Executions/Rows Processed in statpack

I'm looking at insert statement in the "SQL ordered by Executions" section of the statpack. I have Executions = 400,626 and Rows Processed = 400,464.
Does this mean that the aplication actually issued 400,626 inserts but only 400,464 were really inserted?
Thanks a lot,mj

This means that some of the insert failed for some reasons - like duplicating of PK,Check constraints... The problem I'm having is the missing rows in the Log/audit table which should never happen and I need to discover what exactly is missing. The application obviously ignores the errors. How can I find what inserts are failing and why? Trace which level?
I also have another insert statement with more row processed then executions. Does this mean that there have been some inserts with multiple rows at the time? Can we rely on this numbers 100%?
Thanks lot.mj

Insert number of executions vs rows processed

I'm reviewing a conventional load job that was running in my environment and I came across something that I couldn't explain correctly and was hoping for some help. Say I run an AWR report and look at a particular insert statement in the section "SQL ordered by Executions" and I look at the column "Rows per Exec" I would expect this to be one so that each row inserted increments the counter for exections of the same sql statement. How does oracle processes rows per each execution of the same insert statement? Like I said I initially thought each row would be an execution. Below is an example from and AWR report, the sql was edited by me before posting.
Executions Rows Processed Rows per Exec Elapsed Time (s) %CPU %IO SQL Id SQL Module SQL Text
33,021,240 396,254,880 12.00 18,317.08 65.80 0.55 7v0u50ct2tfyn pmdtm@server123 (TNS V1-V3) INSERT INTO TABLE1(ID, NAME, DATE) VALUES ( :1, :2, :3)

Even though statement such as “INSERT INTO TABLE1(ID, NAME, DATE) VALUES ( :1, :2, :3)” implies one-row-at-time execution, some drivers (JDBC and others) implement bulk processing for this type of insert. Please check the settings of your driver and, if possible, the actual code that issues the insert.

Are 'read only' items causing my automatic row processing to fail?

I have a form that uses automatic row processing to update my table.
I recently had to add a check to lock down the fields using the read only condition where a record has been 'approved'. So, I turned off all of the fields and hid the update button.
Now they want me to check to see if the user is a manager, and if so, allow them to see the update button, and make a single field on the form modifiable.
I have the user identified as a manager, and can make the field accept the change (a yes/no combo box). Yet when they click the update button, the form just sits there. A branch is supposed to fire on hitting that button, taking them back to the previous report, but it doesn't happen. The source of the combo box in question uses a column on the table, and works fine when the form has all of the fields showing for modification.
I had some validations that I finally set to never fire, thinking that they were failing and just not giving the error messages. I know a bad sql or pl/sql atatement in a validation will cause the form to just keep sitting there doing nothing, and thought it might help.
Several of the various fields are combo boxes, several are text boxes.
I'm stumped.
Shall I keep the regular update button hidden whether it is a manager or not (because it has been 'approved'), and enable a new button that fires off a process to update the one field that the manager may want to change? Does making a field 'read only' always have a detrimental effect on the auto processes I've been counting on? Is that if fact what is happening now?
Thanks in advance for any advice or comments on this.

Hi, Scott.
My version is 3.0.0.00.20
I have received info to set up the application, though I have not activated it as yet. I'm reluctant to try to load up the various tables to make it work. It could be done.
My workaround is to that the user (a manager) fires off to another form to show an individual record, and ask if he/she really wants to make this change. On submit, they will be taken back to the original locked down form, and I will update the single field in that process of returning them. This will actually be a plus, in that I expect to show them all of the 'duplicate' entries for that item, and show them that by 'activating' this particular item, they will 'deactivate' the one duplicate that is currently active. Or, if they are deactivating the sole item that is active, that there will in fact be no active items in the system. Convoluted as heck, but they swear this is how they've been doing business with their briefcases and file cabinets of Excel files. I'm surprise they even float at this point (these are ships we're talking about).
This all may be due to the form originally having a next/previous/count process once arrived at my clicking on the edit button of the report of items. All of that has been hidden away, and though the fields exist of the form, they are not used. They only see the current item that they clicked on from the report.
I read up a little on session state, as well as posts with the debug error I was getting. I'm still not on board with the whole issue of 'state'. Items stay as they are until they're changed, no? I suppose that sounds simplistic.
One of the things that caught my eye was several combo box lists that on read only mode, showed [] square brackets. Which, in some cases is okay.
What I'll try to do is set up a public application - for future use if nothing else. I'm going to be working on this for awhile. I have more than a bit of work to do to cleanse the data as well as get rid of the single sign on requirement (I'll assume that I should have to do this) in order to share the app.
I know you're expecting me to have this up and running for you to look at, but I'm under the gun. And they actually like my workaround.
I'll keep everybody informed, one way or another.

Processing Static (via automatic row processing) & Dynmaic fields

Hi,
I have a page that has 2 sections. Section S is statically driven which I'd like to process via a Automatic Row Process DML. Section D is for dynamic fields which I process via a PL/SQL script.
I need to process Section D (dynamic) first.
Now they're 2 things that I'm noticing when I try this. Can someone please confirm.
- After my process of Section D it seems to make a commit. I know this since I have a error in Section S, and the values from Section D are committed to the DB. I need to make sure a commit only occurs after all page processes have completed error free.
- My Automatic Row Process DML for Section S doesn't seem to work at all. It can't seem to read the values at all. I know this since I have several columns which are "NOT NULL" and the appropriate error messages are being raised. The Automatic Row Fetch for Section S does work properly.
For the time being the work around is writing a process for the entire page which includes both Section S and Section D. The thing is I thought that HTMLDB would be able to help me out a lot with Section S since it had static fields etc.

Martin - I would try to debug these two processes separately. If the Auto DML process isn't firing, perhaps the button used to submit the page isn't setting the request to one of the standard values recognized by the Auto DML package ('INSERT','CREATE','CREATE_AGAIN','CREATEAGAIN' for inserts and 'SAVE','APPLY CHANGES','UPDATE','UPDATE ROW','CHANGE','APPLY' or like 'APPLY%CHANGES%' for update).
A commit happens whenever session state is changed, so if your process saves an item value, that would do it. If you think that is not the cause of the commit, let me know the details of the process and I'll take a closer look. There is no way to prevent the commit when session state is updated.

Without Automatic Row Processing (DML)

Hi All
I try to make one page to show use DML statements without standard Automatic Row Process.
What I have:
One page with:
region: Report - select empno, ename, sal, deptno from emp;
region: Form with items: p6_empn, p6_ename, p6_sal, p6_deptno
addictionaly in that moment I have:
process CreateProcess:
begin
insert into emp (empno, ename, sal, deptno)
values (emp_seq.nextval, :P6_ENAME, :P6_SAL, :P6_DEPTNO);
commit;
end;
and button CREATE.
Create Process is fired when I push CREATE button and Insert statement works corecctly. Branch is on the same page. (I use request).
Now I would like to show update and delete statements.
In Report I have in column EMPNO standard button Edit (each row)
(<img src="#IMAGE_PREFIX#edit.gif" alt="Edit">)
I have process SelectProcess:
begin
select ename,sal,deptno
into :p6_ename, :p6_sal, :p6_deptno
from emp
where empno = :p6_empno;
end;
It is fired In Load _ Before Header
When I push Edit in one row I would like to see details of employee in Form, but I see nothing. In session state all is correct - I see :p6.... with name, sal and ...
I dont know how to connect this process with buton and branch.
could you help me?

Hi,
I have done a quick test for this - [http://htmldb.oracle.com/pls/otn/f?p=25946:1]
On the Edit page, I have a process called P2_LOAD_DATA that runs "On Load - Before Header", is conditional on P2_EMPNO being NOT NULL and using the following code:
BEGIN
SELECT EMPNO, ENAME, JOB
INTO :P2_EMPNO, :P2_ENAME, :P2_JOB
FROM EMP
WHERE EMPNO = :P2_EMPNO;
END;I have a button with a Button Name setting of "UPDATE" (user sees this as Apply Changes)
I then have a process that runs "On Submit - After Computations and Validations" and is conditional on REQUEST = UPDATE. The code is:
BEGIN
UPDATE EMP
SET ENAME = :P2_ENAME,
JOB = :P2_JOB
WHERE EMPNO = :P2_EMPNO;
END;The source settings on P2_EMPNO, P2_ENAME and P2_JOB are as I described in my previous post.
One thing to check - do you have a "reset page" process? If so, remove it.

Hi Manisha,
You can create the Message alert for process chain as follows.
     1. Goto change mode of Process Chain
     2. Right click on the particular Process step/Process chain and choose Create Message.
     3. Choose the Actions (Sucessful / Failure/Always) for which you want to aler the users
     4. Choose the New variant and define the Variant Name and Message header and enter
     5. Create the message and the save the variant and activate the process chain.
Once you triggere the process chain, according the message typr, the users will be alerted.

Adding a new field to an Automatic Row Processing form

Hi,
I have a form that I built through the form Wizard which has an automatic row processing function. It is working very well, except that any new fields I add to the form are not being updated in the database when the row is processed. I have set up the field exactly the same as other fields which are working and were originaly created by the wizard. I have deleted and recreated the row processing Page Process, but nothing seems to make it work. Have I missed anything? I don't want to recreate my page from scratch each time I want to add a new field.
Thanks,
Steve

if you're positive that your new fields/columns update correctly when you use Text Field items and not when you use Select List ones, i'd check to see what your select lists are returning. a good way to see exactly what your form got from your select list items is to check the session state for your select list items right after you submit your page (clicking the "Session" link in your developer toolbar in your runtime environment is a good way to get to this info). also, even though you said your added Text Fields work and your Select Lists don't, i'd still check the "Source Type" and "Source value or expression" fields of your select list items to make sure they're set correctly. for form items to work with your table in htmldb auto-dml processing, you need to set the "Source Type" to "Database Column" and the "Source value or expression" to the case-sensitive name of your db column.
hope this helps,

BLOB column not updating using automated row processing

I have fiddled around with creating a simple application to understand how APEX handles images stored in blobs - did a simple app that stores them, gets them, displays them. it all works great.
so i have this existing table/application that i am trying to add a BLOB column to here's what i did:
it's a pretty simple form on a table with report application. just one table.
I added the BLOB to the table (and the other mimetype etc cols as well).
i added the page items to the form page.
i basically made everything identical in terms of page item settings and such to the working simple application.
so here's the problem... when i run the application and update a row, the BLOB column isn't updating. neither are the mimetype or filename columns. the activity date col is.
and here's another interesting thing. i quickly created another form and report pair on the same table, and when i ran it, it updates the blob col just fine.
why is my original form not updating it? what can i do to remedy this? any ideas? i've gone though setting by setting for the blob page item and the one that works is identical to the one that doesn't.
i'm using the automatic row processing to update the table.

Unable to set default date for Date Picker item using Auto Row Processing

Okay, I have searched through the forum for an answer, and have not found a thing to account for my problem.
First, does anyone know if using Auto Row Processing has problems updating an item/field in a record where the Source is defined as Database Column if the 'Display As' is defined as 'Date Picker (MM/DD/YYYY)'?
I ask this only because I found out the hard way that Auto Row Processing does NOT fetch the value for an item where the field is defined as TIMESTAMP in the database.
My problem is as follows: I have a form that will CREATE a new record, allowing the user to select dates from Date Pickers, text from Select Lists, and entering in text into a Textarea item. The information is saved using a standard (created through the Auto Row Processing wizared) CREATE page level button. After the record is created the user is able to go into it and update the information. At that time, or later, they will click on one of two buttons, 'ACCEPT' or 'DECLINE'. These are Item level buttons, which set the REQUEST value to 'APPLY' (Accept) and 'UPDATE' (Decline). The Accept button executes a Process that changes the Status Code from 'Initiated' to 'Accepted', and sets the Declined_Accepted_Date to SYSDATE, then another Process SAVEs the record. The Declined button runs a Process that changes the Status Code from 'Initiated' to 'Declined', and sets the Declined_Accepted_Date to SYSDATE, then another Process SAVEs the record.
However, even though the Status Code field is updated in the database record in both Accepted and Declined processing, the Declined_Accepted_Date field remains NULL in the database record (by looking at the records via SQL Developer). WHY??? I looked at the Session State values for both the Status Code and the Declined_Accepted_Date fields and saw that the fields (items) had the expected values after the process that SAVEs the record.
The following is the code from the Accept button Page Process Source/Process:
BEGIN
:P205_STATUS_CD := 'A';
:P205_REF_DECLINE_ACCEPT_DT := SYSDATE;
END;
As can be seen, the Status Code and Declined_Accepted_Date items are set one right after the other.
As an aside, just what is the difference between Temporary Session State vs Permanent Session State? And what is the sequence of events to differentiate the two?

Here's yet another thing that I just looked into, further information...
One other difference between the date field I am having problems with (Accepted_Declined_Date), and other dates (with Date Pickers) in the record is that the Accepted_Declined_Date never gets displayed until after it is set with a default date when the Accept and Decline buttons are pressed.
One of the other dates that works, the Received Date, is able to write a default date to the record that is never typed into the box or selected from the calendar. That date is placed into the box via a Post Calculation Computation in the Source, which I set up as: NVL(:P205_REF_RECEIVED_DT,TO_CHAR(SYSDATE,'MM/DD/YYYY'))
However, I do remember actually trying this also with the Accepted_Declined_Date, and setting the Post Calculation Computation did not work for the Accept_Decline_Date. Could this be because the Accept_Decline_Date is never rendered until the Status Code is set to Declined (in other words, there is no need to display the date and allow the user to change it until the record is actually declined)???
The control of the displaying (rendering) of the date is set via the Conditions / Condition Type: Value of Item in Expression 1 = Expression 2
Expression 1 = P205_STATUS_CD and Expression 2 = L
Does this shed any light???

Solved: Delete Using Automatic Row Processing

See Scott's reply below for the answer.
Hi there,
I have an application built in APEX 3.0.1 that I would like to be able to use a button to delete a single row from an underlying database table (owned by the parsing schema).
My APEX page has a 3 HTML regions on it:
1. Only a Select List and Go button for User selection (of Debit Note)
2. Ten display Items (Text Field, Disabled saves state) displaying further information about User selection
3. Conditional Delete button (region with custom image) - only displays when P73_DEBITNOTEID is NOT NULL
I'd like this button to be used to Delete the Selected Item and thought I'd be able to use a Data Manipulation Page Process - Automatic Row Processing (DML) page process to do this.
However, when I go through the wizard the Select item containing primary key column value field has no values in the search list.
My first question is why was there no values in the list?
So I manually entered the Item I required (P73_DEBITNOTEID) but when I run the page and click the button I get a PL/SQL missing expression error.
What is the best practice method to do DML actions on the underlying database tables. The tables are all owned by the parsing schema.
Your help in resolving this matter would be greatly appreciated.
Kind Regards,
Gary.

Understanding "automatic row processing"

hi,
i have problems understanding automatic row processing in apex.
at first i thought there is a relation between page process (fetch row, insert, update,...) and page items / reports.
something like: Item P1_TESTTEXTBOX (Source=Database Column => "TESTCOLUMN") referes to process "FETCH ROW FROM TESTTABLE"
but i havent found any relation.
then i thought there is a "global pool of database columns" (fetched, inserted, updated by a page processes)... when a fetch process loads data from a db-table, all columns from this table are stored in a "dictionary"...but this also didnt seems to be right.
i did some testing to understand the (row fetch) behavior but there a still some questions:
- i created 2 Processes (Data Manipulation -> Row Fetch) in "After Header" on 2 different Database tables but each with a Column "TESTCOLUMN" (for testing^^) . It didn't work properly: it seems that only one fetch process is executed .
I'm still not quite sure how automatic row processing (fetch, insert, update) is working...
are there any explanation about this issue? i havent found any information that goes into detail.

ok, some testing later i come to the conclusion that the automatic row processing works like this:
when a row (fetch) process starts, ALL binded Page Items (Source Type=Database Column) tries to load their data from the current fetch-process.
i tried to add 2 different Regions containing some Page Items (TextBox) that binds to a Database Column.
* Region1 should contain Artikle-Information (refers to DB-Table Article)
* Region2 should contain Article-Detail Informations (refers to DB-Table ArticleDetails)
i am not able to create 2 Row fetch processes in 1 page, because i got an error when the first row-fetch process starts "Column [XY] not found in table [YZ]"
obviously there is no way to "link" processes to regions, reports or page items.
or is it possible to create 2 regions (in 1 page) with automated row processing, that refers to different tables ? (region1/report1 => DBTable1, region2/report2 => DBTable2)?
(the only way i see is that i create a view that contains these 2 DBTables, so i only need one row fetch process for this page)
thanks in advance

Automatic row processing insert fail

Hi all,
Application Express 3.2.1.00.11
Oracle Database 10g Release 10.2.0.3.0 - 64bit Production
I am running into a problem where my automatic row processing will update and delete records but will not insert. I get the following error.
ORA-44003: invalid SQL nameI disabled all triggers and added the appropriate fields to my form and manually entered correct data and am still having the issue. I can run a trace but only the dba has access to retrieve the file and he is gone. Any suggestions on where to start? i checked debug mode and it is definitely hanging on the ARP.
Cheers,
Tyson Jouglet

All,
Finally fixed it!!! So if you experience this problem, double check all of your item sources. I was upgrading a date column to a timezone column and subsecuently made it three different items. Long story less long, I left the original date item on the form and deleted the source column name but i forgot to change the item source from database column to something else. This will not effect how apex deletes or updates a record but it will not allow you to insert a new record. I know this is a user error, but maybe this could be added as a validation?
Cheers,

Automatic Row Processing - Preset a value with value from other page

Hi everybody,
I have created a form on a table with report. I added a dropdown field to a sidebar region on the first page the groups and selects only a couple of these entries. (Think: only people for the department selected in the drop down field). Now when I click on the normal create button the id field for the department should be filled automatically with the value from the page before, where something was already selected in the drop down field. The id field is a hidden field on the actual create page. Maybe it is not working because the field is linked to the database column to make the automatic row processing work or something. I tried computions on both pages and setting the values. Nothing seems to do the trick.
Any help would be greatly appreciated.
Thanks,
Henrik

Hi,
these are the values I currently see:
108 14 P14_SELECTEDSS Display as Text (escape special characters, does not save state) No
108 14 P14_CHARACTERISTIC_ID Hidden and Protected Reset to Null No
108 14 P14_SHAREDSERVICE_ID Text Field 30 Inserted No
108 14 P14_CAPTION Text Field No
108 14 P14_CATEGORY_ID Select List No
108 14 P14_WEIGHING Text Field No
108 14 P14_DESCRIPTION Textarea No
I also have to say that I deleted the computations I created earlier again cause they did not work and I had the same values for these variables. I am trying to (pre)set P14_SHAREDSEVICE_ID to P13_SELSS when I click the create button on page 13.
Thanks again,
Henrik

Automatic Row Processing (DML) process is not updating the record

Hi all,
I have an application which was working fine last week and tested and backuped to new application. This Monday, one of the form in that application is not updating the data all of a sudden. I debug that by having page 0 variable and assign the value from the column variable to page 0 variable. Whatever value I changed to the column variable was getting updated to page 0 variable. But it is not updated in the database. So, I changed the success message of the "Automatic Row Processing (DML) process" and I can see the success message on the page, but the column value does not get updated. But when I go back and checked my backup application, that page is working fine. For now, I copy that from the backup application, but I would like to know why this is happening?
Thanks
SHY

Hi Scott,
Thank you very much for your response. Because of the database complexity, I can't create/import the application on the apex.oracle.com. I am just wondering why this is happening. One of my coworker said same thing happened to her in one of her project and it gets resolved once she restart the server. I am not able to restart the server to check and see if this resolved as the application is on the client server. Do we need to clean up any log file? Thanks.
