report_data.bin_start_date_time start_date_time,
                    SUM(DECODE(report_data.gvw, 0, report_data.gvw_count, 0)) "Class 0" ,
                    SUM(DECODE(report_data.gvw, 1, report_data.gvw_count, 0)) "Class 1" ,
                    SUM(DECODE(report_data.gvw, 2, report_data.gvw_count, 0)) "Class 2" ,
                    SUM(NVL(report_data.gvw_count, 0)) " "
              FROM report_data
             GROUP BY report_data.bin_start_date_time
          ) results
   RIGHT OUTER JOIN tmp_bin_periods
                 ON results.start_date_time >= tmp_bin_periods.bin_start_date_time
                AND results.start_date_time < tmp_bin_periods.bin_end_date_time
           GROUP BY tmp_bin_periods.bin_start_date_time,
                    tmp_bin_periods.bin_end_date_time Thanks.

Hi,
Assuming the following 4 things:
(1) report_range_parameters contains data like this, from your [previous thread|http://forums.oracle.com/forums/message.jspa?messageID=3541079#3541079]
id group      name         min_value      max_value
1   gvw_group gvw_name      0              5
2   gvw_group gvw_name      5              10
3   gvw_group gvw_name     10              15(2) max_value is actually outside the range (that is, a value of exactly 5.000 is counted in the '5->10' range, not the '0->5' range)
(3) the range has to match some column x that is in one of the tables in your main query
(4) You want to add that column x to the GROUP BY clause
then you shopuld do somehting like this:
select   SUM(NVL("Class 0", 0)) "Class 0" ,
            SUM(NVL("Class 1", 0)) "Class 1" ,
            SUM(NVL("Class 2", 0)) "Class 2" ,
            SUM(NVL(" ", 0)) "Total"

     FROM (
             SELECT report_data.bin_start_date_time start_date_time,

                    SUM(DECODE(report_data.gvw, 1, report_data.gvw_count, 0)) "Class 1" ,
                    SUM(DECODE(report_data.gvw, 2, report_data.gvw_count, 0)) "Class 2" ,
                    SUM(NVL(report_data.gvw_count, 0)) " "
              FROM report_data
             GROUP BY report_data.bin_start_date_time
          ) results

Let's say for example user have to the use the form to enter all 10 items or few like 5 on their stock form into 4 different textbox field each lines of your form, however these items go into a "Stock_table" under Single insert transaction query when submit button is pressed.
Please anyone help me out, on how to get this concept started.

Hello,
I have a way to do this, but it would take some hand coding on your part. If you feel comfortable hand writing php code and doing manual database calls, specificaly database INSERT calls you should be fine.
Create a custom form using the ADDT Custom Form Wizard that has all the rows and fields you need. This may take a bit if you are adding the ability for up to 20 rows, as per your diagram of the form area. The nice thing about using ADDT to create the form is that you can setup the form validation at the same time. Leave the last step in the Custom Form Wizard blank. You can add a custom database call here, but I would leave it blank.
Next, under ADDT's Forms Server Behaviors, select Custom Trigger. At the Basic tab, you enter your custom php code that will be executed. Here you are going to want to put your code that will check if a value has been entered in the form and then do a database INSERT operation on the Stock_table with that row. The advanced tab lets you set the order of operations and the name of the Custom Trigger. By default, it is set to AFTER. This means that the Custom Trigger will get executed AFTER the form data is processed by the Custom Form Transaction.
I usually just enter TEST into the "Basic" tab of the Custom Trigger. Then set my order of operations in the "Advanced" tab and close the Custom Trigger. Then I go to the code view for that page in Dreamweaver and find the Custom Trigger function and edit the code manually. It's much easier this way because the Custom Trigger wizard does not show you formatting on the code, and you don't have to keep opening the Wizard to edit and test your code.
Your going to have to have the Custom Trigger fuction do a test on the submitted form data. If data is present, then INSERT into database. Here's a basic example of what you need to do:
In your code view, the Custom Trigger will look something like this:
function Trigger_Custom(&$tNG) {
if($tNG->getColumnValue("Item_1")) {
$item1 = $tNG->getColumnValue("Item_1");
$textbox1_1 = $tNG->getColumnValue("Textbox_1");
$textbox1_2 = $tNG->getColumnValue("Textbox_2");
$textbox1_3 = $tNG->getColumnValue("Textbox_3");
$date1 = $tNG->getColumnValue("Textbox_3");
$queryAdd = "INSERT INTO Stock_table
(item, Qty_In, Qty_Out, Balance, Date) VALUES($item1, $textbox1_1, $textbox1_2, $textbox1_3, $date1)"
$result = mysql_query($queryAdd) or die(mysql_error());
This code checks to see if the form input field named Item_1 is set. If so, then get the rest of the values for the first item and insert them into the database. You would need to do this for each row in your form. So the if you let the customer add 20 rows, you would need to check 20 times to see if the data is there or write the code so that it stops once it encounters an empty Item field. To exit a Custom Trigger, you can return NULL; and it will jump out of the function. You can also throw custom error message out of triggers, but this post is already way to long to get into that.
$tNG->getColumnValue("Item_1") is used to retrieve the value that was set by the form input field named Item_1. This field is named by the Custom Form Wizard when you create your form. You can see what all the input filed names are by looking in the code view for something like:
// Add columns
$customTransaction->addColumn("Item_1", "STRING_TYPE", "POST", "Item_1");
There will be one for each field you created with the Custom Form Wizard.
Unfortunately, I don't have an easy way to do what you need. Maybe there is a way, but since none of the experts have responded, I thought I would point you in a direction. You should read all you can about Custom Triggers in the ADDT documentation/help pdf to give you more detailed information about how Custom Triggers work.
Hope this helps.

Could i display data in VO before commit and re-query?

I have inserted some rows into ViewObject.i will display these rows before commit them.
The vo will be a temporary table.
how can i do it ? thanks ,best regards.

thanks . i have an idea.
first ,create a row ,and then insert this row.

Row: can't delete, can't hide, can't add row above, can't add row below

My row has no options! None on the drop down at far left of row, nor on the Table drop-down menu at top of Numbers.
What happened to my row? What happened to my table? I'm going nuts...I can't add more rows to my table.
Anyone know why this might be happening? Thanks in advance.

Is this a problem with only one row of a multi-row table or with every row of the table? Can you enter data into the table? Are the row numbers and column letters visible or are there x's at the corners of the table (indicating the table is locked)?

Trying to set the entity attributes in before commit and get the following

i get the following error when i try to set the entity attributes before commit.
JBO-28202: Entities invalidated in beforeCommit(). Need to re-validate and post.
can somebody let me know, how to re-validate and post.

I Suggest you set its Attribute on EOImpl, override doDML, and before call super.doDML set your Attribute. There is a special reason to set Attribute on beforeCommit?
Best Regards

Insert multiple rows with autoincrement id

I need to insert multiple rows to a table which has an autoincrement PK (unique), e.g:
Entity:
public Class Entity{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
Private Long id;
Facade:
@PersistenceContext(unitName = "xx-enterprise-ejbPU")
protected EntityManager em;
public void create(Entity entity) {
em.persist(entity);
Service Class:
public Class Service implements ServiceLocal{
@EJB
private XxxFacadeLocal xxxFacade;
public void saveEntity(Entity entity){
xxxFacade.create(entity)
ManageBean:
public Class ManageBean
@EJB
private ServiceLocal service;
public void doSave(ActionEvent event)
service.saveEntity(entity1); //entity.id is set to null, suppose to be generated by DB auto_increment, i.e. insert 3 rows with 3 different ids
service.saveEntity(entity2);
service.saveEntity(entity3);
The result is: Key duplication error on inserting entity2, but entity1 is inserted into DB with id auto increased correctly.
If I insert only one row each time for test purpose, everything works as expected.
But what I need is to insert multiple rows. How to do it?
Thank you in advance.

Like this (although the @Basic annotation is very much unnecessary). So if it isn't happening you must have made a mistake somewhere. Are you sure the ID column actually has auto_increment?
Also if you are using Hibernate as the persistence provider and you put it on the classpath, check the packages of the annotations you are using; Hibernate and JPA share some with the same name unfortunately.

Inserting multiple rows with single insert statement ?

Hi ,,
Consider a PL/SQL procedure.
I want to pass an array of values and insert in a table with a single statement.
Moreover I want to call this procedure to insert multiple rows from OCI program.
Can some body help ? :(
Thanks
Chandu

Hi Vincent,
Regular array insert which you have mentioned works in case of insert statement(This is to eliminate multiple calls to server)
Will it work for passing array to Stored procedure, in this case procedure will be called only once with an array.
It will be of great help if you give an example.
Thanks
Chandra

Fill multi row before insert

hello guys I want to fill a block with multiple rows before inserting the rows data are from 2 blocks in the form I tried to use next_record , down but they are all restricted here an example of what I want to do
I have block1 , block2 and block3 and I want to fill block3 with the first row of each block before inserting the data in the block3
what should I do?
Thanks in advance guys

But MRU and MRD.... where is Multi-Row Insert?
The MRU process does an update for existing rows and insert for new rows (that were added using the Add Row button)
I was thinking about adding an extra value and adding a trigger to do the inserting instead
Yes, a row-level trigger on the underlying table would be the best way to approach this problem. Let the APEX MRU and MRD processes do their job and your row-level trigger can keep inserting rows into a separate audit/history table with structure identical to the main table (plus sequence generated version number).
Something like
create table mytable_hist as select 'U' dml_action, 1 version_no,a.* from mytable a where 1=2;
create or replace trigger mytrig
after insert or update or delete on mytable
for each row
declare
l_action varchar2(1);
begin
if inserting then l_action := 'I';
elsif updating then l_action := 'U';
elsif deleting then l_action := 'D';
end if;
insert into mytable_hist
values
l_action,
version_no_seq.nextval,
nvl(:new.col1,:old.col1),
nvl(:new.col2,:old.col2),
nvl(:new.col3,:old.col3),
end;
