How to SELECT ALL records of a TABLE VIEW in the BSP page

Hi All,
In the BSP portal, I am displaying some data(multple records) in the form of a table using the BSP TAG <htmlb:tableView>. I wrote the logic in the 'VIEW' of the BSP application which will be triggered by the controller. I have used the attribute selectionMode = "MULTISELECT" to have a Check Box to select a row.
My requirement is to have a button/checkbox on the first column of the header of the table view. By clicking on this, it should select/desect all the records of the table. Could someone please help me how to do this? What attribute I should use in the tableview to get the button in the header row of the table and how to select all the records of the table.?
Please provide your valuable inputs.
Thanks & Regards,
Paddu.

Select all fields of a table while designing the layout of a query

Can some one tell me how to select all fields of a table at a single stroke while designing the layout of a query....this would greatly reduce the time spent to select each and every field of a table into the layout....
Thanks in advance

Hi,
Declare your internal table (Say it is itab).
Then :-
Select * from <tablename>.
Eg,.Select * from mara.
Then display it using:-
Loop at itab.
write:/ wa_itab. "Workarea.
endloop.

How to select all indexes in a schema , for gathering the statistics

In OEM 10g , How can we select all the indexes in a particular schema for gathering the statistics.
For example , consider the schema got 1500 indexes. When i clicked on select all , it is selecting 10 indexes in one stretch ( all which are present in that page).
For 1500 indexes , i have to make 150 such selection.
How can we avoid it.
In 9i OEM, its quite simple. With just 1 mouse clicke , we can select all the indexes .
Thanks

On the Administration Tab of the instance, choose Statistics Management - Manage Optimizer Statistics, then Gather Optimizer Statistics and click Continue. You then get a choice of Database, Schema, Tables or Indexes.
Stupid that you have to supply an OS username and password to do this but anyway.

How to select rows or columns of tables without using the mouse?

2nd post ever! Yeah! \m/
In Excel, I can select entire rows or columns of data WITHIN TABLES--i.e., not selecting entire sheet rows or columns--by going to any cell on the perimeter of the table, holding down shift+ctrl, and clicking a direction arrow. So for example, if I have a table in columns D-G and rows 1-5, I can highlight row 4 by going to the first or last cell of that row, holding down the shift+ctrl, and hitting the appropriate direction arrow. You might think this is superfluous given that you can use the mouse to select cells. But that becomes cumbersome with large tables, and this method can be more efficient even with small tables.
Similarly, it's often useful to navigate tables, particularly large ones, by moving from any cell within the table to the end or beginning of that row or column by holding down ctrl and hitting the appropriate arrow key. In Excel, this ctrl+arrow key method also allows you to skip blank cells, which is another very useful navigational feature.
I tried numerous combos involving shift, ctrl, command, alt/option and the arrow keys. Haven't found a way to do any of this yet.
Anyone?

Hi Josh,
Numbers is organized differently than Excel, and the navigation tools are different too. Many of us miss our particular favorites from spreadsheets past, but this is Numbers, not a clone. The biggest adjustment is to go from huge monolithic sheet-tables containing virtual sub-tables to a simple blank sheet with small tables, sometimes many per sheet. Navigating is no big deal in these small tables and neither is getting from one small table to another, using the Sheets pane.
Selecting a particular Table is as easy as clicking on the table's name in the Sheets pane. Selecting a particular row, or column, or ranges of rows or columns is done by clicking on the table's row and column labels, left side and top side once a cell is selected in the table.
Numbers is weak at handling large Tables and documents that are large overall. We know this and many of us still prefer it to the alternative when the tool fits the task.

Periodical start of workflow selecting all records

Hi,
We want to periodical start a workflow. This workflow should be run for all records of the repository.
How to select all records?
How to start a workflow periodically?
can anyone help me?

Hello H. Antonise
First of all
Not recommend use that for all records in your repository or for many records
Second of all
for autolaunch workflow sap mdm have many conditions
Of course you can use MDM API (Java) for workflow management - that is simple way if you know JAVA programming language
and more hard way if you wolud like it without programming:
1) add tech field in repository
2) create your workflow and set
trigger action: record update
active : yes
Max Records:0
autolaunch : Immediate
once in time interval wich you set in mds.ini file workflow will be launch(by default every 5 minutes)
3)create file for import some value to that field for all records
(remember about my warning!!!)
4) configure mdis for automatic import that file
5) configure some task manager - it should to put your source file once a day to your inbound directory(use standard task manager for windows or "Cron" for Unix-like systems or some another program)
each another way the same just:
in point 3
Import Manager options set Checkout/Workflow =[your workflowname]
in that case after import your workflow will be start immediatly for all updated records
more about how it work you can founf in standard documentation :

Select all rows in af:table

Hi,
I need to select all rows in af:table, not only on current page.
I have following code on custom select all action:
getTable2().getSelectionState().addAll()and on button that needs to perform some action on selected rows I have this code
        Set selectedRowSet = getTable2().getSelectionState().getKeySet();
        if (!selectedRowSet.isEmpty()) {
            Iterator it = selectedRowSet.iterator();
            while(it.hasNext()) {
                Key key = (Key)it.next();
       }selectedRowSet.iterator() method throws java.lang.ClassCastException: oracle.jbo.Key.
When I select rows with af:tableSelectMany, which is inside selection facet and selects only rows on current page, this works fine.
Any ideas?
Thanks

Hi,
you can only access those data that is queried and part of the CollectionModel to the time you select all
   RichTable _table = employeesBackingBean.getEmployeeTable1();
   RowKeySet rks = new RowKeySetImpl();
CollectionModel model = (CollectionModel)_table.getValue();
int rowCount = model.getRowCount();
      for (int i = 0; i < rowCount; i++) {
           model.setRowIndex(i);
           //note that in the simple POJO case, the row key is the same
           //as the index. However, it would be wrong to just rely on this
           //because other models or custom table models my return a more
           //comples key. Therefore we iterate over the available rows to
           //obtain the keys.
           Object key = model.getRowKey();
           //add the row keys to the RowKeySet to mark selected
           rks.add(key);
   _table.setSelectedRowKeys(rks);
   AdfFacesContext.getCurrentInstance().addPartialTarget(_table);Frank

-Sandip

Rashmi/Kukku,
First of all, Thanks for your help!
Is there any other way in which we can access tables other than using BAPIs or RFCs?
In my case, there is a table structure which has to be updated with values after validating a key. i don't think there is any RFC available now. do i need to create bapi/rfc for that?

How to select all the colomns_names from a table, with their datatypes ..

hi :)
i would like to know, how to select in SQL all the columns names from a table with their datatypes so that i get something like this :
Table 1 : table_name
the column ID has the Datatype NUMBER
the column name has the Datatype Varchar2
Table 2 : table_name
the column check has the Datatype NUMBER
the column air has the Datatype Varchar2
and that has to be for all the tables that i own ! ..
P. S : i m trying to do this with java, so it s would be enough if you just tell me how to select all the tables_names with all their colums_names and with all their datatypes ! ..
thank you :)
i ve heard it can be done with USER_TABLES .. but i have no idea how :( ..
Edited by: user8865125 on 17.05.2011 12:22

Hi,
The data dictionary view USER_TAB_COLUMNS has one row for every column in every table in your schema. The columns TABLE_NAME, COLUMN_NAME and DATA_TYPE have all the information you need.
Another data dictionary view, USER_TABLES, may be useful, too. It has one row pre table.

How to show all records by default on search result page?

Hi
I am trying to make a search page that would execute the search in the database based on one or more field constraints.
(Using MySQL,PHP)
I have 2 columns in the database "vm_ip" (primary key) <IP address>, "Operating_System" <Any, Windows, Solaris, AIX>
need to search vm_ip based on other two fields.
PROBLEM: Need to show all the record when I select "Any" in the Operating_System drop down menu.
<p>Operating System:
    <select name="os_select" id="os_select">
    <?php
$os_count=1;
foreach($os_type as $value) //(os_type is array with possible values of OS)
echo "<option value=".$os_count.">".$value."</option>";
    $os_count++;
?>
      <option value=" " selected="selected">Any</option>
    </select>
</p>
this code POSts NULL value to the search page.
Below code is of recordset on search page
$varOS_virtual = "Operating_System"; // recordset variable set to same as column name (default value)
if (isset($_POST['os_select'])) //this should not be true
$varOS_virtual = $_POST['os_select'];
mysql_select_db($database_xyz_db, $xyz_db);
$query_virtual = sprintf("SELECT table.VM_IP FROM table
WHERE table.Operating_System=%s", GetSQLValueString($varOS_virtual, "int"));
$virtual = mysql_query($query_virtual, $xyz_db) or die(mysql_error());
$row_virtual = mysql_fetch_assoc($virtual);
$totalRows_virtual = mysql_num_rows($virtual);
I expected the 'os_select' field to be null and default value of Operating_System to be "Operating_System" so that the Query shows all records.
But instead the value being passed in the Query is "0". and no records are shown.
What can I do to show all records?
As probably obvious I am new to php/MySQL so all the help is most welcomed .
Thanks

Hi
Thanks for the prompt reply but this does not solve my problem.
First thing I appologise for giving you incorrect info. Actually I have many more constraints on the search apart from OS.
Didn't think I would get single constraint specific ans.
Here is what all i tried and problems I faced:
1. I cannot use seperate queries cause I have around 7-8 other constraints on the search.
2. I cannot play around with the Record set code. For some reason even if I mess with it a little bit Dreamweaver stops recognising the recordset. for eg i tried the below code:
$query_virtual = sprintf("SELECT table.VM_IP FROM table WHERE
table.Operating_System=%s ,($_POST['os_select']=="")? TRUE:GetSQLValueString($varOS_virtual, "int"));
this ran well for the first time, and then the record set was screwed up. kept on asking me to "Discover" the links, which it couldn't do.
3. take a look at this code:
$varOS_virtual = "Operating_System";
if (isset($_POST['os_select'])) {
$varOS_virtual = $_POST['os_select'];
$varState_virtual = "State";               //second constraint
if (isset($_POST['state_select'])) {
$varState_virtual = $_POST['state_select'];
mysql_select_db($database_xyz, $xyz);
$query_virtual = sprintf("SELECT table.VM_IP FROM table AND table.Operating_System=%s AND State=%s",
GetSQLValueString($varOS_virtual, "int"),GetSQLValueString($varState_virtual, "int"));
$virtual = mysql_query($query_virtual, $xyz) or die(mysql_error());
$row_virtual = mysql_fetch_assoc($virtual);
$totalRows_virtual = mysql_num_rows($virtual);
here on passing NULL value for "Any" GetSQLValueString($varOS_virtual, "int") functions returns NULL and though the Default value of
varOS is set to 'Operating_System" query takes NULL value only which when executed shows no records.
My problem majorly revolves around how to put something like "WHERE Operating_System= Operating_System" OR "WHERE Operating_System= TRUE" in the query, when passed through variable they are sent as Strings or NULL.
Thats why WHERE 1=1 also doesnt work, because it has "WHERE Operating_System= NULL" in AND.
Logically when NULL is passed default value of variable should comeinto picture, but tha isnt happening.
Thanks again for answering. hope I was able to explain my problem.

How can i fetch records from 3 tables in a single query without using join

Hi.
Can any body please tell me <b>How can i fetch records from 3 tables with a single query without using joins</b>
Thanx
prabhudutta

Hi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.

How to select all the people that are not in any equipe ?

Hi,
I have a nice SQL expression that gives me as a result all the "AGENTS" (people) that are working in an EQUIPE (a team)
select a."AGENT_ID",
a."NOM" || ' ' || a."PRENOM" "Nom",
c.libelle "Equipe",
a."DATE_EMBAUCHE" "Date embauche",
a."DATE_DEBAUCHE" "Date débauche"
from OBSERVATOIRE."AGENT" a,
observatoire.equipe_agents b,
observatoire.equipe c
where a.agent_id = b.agent_id
and b.equipe_id = c.equipe_id
order by nom
Now, how to select all the agents that are NOT working in any "EQUIPE" (team) ?
I have tried but could not succeed !
Thank you for your kind help.

Christian from France wrote:
It is not working because the table EQUIPE_AGENTS does not contains a row if the agent is not into any equipe.
CREATE TABLE "OBSERVATOIRE"."EQUIPE_AGENTS"
(     "EQUIPE_AGENTS_ID" NUMBER NOT NULL ENABLE,
     "EQUIPE_ID" NUMBER NOT NULL ENABLE,
     "AGENT_ID" NUMBER NOT NULL ENABLE)
CREATE TABLE "OBSERVATOIRE"."AGENT"
(     "AGENT_ID" NUMBER NOT NULL ENABLE,
     "GRADES_ID" NUMBER NOT NULL ENABLE,
     "NOM" VARCHAR2(50 BYTE) NOT NULL ENABLE,
     "PRENOM" VARCHAR2(50 BYTE),
     "DATE_EMBAUCHE" DATE NOT NULL ENABLE,
     "DATE_DEBAUCHE" DATE)
The only way to "know" if an agent is not into any equipe (team) is to search into the EQUIPE_AGENTS table, and if we do not find the ID of the agent into this table, then we know that this agent is not into any EQUIPE (team).
I don't know ho to translate this into SQL.And that's what my query does. It uses an OUTER JOIN so that a result record is returned whether or not there is a record in EQUIPE_AGENTS. And the check for EQUIPE_ID is NULL restricts the result set to those where there IS NOT a record in EQUIPE_AGENTS.
A more traditional way would be to use NOT IN or NOT EXISTS clauses, but they can prove inefficient.

How to select every row in a table in case there is no user input ?

My control block is : DUMMY_BLK . It has field : RPTNO.
My base Block is : T_UNLDLD_BLK .
In the property palette, the where clause is : ULD_RPTNO = :DUMMY_BLK.RPTNO
When the user presses the search button , he gets results according to the report no keyed in . My when-button-pressed trigger contains the following code:
go_block('T_UNLDLD_BLK');
execute_query;
If the RPTNO is null , I should get displayed all records from T_UNLDLD table .
How can I do that , what do I need to add to the where clause please?
Thanks.

I think using same trick will work in this case also.
Modify your where clause as:
ULD_SHP_AGCODE LIKE NVL(:DUMMY_BLK.SA_NAME,'%') AND TRUNC(ULD_ETA) BETWEEN nvl(:DUMMY_BLK.ETA,'15-aug-1947') AND nvl(:DUMMY_BLK.ETA_TO,'15-aug-2050').
Please note, i've taken from date as a value in the past and to date as value in future if they are NULL.
I am sure, your ULD_ETA will fall between those two default dates.
Hope it helps.
Please mark answer as helpful / correct, if it helps you

Can any one tell me how to select latest record

Hi,
Can any one tell me how to select latest record. Below is the requirement
select * from a where a_Date=v_date.
out of thousand records with matched condition i need to select latest record
Thanks in advance

user12852882 wrote:

select max(a_date) from aThis will return the last/latest date used from the table.
Secondly, you now want to select the last row - or rows. As a_date may not be a primary key (you did not state it was and usually a date column make poor choice as unique identifier), there could be more than one row with that "+latest date+".
So to find the latest row(s):
select * from a where a_date = (select max(a_date) from a)Or you could do the following:
declare
latestDate date;
begin
// find the latest date and store it for use and re-use
select max(a_date) into latestDate from a;
// now process the last row(s) - and consider rewriting this
// as a bulk processing loop
for c in (select * from a where a_date = latestDate)
loop
.. do something with the row
end loop;
// now use latestDate variable for some other
// required processing
.. code goes here ...
end;
