How to update records marked by [row selector] ?

Hello,
I have a small table (PK=record_id) from which I send mail to a user of informational reasons. At the moment I can only send all records in a mail, but I want to be more 'selective', send only marked records.
The table is shown in a APEX-report defined as an updateable report.
I added a column [record selector] to it, allowing me to put a mark before the record to be send.
I did not succeed however sending the user only the marked records....
I tried something like
BEGIN
-- Loop through the rows that have been checked.
FOR I IN 1..HTMLDB_APPLICATION.G_F01.COUNT
LOOP
SELECT record_id
INTO to_be_send_record
FROM meldingen_voor_postverzending
where HTMLDB_APPLICATION.G_F01(I) = 'Y' ;
-- place the record with record_id = to_be_send_record
-- into a mail (via a self-made package) ...
END LOOP;
-- send the mail (using HTMLDB_MAIL)
END ;
It looks as if the records marked are not selected, but I can't find the reasopn why.
Maybe the = 'Y' is not correct, but I also tried "is not null" , '!= NULL" and other things.
Can anybody help me getting opnly the checked records into the mail-body?
Thanks and regard,
Jan.

Hi Jan,
try the following code:
DECLARE
   vRow BINARY_INTEGER;
BEGIN
   :p95_text := NULL;
   FOR i IN 1 .. apex_application.g_f01.COUNT
   LOOP
      vRow := apex_application.g_f01(i);
      :p95_text :=
            :p95_text
         || CHR (10)
         || vRow
         || '. '
         || apex_application.g_f02 (vRow)
         || ' / '
         || apex_application.g_f03 (vRow)
         || ' / '
         || apex_application.g_f04 (vRow)
         || ' / '
         || apex_application.g_f05 (vRow)
         || ' / '
         || apex_application.g_f06 (vRow)
         || ' / '
         || apex_application.g_f07 (vRow);
   END LOOP;
END;The APEX row selector returns the row number of the selected row. Not the primary key or whatsoever. So you have to use that value to access the arrays of the other columns.
Hope that helps

How to update record xml data?

Hi,
How can update existing record using an existing xml packet?
Thanks.

Hi,
The above Exception seems to be because of mapping error.
Check your mapping for all the mandatory 1-1 mapping, also the 1-unbounded parent node mapping.
Once when you import the XSD and activate your External Definition if it does without any error then there is no problem with your External Definition.
If this error occurs only when you test your mapping then this is mapping error and not because of XSD.
Please check the parent node mapping like 1-unbounded.

How to update records in a table based on user selection..

Hi all,
This time the above doubt is totally based on the logic of coding which I tried a lot but didn't get any solution. so atlast I come to sdn site.
please help..
The requirement is like that I have a table with 6 fields (1 primary key and other are nonkeys). If the user inputs some values in the fields on the screen, then a row will be added in the table. Upto this i have done well. but when the user want to change some value in the existing row of the table my program unable to do so. Because I couldn't get any logic to do that as there are 5 nonkey fields, so if any one field is modified then the respective row should be selected first based on the user selection and then it should be updated.
At this point I could not get any idea as it may take a lots of if conditions (I guess) to reach to that particular row.
Please help..
thanks ,
sekhar

Hi Sekhar,
I am afraid, the whole design of your program is wrong, let me explain
Let us say you have two rows(5 non key fields) that the user wants to update and the data in these five non key fields are identical and in your program you are getting a number(which is the key) using a number range object. So you will have two entries in the table for the same data.
And on the update page when the user enters the non key fields, how will the program know(or for that matter any one of us) which record to pick, if you have two identical books and if asked for a book wouldn't you ask which one among these two do you want?
Possible Solution: Identify a possible key maintaining the integrity of the data, that is a combination of the non key fields which will help you identify a unique row and make these fields as key fields in the table.
A more costly solution(if you do not want to change the non key field keys to key fields) would be to, adding a check(using select statement) to see if the non key fields combination already exists in the Z table before inserting a record into the table.
If yes, throw a message to the user and just update the values in the table, else insert the record.
Another solution would be to, use the non key fields to generate a key(using some logic) and using this instead of the number range object.

How to update Records of SAP table from .CSV file

Hi,
I have written a code which takes a data from (,) delimited CSV file and adds it into the Internal table.
Now I want to update the all fields in SAP table with the Internal table.
I want to use Update statement.
Update <table Name> SET <field needs to update> WHERE connditon.
I don't want to iterate through thousand on record in sap table to check the where condition.
Could you please tell me how to do it.

Hi. I thing you will not workaround the iterating of the internal table.
You can pre-load all the records into another internal table
check lt_csv[] is not initial. " important, otherwise next select would read all records of the table
select .... into lt_dbitab for all entries in lt_csv where key-fieds = lt_csv-key_fields...
check sy-subrc eq 0 and lt_dbitab[] is not initial.
then do in-memory update of the it_dbitab
loop at it_dbitab assign <fs>.
read table lt_csv assign <fs_csv> with key ... " lt_csv should be sorted table with key, or you should try to use binary search
if sy-subrc eq 0.
...change required lt_dbitab fields: <fs>-comp = <fs_csv>-comp...
endif.
endloop.
ant then you can do mass-update
update dbtab from table lt_dbitab.
From performance view, this solution should be much faster than iterating lt_csv directly and updating every single database record

Hi,
you record for an item and then click on page down and save it.use the loop on this bdc to populate the the bdc table no need to do manually.
LOOP AT l_i_dettab_item INTO l_wa_dettab_item..
      l_cursor = l_cursor + 1.
      IF l_cursor GT 1.
        PERFORM bdc_field       USING 'BDC_OKCODE'
                               '=P+'.
      ENDIF.
      PERFORM cursor_pos_notation    USING 'V_EAN_DET001- GTIN_VARIANT_TYP'

                                    CHANGING l_cursor_notation.
         PERFORM bdc_field       USING l_cursor_notation

                                    '=SAVE'.
    ENDLOOP.
Here my ok code for page down is =P+ so i am looping on the table control data and then populating the bdc table after this i will populate the remaing info required for the call transaction and refresh bdcdata.
thats it no need to do recording 1000 times.
now if u do like this it doesn't depend on the number of records on table control.
it will take all the records.

How to update Record Model for old Records(Personnel Record) in DPF?

Hi
i was able to successfully implement Digital Personnel files and Record Management for my scenario, but now question is:
i have created a record for personnel using "SE38--> Report (RPASRCREATEDPF)" or "Tx RPASRCREATEDPF) after a while i decided to add a node to my record model , how can i update my personnel records to new record model?
i need to do it for several staff and this is not logical to change record for every individual staff. Also when i deleted a record and recreated it all of old Archived and Processed Document gone.
Any Idea?
Regards,
Ali.

what is the easiest way for editing record
please guide me thanks

Hi ABDULLAH,
>> what is the easiest way for editing record
What do you mean by “editing record” ? Do you mean that you want to update the record according the textboxes in the form? If so, I am afraid that there is no better way, you need to use the ado.net and the update command to achieve that like you insert
new records. If you want to modify the record in the datagridview directly, I think you could bind the dataset to the datagridview, and then modify the record in the datagridview, and then save the changes to the database. The link below might be useful to
you:

How to Insert Record with multiple rows

Hello alls,
i want to ask something... how to use insert record server behavior - php myysql, to insert multiple rows from textfiled?
thanks.

It would have been more helpful if you had shown me your existing code. However, this shows the basic principles.
First of all, the name of each input field in the form needs to end in an empty pair of square brackets like this:
<input type="text" name="field_name[]" . . .
This results in $_POST['field_name'] being treated as an array of the values in each input field. Change field_name to the actual name of the input field. Without the square brackets, only the last value is submitted by the form.
The Insert Record server behavior code looks like this:
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$insertSQL = sprintf("INSERT INTO my_table (field1, field2) VALUES (%s, %s)",
                       GetSQLValueString($_POST['field1'], "int"),
                       GetSQLValueString($_POST['field2'], "text"));
mysql_select_db($database_connAdmin, $connAdmin);
$Result1 = mysql_query($insertSQL, $connAdmin) or die(mysql_error());
$insertGoTo = "another_page.php";
if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
header(sprintf("Location: %s", $insertGoTo));
You need to amend it like this:
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
mysql_select_db($database_connAdmin, $connAdmin);
// loop through the input values
for ($i = 0, $len = count($_POST['field1']); $i < $len; $i++) {
      $insertSQL = sprintf("INSERT INTO my_table (field1, field2) VALUES (%s, %s)",
                            GetSQLValueString($_POST['field1'][$i], "int"),
                            GetSQLValueString($_POST['field2'][$i], "text"));
      $Result1 = mysql_query($insertSQL, $connAdmin) or die(mysql_error());
} // end loop
$insertGoTo = "another_page.php";
if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
header(sprintf("Location: %s", $insertGoTo));
This uses a for loop (see http://docs.php.net/manual/en/control-structures.for.php) to access each element of the $_POST['field1'] and $_POST['field2'] arrays (see http://docs.php.net/manual/en/language.types.array.php).

[Solved] How to update records in entity based on view with distinct

Hi
- I have a relational view of the form:
SELECT DISTINCT
FROM TAB1, TAB2, ...- I created instead of triggers for delete, update and insert.
- I created an entity object on this and an updatable view object
- I added this to my module.
- Then I test the view object in the module (module > test), and if I try to update an existing record, I receive the error:
(java.sql.SQLException) ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc.
So, ADF internally create as select FOR UPDATE cursor to update the modified record and as the error shows, this is not possible on a view with distinct, ...
Is there a way to work around this error without to rewrite the view?
I was thinking that there is maybe a way to force ADF not to use the select FOR UPDATE and use UPDATE .. SET <value> WHERE <pk>, or maybe to create a new instead of trigger to catch the select FOR UPDATE?

Arti,
Here's another solution (that will still use locking, and can help avoid the "lost update" problem):

Any thoughts?
Thanks.

How to add a row-selector to an existing SQL Query (updatable report)

Hi,
I screwed up an extensive updatable report in Apex 4.2 region by one time indicating the page may be parsed at run time.
After setting this back (to validate query) a lot of the columns setting were gone, and also the row-selector
I actually don't kno how to simply add this row-selector back into place.
Anyone who can point me in the right direction?
Thanks a lot
Wim

Anyone who can point me in the right direction?Have you been able to recover all your other configuration and this is the last thing you need to fix? Or are all those other things needing to be fixed as well?
The reason I ask is that you may want to consider just starting from scratch, if you haven't put lots of effort into recovering everything else just yet.
On the other hand, if you just want to add a checkbox back into the SQL statement then you can add this, substituting your column name for empno of course:
APEX_ITEM.CHECKBOX2(1,empno,'CHECKED') "Select"When you do this you'll get a warning that you're changing the interactive report, which you should accept. Then you need to make sure that the column is actually shown in the interactive report by making sure it's in the displayed columns list. And you may also need to change the display type of the column to "Standard Report Column"
Hope that helps.

SQL Query updateable report with row selector. Update process.

I have a SQL Query updateable report with the row selector(s).
How would I identify the row selector in an update process on the page.
I would like to update certain columns to a value of a select box on the page.
Using the basic:
UPDATE table_name
SET column1=value
WHERE some_column=some_value
I would need to do:
UPDATE table_name
SET column1= :P1_select
WHERE [row selector] = ?
Now sure how to identify the [row selector] and/or validate it is checked.
Thanks,
Bob

I don't have the apex_application.g_f01(i) referenced in the page source...In the page source you wouldn't find anything by that name
Identify the tabular form's checkbox column in the page(firebug/chrome developer panel makes this easy)
It should be like
<input id="..." value="" type="checkbox" name="fXX" >we are interested in the name attribute , get that number (between 01 and 50)
Replace that number in the code, for instance if it was f05 , the code would use
apex_application.g_f05
--i'th checked record' primary keyWhen you loop through a checkbox array, it only contains the rows which are checked and it is common practice to returns the record's primary key as the value of the checkbox(available as the the i'th array index as apex_application.g_f05(i) , where i is sequence position of the checked row) so that you can identify the record.

How to update records marked by [row selector] ?
