Restricting rights to modify only some rows

Hi,
I just discovered HTML DB and played around with it on myhtmldb.com because htmldb.oracle.com is down for some reason.
Is there a way to restrict write access to some rows of a table for each user? For example everybody can see the whole table but you can only add/delete/modify the rows where your id/company name/.. is present in one column.
Cheers
Mathias

How to edit only some rows in ALV

Hi Experts,
I have editable ALV. I need to allow edit only for some rows, not generaly all of them.
Do you have any idea how to do it?
I use ALV through FM module REUSE_ALV_GRID_DISPLAY.

Download link for only some rows

Hi,
I have 2 tables. One contains records for products, and the other contains images for only some of the products. The images have been uploaded through the application and therefore are in a 'upload_data' table.
The tables are linked by product_id.
I would like to display a report that shows all the column from the products table and a download link for only those products that have an image.
So far the query only returns those rows that have an image.
Thanks

What does this query look like?

Only some rows selectable

Hi,
I wonder if anybody could help me in my problem?
I made a table and would like only some of the rows to be selectable. Is this possible?
The best solution would be to hide those squares on the left of the rows.
Thanks in advance for your help.
Piotrek
Edited by: Piotr Kondratowicz on Feb 10, 2009 4:29 PM

Hi Piotr,
Create a value attribute of type boolean(Ex: ed) and assign it to all editable fields of the table.
Based on a condition enable(ed=true)/disable(ed=false) the row fields as read only.Which will fulfill your requirement.
Thanks & Regards,

Counting only some rows without where or subqueries?

Is it possible with oracle to count only some of the rows? I mean without excluding the rows in where or using sub queries.
This does not work but I think it illustrates what I want:
SELECT count(flags), count(flags like '%P%'), count(flags like '%F%') FROM table WHERE some_column = 2;
Where the first would return the number of flags rows, while the second contet the numbers that have P in them and the third counted the number with F.
Table would be
Flags Some_column
'AFP' 2
'A* 1
'PF' 1
'P' 2
And so on.
In postgres you can do: count(substring(flags from 'R')), to achieve the above mentioned idea. Does oracle have a way of doing the same?

Your requirement is not clear. But.. Is this what you are trying to achieve?
SQL> with t
2 as
3 (select 'AFP' st from dual
4 union all
5 select 'A*' from dual
6 union all
7 select 'PF' from dual

ALV - how to make selectable only some rows on an ALV?

Hi my problem is:
I have an ALV GRID as output of a report.
I have to make selectable only few rows based on the contents of a field (showed in a column in the ALV).
Is it possible?
Best Regards, Vincenzo

I did understand, but as i told you there is nothing like that, neither an option nor an event to capture.
Here is the documentation: http://help.sap.com/saphelp_erp2005vp/helpdata/EN/bf/3bd1369f2d280ee10000009b38f889/frameset.htm

Hotspot click for only some rows in ALV grid for a particular column ?

Hi there,
        In ALV grid, we can make Hotspot enable for all rows in a specified column
by specifying in the fieldcatalog with Hotspot attribute set as true.
But I want to enable Hotspot only for certain rows in the particular column. I tried with MC_STYLE4_LINK , but I didnt got the required result.
So , how could I achieve that in ALV grid.
Points would be rewarded for helpful answers.

Hi,
You can do it for a column. Please refer to the code snippet below,

LOOP AT it_fcat INTO wa_fcat.
IF wa_fcat-fieldname = 'STATUS'.
    wa_fcat-hotspot = 'X'.
    MODIFY it_fcat FROM wa_fcat.
    CLEAR wa_fcat.
ENDIF.
ENDLOOP.
CALL METHOD l_obj_alv_grid->set_table_for_first_display
      EXPORTING
    i_structure_name              = 'SMMW_ALERTS_ICON_S'

        it_fieldcatalog               = it_fcat.
In the above replace the structure 'SMMW_ALERTS_ICON_S' with your structure and column 'STATUS' with your desired column.
Hope this helps,

Select only some rows

Hi all,
I've a query with more than 500 rows as result. I'm only interested to show the first 50 rows. Did you know any way to prepare the select sentence to do it? I prefer avoid use cursors to do that.

hi
use ROWNUM keyword for fetching first 50 rows
simplest example
select * from emp
where rownum < 5 ;
regards
HiteshROWNUM applies to the rows after they are collected into a result set. Thus, it may, or may not, fulfill the OP's requirements. He still needs to define what he means by "first 5 rows".

Restricting class access to only some classes.

Hi Guys,
I want my classes to be accessed by only my defined classes. Is it possible?
Say I have public class defined test. I want that this class should be accessed by only the classes I want not by any other class by any mean. If somebody tries to access the class it should result in SecurityException. How can I do that???
Thanks,
Rajan

maybe a package private class will do it, ie package the classes in the same package. define the particular class as protected, it will be visible to other classes in the package, the other classes maybe public.
otherwise maybe it is an protected abstract class that the others extend?
otherwise have this particular class take as arguments the other classes in overloaded methods?
otherwise maybe a strategy pattern and default is a do nothing class (ie throws)?

How can I modify this script to return only certain rows of my mySQL table?

Hi there,
I have a php script that accesses a mySQL database and it was generated out of the Flex Builder wizard automatically. The script works great and there are no problems with it. It allows me to perform CRUD on a table by calling it from my Flex app. and it retrieves all the data and puts it into a nice MXML format.
My question, currently when I call "findAll" to retrieve all the data in the table, well, it retrieves ALL the rows in the table. That's fine, but my table is starting to grow really large with thousands of rows.
I want to modify this script so that I can pass a variable into it from Flex so that it only retrieves the rows that match the "$subscriber_id" variable that I pass. In this way the results are not the entire table's data, only the rows that match 'subscriber_id'.
I know how to pass a variable from Flex into php and the code on the php side to pick it up would look like this:
$subscriberID = $_POST['subscriberID'];
Can anyone shed light as to the proper code modification in "findAll" which will take my $subscriberID variable and compare it to the 'subscriber_id' field and then only return those rows that match? I think it has something to do with lines 98 to 101.
Any help is appreciated.

* performs the basic db operations (FIND, INSERT, UPDATE, DELETE)
* and then serialize the response in an XML format.
* XmlSerializer uses a PEAR xml parser to generate an xml response.
* this takes a php array and generates an xml according to the following rules:
* - the root tag name is called "response"
* - if the current value is a hash, generate a tagname with the key value, recurse inside
* - if the current value is an array, generated tags with the default value "row"
* for example, we have the following array:
* $arr = array(
*      "data" => array(
*           array("id_pol" => 1, "name_pol" => "name 1"),
*           array("id_pol" => 2, "name_pol" => "name 2")
*      "metadata" => array(
*           "pageNum" => 1,
*           "totalRows" => 345
* we will get an xml of the following form
* <?xml version="1.0" encoding="ISO-8859-1"?>
* <response>
*   <data>
*     <row>
*       <id_pol>1</id_pol>
*       <name_pol>name 1</name_pol>
*     </row>
*     <row>
*       <id_pol>2</id_pol>
*       <name_pol>name 2</name_pol>
*     </row>
*   </data>
*   <metadata>
*     <totalRows>345</totalRows>
*     <pageNum>1</pageNum>
*   </metadata>
* </response>
* Please notice that the generated server side code does not have any
* specific authentication mechanism in place.
* The filter field. This is the only field that we will do filtering after.
$filter_field = "subscriber_id";
* we need to escape the value, so we need to know what it is
* possible values: text, long, int, double, date, defined
$filter_type = "text";
* constructs and executes a sql select query against the selected database
* can take the following parameters:
* $_REQUEST["orderField"] - the field by which we do the ordering. MUST appear inside $fields.
* $_REQUEST["orderValue"] - ASC or DESC. If neither, the default value is ASC
* $_REQUEST["filter"] - the filter value
* $_REQUEST["pageNum"] - the page index
* $_REQUEST["pageSize"] - the page size (number of rows to return)
* if neither pageNum and pageSize appear, we do a full select, no limit
* returns : an array of the form

How to restrict only one row in Table ??.

Hi all,
i want to restrict no. of rows to one,
that is not more that one row should be there in the table.
Following trigger works well in all conditions
except:
insert into myTab select 'x' from emp;
inserts 14 rows.
Create or replace trigger one_row_myTab
before insert on myTab
for each row
declare
cnt number;
pragma AUTONOMOUS_TRANSACTION;
Begin
select count(*) into cnt from mydual;
if cnt=1 then
raise_application_error(-20001,'MyDual Can have only one Row');
end if;
end;
i think with trigger it w't be possible because,
same transaction triggers c't query the table (Mutating Table),
Autonomus trans ca't identify uncommited changes.
pls add your suggestions.
Thanks for Reading the Post.

Display commandButton in some rows only

In my handler, I created a dynamic datatable. How can I add a command button in some rows only ? I tried to use setRendered but it doesn't work...
HtmlDataTable _dataTable = new HtmlDataTable();
_dataTable.setId("table1");
_dataTable.setVar("table1");
_dataTable.setValueBinding("value", application.createValueBinding(#{lpHandler.shpModel}));
UIColumn _addColumn = new UIColumn();
HtmlCommandExButton _addCommand = new HtmlCommandExButton();
String _addAction = "#{hksHandler.editLPOutcome}";
MethodBinding _addActionBinding = application.createMethodBinding(_addAction,null);
_addCommand.setAction(_addActionBinding);
_addCommand.setRendered(_dataTable.getRowIndex() > 0);
_addColumn.getChildren().add(_addCommand);
_dataTable.getChildren().add(_addColumn);
Thanks in Advance

To expand on this a little more, when you have a data table the components inside the data table only occur once. That is, there is one instance of the command button you have created. During the render process, the subcomponents of the data table are rendered many times, once for each row. What you have done is set the value of the rendered property for the command button once, to whatever static value (_dataTable.getRowIndex() > 0) has at the time you invoke it. So the value for rendered is the same for each row, so you either always get the button or never get the button. In order to make the rendered value dependent on the row, use must set the rendered using a value expression, in the same way you did with the value property for the data table.

How to copy only some coulums and rows from excel files to a Oracle Table

Dear all,
I have the following problems:
How to copy only some wanted coulums ( I.e DATETIME(format:17/09/2007 00:00:01 ) and TIME (format: 00:00:01 ) from excel files to oracle table.
HOPE TO GET HELP FROM YOU GUYS!
SINCERELY,
MONOJSHARMALUITEL

How about Heterogeneous Services so that the Excel sheet is an external database:
1- Go to Control Panel>Administrative Tools>Data Sources (ODBC)>System DSN and create a data source with appropriate driver. Name it EXCL.
2- In %ORACLE_HOME%\Network\Admin\Tnsnames.ora fie add entry:
EXCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.12.0.24)(PORT = 1521))
(CONNECT_DATA =
(SID = EXCL)
(HS = OK)
Here SID is the name of data source that you have just created.
3- In %ORACLE_HOME%\Network\Admin\Listener.ora file add:
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = <hs_sid>)
(ORACLE_HOME = <oracle home>)
under SID_LIST_LISTENER like:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = d:\ORA9DB)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = ORA9DB)
(ORACLE_HOME = d:\ORA9DB)
(SID_NAME = ORA9DB)
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = EXCL)
(ORACLE_HOME = D:\ora9db)
Dont forget to reload the listener
c:\> lsnrctl reload
4- In %ORACLE_HOME%\hs\admin create init<HS_SID>.ora. For our sid EXCL we create file initexcl.ora.
In this file set following two parameters:
HS_FDS_CONNECT_INFO = excl
HS_FDS_TRACE_LEVEL = 0
5- Now connect to Oracle database and create database link with following command:
SQL> CREATE DATABASE LINK excl
2 USING 'excl'
3 /
Database link created.
Now you can perform query against this database like you would for any remote database.
SQL> SELECT table_name FROM all_tables@excl;
TABLE_NAME
DEPT
EMP
