Populating a SELECT list from an Oracle Table

Hello,
I would like to populate a second SELECT list on
a web page based on the selected value in the first
SELECT list. I would like to take the value
that the user selects in the first SELECT list and
use it in a WHERE clause to bring back distinct
values to display in the second SELECT list.
I would like to do this all on a single page. As
soon as the user selects a value in the first SELECT
list, then the correct values retrieved from the
database would appear in the second select list.
Is this possible? Do you have sample code or ideas??
I can write JavaScript to get the selected value, but
I cannot get to Oracle data from the JavaScript environment.
I can write PL/SQL or Java procedure to access
Oracle data, but I cannot make the complete connection.
Help, please.
thanks
paul

Unless you can get every combination back in the first SQL statement, you'd have to do something along the lines of
- Have the JavaScript submit the page as soon as the first pull-down is selected
- Have the response be a page identical to the first page, but with the second pull-down populated.
The other option would be to have a Java applet that can make the second query and return results. Since applets can't connect to the database by default, you'd have to have an app server that would do the actual query.

Select data from all the table names in the view

Hi,
"I have some tables with names T_SRI_MMYYYY in my database.
I created a view ,Say "Summary_View" for all the table names
with "T_SRI_%".
Now i want to select data from all the tables in the view
Summary_View.
How can i do that ? Please throw some light on the same?
Thanks and Regards
Srinivas Chebolu

Srinivas,
There are a couple of things that I am unsure of here.
Firstly, does your view definition say something like ...
Select ...
From "T_SRI_%"
If so, it is not valid. Oracle won't allow this.
The second thing is that your naming convention for the
tables suggests to me that each table is the same except
that they store data for different time periods. This would be
a very bad design methodology. You should have a single
table with an extra column to state what period is referred to,
although you can partition it into segments for each period if
appropriate.
Apologies if i am misinterpreting your question, but perhaps
you could post your view definition and table definitions
here.

Display select list from query on manual tabular form

I got so frustrated I started over. I'm following the how to create a manual form.
http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html#MANUAL
The problem I'm now having is even though I display items as hidden, there is a column holder on the report for them. If I go into the report attributes and toggle the show attribute off I cannot reference an items value in my logic. I used /&nbsp/ for the column heading but I still get the little sort arrow where the column heading should be. I tried to toggle the sort attribute off but the sort arrow still shows up. How can I use the apex_item.hidden and not get a place holder for the column on a report? Thanks, Elizabeth

Built in Function to Populate an access table from an Oracle Table through VB 6.0

Dear all,
Is there any built in function in VB 6.0 to populate an access table directly from an oracle table or SQL Server(Assume Both has the same columns & data type).
(Just like the DoCmd command which can be used to populate an excel sheet directly from an access table).
Please help.
Regards
Sibby.

Sibby,
There is no "built-in" code in VB that I am aware of. However, you could use this code which I wrote for SQL Server. For Oracle, you would have to change to the appropriate table to get all the table names. You can filter by table name to get just your tables like I did below (My_).
'* Now select all the files and add to access.
sSQL = "SELECT name, id FROM sysobjects WHERE xtype = 'U' AND SUBSTRING(name, 1, 3) = 'My_' ORDER BY name"
Set rstTemp = OpenRdSetView(sSQL:=sSQL, adoConnection:=adoConnection)
On Error GoTo TableExistError
'* Loop through all my database tables and copy to the Access database.
With rstTemp
Do While Not .EOF
'* Copy this to the Access backup database.
sTableName = .Fields("Name").Value
'* Select all records from the SQL Server table and copy to the local Access database.
sSQL = "SELECT * INTO " & sTableName & " FROM "
sSQL = sSQL & "[odbc;dsn=" & sDSN & ";UID=" & sUID & ";pwd=" & spwd & ";]." & sTableName
adoBackupConnection.Execute sSQL, , adExecuteNoRecords
'* Go to next table.
.MoveNext
Loop
End With

Populate Select List from Checkboxes?

How do I populate a Select List from a checkbox set's checked display values and submitted values?
I'm guessing I need to parse the colon-delimited values, but I have no idea how to get the display values, or how to put all of that into the Select List.
Any ideas?
Cheers,
Ben

Hello,
Every select list item can be based on LOV. You can read more about it in here - http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28550/bldapp.htm#CHDFGFHI
If you are trying to populate a select list, using JavaScript, you can see a good example in here - http://htmldb.oracle.com/pls/otn/f?p=11933:37
Hope this helps,
Arie.

How do I select rows from the same table that have multiple occurances

Hi Everybody,
I am trying to select records from a detail table by grouping it. The table has more than 1 million records and the query is not performing well. The basic question is how to select a distinct record from a table which matches all values in one column and any in the other.
desc SCV
ID NUMBER PK (ID + SCRID)
SCRID NUMBER FK(SC)
ID SCRID
1 1
2 1
3 1
4 2
5 2
6 3
7 4
8 4
desc PROJECTS
ID NUMBER PK
NAME VARCHAR2(100)
ID NAME
1 PROJECT1
2 PROJECT2
3 PROJECT3
4 PROJECT4
desc PJS
ID NUMBER
PROID NUMBER FK (PROJECTS)
SCRID NUMBER FK (SCV(SCRID + SCVID)
SCVID NUMBER
ID PROID SCRID SCVID
1 1 1 1
2 1 1 2
3 1 2 5
4 1 3 6
5 1 4 7
6 2 1 3
7 2 2 4
8 2 2 5
9 2 4 7
There are over 1 million records in PJS.
desc TBP
SCRID NUMBER
SCVID NUMBER
SCRID SCVID
1 1
1 2
1 3
2 4
2 5
3 6
4 7
4 8
The requirement is to select projects that have matching SCRID, SCVID from TBP such that
all distinct SCRID should match and within that and any SCVID match will do. (A "AND" between each SCRID and an "OR" for each SCVID in that SCRID like 'SCRID = 1 AND (SCVID = 1 OR SCVID = 2 OR SCVID = 3) AND SCRID = 2 AND (SCVID =....)
So, for the sample data it should return us PROID = 1
I have few queries written for this:
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 1
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 2
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 3
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 4
This query performs well but the cost is very high, hardcoding, sorting.
The 2nd option is to:
SELECT pjs.PROID proid
FROM TBP tbp,
PJS pjs
WHERE pjs.SCVID = tbp.SCVID
AND pjs.SCRID = tbp.SCRID
GROUP BY pjs.PROID
HAVING COUNT(DISTINCT pjs.SCRID) = (SELECT COUNT(DISTINCT SCRID ) FROM TBP)
This has a low cost but runs slowly.
One more way I tried was with the IN operator like
SELECT DISTINCT PROID FROM PJS A,TBP T WHERE T.SCRID = 1 AND T.SCVID = A.SCVID
AND PROID IN (SELECT PROID FROM PJS A,TBP T WHERE T.SCRID = 2 AND T.SCVID = A.SCVID
AND PROID IN (...SO ON with each DISTINCT SCRID.
Again this involves too much of sorting.
Any help will be appriciated.
Thanks in advance.

Hi Andrew,
Use DELETE t_itab statement inside the loop.
I have modified your code. It is perfectly working.See bellow -
LOOP AT it_zmember01 INTO wa_zmember01.
WRITE: / wa_zmember01-mnumber UNDER 'NUMBER',
wa_zmember01-mname UNDER 'NAME',
wa_zmember01-mdob UNDER 'DOB'.
WRITE / '-----------------------------------------------------------------'.
DELETE it_zmember01. " Modified
ENDLOOP.
DELETE it_zmember01. statement inside the loop will delete the current row of the table.

Select list from query in report

Hello everybody,
I want to include a select list from a query in a report's colomn, but the select list should only be displayed conditionally. I wanted to do this with the help of "case when" in the corresponding SQL statement.
The select list itsself works, but when I combine it with "case when" I always get the error message:

OBIEE 11g - Combine data from two Oracle tables

Good day!
I tried to combine data from two Oracle tables as fact data, but it doesn't work.
My steps: I created SCOTT.EMP2 table from SCOTT.EMP table, update EMPNO and ENAME values of EMP2 table to distinguish data of my tables. Then I imported physical tables DEPT, EMP and EMP2 to BIEE 11g, created joins DEPT-EMP and DEPT-EMP2 in physical diagram. Then I dragged DEPT and EMP tables to BMM, and EMP2 table to EMP as second LTS. In Content tab for EMP and EMP2 I checked "This source should be combined with other sources at this level" checkboxes. Then I renamed logical tables EMP and DEPT to Employees and Departments and dragged them to Presentation area. In Answers I created Analysis with columns DNAME and ENAME.
The problem is that data on results tab is only from one physical table EMP or EMP2 (depending on the order of sources EMP and EMP2 of LT Employees) and not from both.
Can anybody help? Am I missed something?
Al.

Hi Al,
I think you have to define the content of the LTS.
http://download.oracle.com/docs/cd/E12096_01/books/admintool/admintool_BusModSetup16.html
You have to specify the content of the different fragments.
http://download.oracle.com/docs/cd/E12096_01/books/admintool/admintool_SetUpAggNav3.html#wp1005333
Maybe you have to add an additional column 'Source' ('EMP1', 'EMP2')
Good Luck,

How to insert select columns from one internal table to another

Hi,
How to insert select columns from one internal table to another based on condition as we do from a standart table to internal table.
regards,
Sriram

Hi,
If your question is for copying data from 1 int table to other ;
we can use
APPEND LINES OF it_1 TO it_2.
or if they have different columns then:
loop at it_1 into wa_it1.
move wa_it1-data to wa_it2-d1.
apped wa_it2 to it_2.
clear wa_it2.
endloop.

hii
you can do it by using for all entries and with READ statement ..do like follow code
IF i_marc[] IS NOT INITIAL.
    SELECT matnr                       " Material Number
           werks                       " Plants

      FROM mard
      INTO TABLE i_mard
       FOR ALL ENTRIES IN i_marc
     WHERE matnr EQ i_marc-matnr
       AND werks EQ i_marc-werks
       AND lgort IN s_lgort.
ENDIF.                               " IF i_mara[] IS NOT INITIAL
IF sy-subrc EQ 0.
    LOOP AT i_output INTO wa_output.
      READ TABLE i_mard INTO wa_mard WITH KEY matnr = wa_output-matnr.
      wa_output-lgort = wa_mard-lgort.
      MODIFY i_output FROM wa_output.
      CLEAR wa_output.
    ENDLOOP.                           " LOOP AT i_output

Getting selected values from a data table

My data table gets values directly from a result set.
I went through http://balusc.blogspot.com/2006/06/using-datatables.html#top ,
however, the data table shown in this example takes values from a simple list. I have trouble in getting selected values.
Can anyone suggest how to select multiple values. here is a small code sample of what I have

Generating an excel sheet from an oracle table

Hi,
What is the easiest way to generate an .xls report from oracle i.e. when the user for example views some records in an oracle table using SQL_FORMS I want to then give them a button where they get a simple .xls report of the records in the table.
I have heard 'ole' method is one way, is that the best method and how is it done exactly...?
Thanks

HTMLDB 2.0 bug - tabular forms - select list from named LOV

Hi!
Changing a column in a tabular form to 'select list (named lov)' gets the following error in HTMLDB 2.0 when you try to add a row (to an empty table in my case):
PL/SQL error at column 133.
Create a table and then create a tabular form on it. Then change a report column to be a 'select list (named lov)'. Save and run the form and the error occurs.
Thanks!
Dave Venus
