Select All in large table

My product has some very large tables (using RANGE_PAGING). I want to allow the end user to do a Select All operation, and then press a command button to act on all selected rows, but want my backing code to detect a Select All has been done, rather than attempt to retrieve all rows from the table. Is this doable with a RichTable?
I'm porting an existing UI over to ADF -- the old UI handled this by having a separate select all button (column header), which would get unset if any row got unselected, and the backing code could interrogate that. I was wondering if there was a more ADF-ish way of handling this.
Using Oracle JDeveloper 11g Release 1 (11.1.1.6.0)

(added JDeveloper version info)

Are you really using 11.1.1.6? If so, I guess you should be asking in one of the internal Oracle forums.
But, no, there's no "more ADF-ish" way to my knowledge :)

SELECTing from a large table vs small table

I posted a question few months back about teh comparison between INSERTing to a large table vs small table ( fewer number of rows ), in terms of time taken.
The general consensus seemed to be that it would be teh same, except for teh time taken to update the index ( which will be negligible ).
1. But now, following teh same logic, I m confused why SELECTINg from a large table should be more time taking ("expensive" ) than SELECTing from a small table.
( SELECTing using an index )
My understanding of how Oracle works internally is this :
It will first locate the ROWID from teh B-Tree that stores the index.
( This operation is O(log N ) based on B-Tree )
ROWID essentially contains teh file pointer offset of teh location of the data in teh disk.
And Oracle simply reads teh data from teh location it deduced from ROWID.
But then the only variable I see is searching teh B-Tree, which should take O(log N ) time for comparison ( N - number of rows )
Am I correct above.
2. Also I read that tables are partitioned for performance reasons. I read about various partiotion mechanisms. But cannot figure out how it can result in performance improvement.
Can somebody please help

Can somebody please helpIt's not going to be that simple. Before your first step (locate ROWID from index), it will first evaluate various access plans - potentially thousands of them - and choose the one that it thinks will be best. This evaluation will be based on the number of rows it anticipates having to retrieve, whether or not all of the requested data can be retrived from the index alone (without even going to the data segment), etc. etc etc. For each consideration it makes, you start with "all else being equal". Then figure there will be dozens, if not hundreds or thousands of these "all else being equal". Then once the plan is selected and the rubber meets the road, we have to contend with the fact "all else is hardly ever equal".

Select All in HGrid/Table

Hello All,
I want to select all the rows in the table that is being shown in the Hgrid (not just in the page). Would this be possible. I saw some previous questions on the issue but could not get a clear answer.
I see that when i click the next/prev links the control comes till the controller and i can see the events raised. But the select all does not even come to the controller to be captured. Do let me know if you think this can be done.Any pointers would be helpful.
Thanks

Select All in a table does not work for Drag and Drop

Hi. I am using Jdeveloper 11.1.1.2 but have also reproduced in 11.1.1.3.
I am trying to implement drag and drop rows from one table to another. Everything works fine except when I do a Select All (ctrl-A) in a table, the table visually looks like all rows are selected, but when I try to click on one of the selected rows to drag to the other table, only the row I click on is dragged.
I tried setting Range Size -1, fetch mode to FETCH_ALL, content delivery to "immediate" but nothing works.
I even have reproduced not using a view object but just a List of beans with only 5 or 10 beans showing in the table.
Does anyone know how to get Select All to work for a Drag Source?
Thanks.
-Ed

OK, thanks for looking into that. I also submitted this service request, which includes a simple sample app to demonstrate the problem:

Performance issue when using select count on large tables

Hello Experts,
I have a requirement where i need to get count of data from a database table.Later on i need to display the count in ALV format.
As per my requirement, I have to use this select count inside a nested loops.
Below is the count snippet:
LOOP at systems assigning <fs_sc_systems>.
LOOP at date assigning <fs_sc_date>.
SELECT COUNT( DISTINCT crmd_orderadm_i~header )
   FROM crmd_orderadm_i
   INNER JOIN bbp_pdigp
       ON crmd_orderadm_iclient EQ bbp_pdigpclient               "MANDT is referred as client
     AND crmd_orderadm_iguid EQ bbp_pdigpguid
     INTO w_sc_count
WHERE crmd_orderadm_i~created_at BETWEEN <fs_sc_date>-start_timestamp
     AND <fs_sc_date>-end_timestamp
     AND bbp_pdigp~zz_scsys   EQ <fs_sc_systems>-sys_name.
endloop.
endloop.
In the above code snippet,
<fs_sc_systems>-sys_name is having the system name,
<fs_sc_date>-start_timestamp is having the start date of month
and <fs_sc_date>-end_timestamp is the end date of month.
Also the data in tables crmd_orderadm_i and bbp_pdigp is very large and it increases every day.
Now,the above select query is taking a lot of time to give the count due to which i am facing performance issues.
Can any one pls help me out to optimize this code.
Thanks,
Suman

Hi Choudhary Suman ,
Try this:
SELECT crmd_orderadm_i~header
INTO it_header                 " interna table
FROM crmd_orderadm_i
INNER JOIN bbp_pdigp
    ON crmd_orderadm_iclient EQ bbp_pdigpclient
   AND crmd_orderadm_iguid   EQ bbp_pdigpguid
   FOR ALL ENTRIES IN date
WHERE crmd_orderadm_i~created_at BETWEEN date-start_timestamp
                                      AND date-end_timestamp
   AND bbp_pdigp~zz_scsys EQ date-sys_name.
    SORT it_header BY header.
    DELETE ADJACENT DUPLICATES FROM it_header
    COMPARING header.
    describe table it_header lines v_lines.
Hope this information is help to you.
Regards,
José

Selecting all columns from table in a model query

I have written a model query which joins 4 tables, applies some rules and returns updated rows by selecting 4 columns out of this. Currently it works fine because all 4 columns are from MODEL aliases. Now I need to select 16 more columns in the same query but none of these columns is added in MODEL aliases. When I tried selecting these columns I got oracle error ORA - 32614. Can someone please guide me to include these columns in the same model query?
I tried couple of options but no luck. Here are those options for ready reference:
1. I cannot nest existing model query into another select because there are no columns avaiable to join in output of current query to map with other records.
2. I cannot include all 16 columns in MODEL aliases because some of these columns are actually output of user defined functions.
I am using Oracle database version 11g Release 11.2.0.1.0.

I am new to SOA Suite and I am using Soa Suite version 10.1.3.1 and Jdev version 10.1.3.3. It is required to select data from one database using the database adapter and insert it in a table in another database. I implemented the flow using DBadapters select operation the problem is everytime I am running the instance it transfers only one row though no condition has been specified on the select. Could anyone please help me out and let me know how to transfer a complete table from one database to another using DBadapters and in a single instance.

Select All rows in WebDybpro Tables

Hi All ,
I am working on NWCE 7.1 . i have table in my UI. and want to give slect all rows functionality in table. in NWCE is there
any way to give select all rows in table with out using , button and writing action to iterate node bound to table.
also i want to know about RowCreator ui element for table.(when we right click on table we get insert -> rowcreator). How this works
Thanks in advance
Regards
Kavita

Hi Kavita,
The row creator Ui element is not visible in table itself you can see it only in outline window.
and in its on create event you have to write the code which i have provided above. it will not be visible in table at design time but at run time when you will click on the last rows lead selection it will call the associated event and one row will be added to the table.

Column alias to select all fields in only one table in a join

Hi,
Please can you tell me if it is possible to use something like "SELECT a*" to select all fields in table a when using a join to join 2 tables e.g a and b? Instead of using "select acomlumn1 acomlumn2 acomlumn3" etc.
Thanks and Regards.

HI,
It is not possible... You have to specify all the fields you want to select with the tilde '~' symbol...
or,
The other solution can be to fetch all the fields from the first table and use 'For all entries' of this table to fetch all fields from the other table...

HS connection to MySQL fails for large table

Hello,
I have set up an HS to a MySql 3.51 dabatabe using an ODBC DNS. My Oracle box has version 10.2.0.1 running in Windows 2003 R2. MySQL version is 4.1.22 running on a different machine with the same OS.
I completed the connection through a database link, which works fine in SQLPLUS when selecting small MySQL Tables. However, I keep getting an out of memory error when selecting certain large table from the MySQL database. Previously, I had tested the DNS and ran the same SELECT in Access and it doesn't give any error. This is the error thrown by SQLPLUS:
SQL> select * from progressnotes@mysql_rmg where "encounterID" = 224720;
select * from progressnotes@mysql_rmg where "encounterID" = 224720

I have read the MySQL documentation and apparently there's a "Don't Cache Result (forward only cursors)" parameter in the ODBC DNS that needs to be checked in order to cache the results in the MySQL server side instead of the Driver side, but checking that parameter doesn't work for the HS connection. Instead, the SQLPLUS session throws the following message when selecting the same large table:
SQL> select * from progressnotes@mysql_rmg where "encounterID" = 224720;
select * from progressnotes@mysql_rmg where "encounterID" = 224720
ERROR at line 1:
ORA-02068: following severe error from MYSQL_RMG
ORA-28511: lost RPC connection to heterogeneous remote agent using
SID=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.0.0.120)(PORT=1521))(CONNECT_DATA=(SID=MYSQL_RMG)))
Curiously enough, after checking the parameter, the Access connection through the DNS ODBS seems to improve!
Is there an aditional parameter that needs to be set up in the inithsodbc.ora perhaps? These are current HS paramters:
# HS init parameters
HS_FDS_CONNECT_INFO = MYSQL_RMG
HS_FDS_TRACE_LEVEL = ON
My SID_LIST_LISTENER entry is:
(SID_DESC =
(PROGRAM = HSODBC)
(SID_NAME = MYSQL_RMG)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
Finally, here is my TNSNAMES.ORA entry for the HS connection:
MYSQL_RMG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.120)(PORT = 1521))
(CONNECT_DATA =
(SID = MYSQL_RMG)
(HS = OK)
Your advice will be greatly appeciated,
Thanks,
Luis

First of all please be aware HSODBC V10 has been desupported and DG4ODBC should be used instead.
The root cause the problem you describe could be related to a timeout of the ODBC driver (especially while taking care of the comment: it happens only for larger tables):
(0) [MySQL][ODBC 3.51 Driver]MySQL server has gone away (SQL State: S1T00; SQL
(0) Code: 2006)
indicates the Driver or the DB abends the connection due to a timeout.
Check out the wait_timeout mysql variable on the server and increase it.

Select All problems on an updateable report

Greetings. I have a problem with the Updateable Report functionality in Apex version 3.0.1.00.07. I'd love to demonstrate the problem, but my account at apex.oracle.com is version 3.2.0.00.27, and apparently, the Updateable Report functionality has been removed from that version. Does anyone know if there's a way to create an Oracle account using older versions?
My problems, in brief, are that when you have more than one updateable report region on the same page, clicking Select All on either table selects all rows of both tables; and that if both tables have only one row, clicking on Select all does nothing.
Please see http://docs.google.com/Doc?id=dccf36js_40gmczpddd for a more detailed problem description.
Any thoughts on how to solve either or both of these problems is much appreciated. Thanks!

Hi,
Firstly, you can still create Updatable reports in the latest version of Apex. Create a Report using the SQL Wizard and, when the report region has been created, change the report type.
Secondly, the checkboxes for both reports are being ticked/unticked together as the javascript being run assumes that there is only one updatable report on the page and, therefore, only one set of "f01" checkboxes. You can get around this by overriding the javascript by adding your own version.
Create a new region in the Before Footer region of the page and using No Template (so that the region is hidden) and use the following as the source:
<script type="text/javascript">
function checkAll(masterCheckbox) {
var p = masterCheckbox.parentNode;
while (p.tagName != 'TABLE')
    p = p.parentNode;
var f = p.getElementsByTagName("input");
if (masterCheckbox.checked) {
    for (var i = 0; i < f.length; i++) {
      if (f.type == "checkbox") {
if (f[i].checked==false) {
f[i].checked=true;
highlight_row(f[i],i);
} else {
for (var i = 0; i< f.length; i++) {
if (f[i].type == "checkbox") {
if (f[i].checked == true) {
f[i].checked = false;
highlight_row(f[i],i);
</script>
I have done this here: [http://apex.oracle.com/pls/otn/f?p=267:82]
One thing though... What happens when the user submits the page? Both reports will have "f01" checkboxes with values starting from 1 and only those that are ticked are submitted with the page. Thus, a checkbox with a value of 1 could refer to either report.

Need help in optimisation for a select query on a large table

Hi Gurus
Please help in optimising the code. It takes 1 hr for 3-4000 records. Its very slow.
My Select is reading from a table which contains 10 Million records.
I am writing the select on large table and Retrieving the values from large tables by comparing my table which has 3-4 k records.
I am pasting the code. please help

Hi,
1) RESULT_PACKAGE internal table contains any duplicate records or not bassed on the where condotion like below
2) Remove the into CORRESPONDING FIELDS OF table instead of that into table use.
refer the below code is
RESULT_PACKAGE1[] = RESULT_PACKAGE[].
sort RESULT_PACKAGE1 by /BIC/ZREB_SDAT AGREEMENT /BIC/ZLITEM1.
delete adjustant duplicate form RESULT_PACKAGE1 comparing /BIC/ZREB_SDAT AGREEMENT /BIC/ZLITEM1.
SELECT /BIC/ZSETLRUN AGREEMENT /BIC/ZREB_SDAT /BIC/ZLITEM1
from /BIC/PZREB_SDAT
into table i_tab
FOR ALL ENTRIES IN RESULT_PACKAGE1
where
/bic/ZREB_SDAT = RESULT_PACKAGE1-/BIC/ZREB_SDAT
AND
AGREEMENT = RESULT_PACKAGE1-AGREEMENT
AND /BIC/ZLITEM1 = RESULT_PACKAGE1-/BIC/ZLITEM1.
and one more thing your getting 10 million records so use package size in you select query.
Refer the following link also For All Entry for 1 Million Records

How to select data from all HR Master Tables(PA0000 to PA****)

Hi Gurus!
My requirement is to pick the changedon(AEDTM) , changedby(UNAME) and reason for change(PREAS) from all tables (pa0000 to pa****)of HR in which he made any change during a specific date.
Now if it is specific for two or three tables then inner join can solve it. but now it is the matter of picking data from maximum 9999 tables for which inner join will not be accurate.
plz suggest me any appropriate way to solve it out. or there is any table which store the changes in All HR Master Tables.
Thanking in Advance.
Tahir Naqqash

Hi,
it is very tidious to get it in one go, as u know hr tables contains huge data.
You can chack my wiki in https://wiki.sdn.sap.com/wiki/x/XYC0Aw .
Here you need to make the following modification.
1. in the selection screen set on date range with select option.
2. in the select query, change select * by ur specified fields.
3. change dynamic internal table and ALV as per ur required fields
In this way you have to put the table name and the date range and will get the data.
for repeation u can call the same job in background again and again store data in a seperate internal table and display finaly ..... but huge chance of getting 'Time Out ' error in that case for comparetively large day gap.

Anirban

Select all in table element

Hello all,
I created a table element which contains a column of check boxes.
I want to add to my table an option to check/uncheck all the check boxes.
I already created the events but I dont know how to call the events I created using the table?
Thanks in advance,
Tomer

Hi Tomer,
you haven't said how your gui should look like. For example you can add two buttons ("select all" and "Unselect all") for this task. Now you add two actions, one for each button. Add the actions as eventtarget in the properties of the buttons. And in the event-methods of the actions you write your code to select/deselect the checkboxes, like
public void onActionSelectAll(...) {
    for (int i = 0; i < wdContext.nodeMyTableDataSource().size(); i++) {
        wdContext.nodeMyTableDataSource().getMyTableDataSourceElementAt(i).setMyCheckboxAttribute(true);
public void onActionUnselectAll(...) {
    for (int i = 0; i < wdContext.nodeMyTableDataSource().size(); i++) {
        wdContext.nodeMyTableDataSource().getMyTableDataSourceElementAt(i).setMyCheckboxAttribute(false);
HTH,
Frank
