Selecting only required number of rows in an external table

Hi,
I have an external table with many flat files as source.. I know I can skip rows using the keyword 'SKIP'. I want to select only first 'n' rows from all the flat files as the rows available in my oracle external table. Is this Possible?...
eg..
Flat file 1
c1,c2
123,45
132,56
'ahgh',34
'dfd',22
Flat file 2
c1,c2
56,1212
545,45
'ahcsd',4
'dds',24
I want to create a file which contains the rows, means only the 2nd and 3rd rows from each flat files
123,45
132,56
56,1212
545,45
Thanks in Advance

If this means selecting from all these flat files at the same time then it might get a bit cumbersome. Basically you will have to create an external table for each flat file and then do something like this:
SELECT * FROM
( select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_1 )
    where rn in (2, 3)
   union all
    select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_2 )
    where rn in (2, 3)
   union all
select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_3 )
    where rn in (2, 3)
   union all

XMLIndex: finding indexed XPaths and the number of rows in the path table

Hi,
I am storing non-schema-based binary XMLs in an XMLType column in 11g (11.1.0.6.0) and would like to index the XMLs either partially or fully using XMLIndex. I'm expecting to have a large number (tens of millions) of XML documents and have some concerns about the size of the XMLIndex path table.
In short, I am worried that the path table might grow unmanageable large. In order to avoid this and to plan for table partitioning, I would like to create a report of all indexed XPaths in an XMLIndex and to find out how many times each path is actualized in the path table. I would do this for a representative XML sample.
I have been creating XMLIndexes with different exclude/include paths, gathering stats with DBMS_STATS (estimate_percent = 100) and selecting the number of rows in the path table through USER_TABLES.
If anyone knows a more straightforward way of doing this all advice is very much appreciated.
Best Regards,
Rasko Leinonen

Thanks Marco,
I managed to get out all indexed paths using the following SQL. It took a while to understand how the join the XDB.X$PT39CW6BJR8W4VVE0G0LLGA0OCR5 and XDB.X$QN39CW6BJR8W4VVE0G0LLGA0OCR5 tables together but got there in the end. This helps to clarify which XPaths are being currently indexed by the XMLIndex.
begin
for v_row in (select PATH from XDB.X$PT39CW6BJR8W4VVE0G0LLGA0OCR5)
loop
declare
v_i BINARY_INTEGER := 1;
v_id raw(8);
v_len BINARY_INTEGER := 2;
v_skip BINARY_INTEGER := 1;
begin
while v_i < utl_raw.length(v_row.path) and
v_i + v_len <= utl_raw.length(v_row.path)
loop
v_i := v_i + v_skip;
v_id := utl_raw.substr(v_row.path, v_i, v_len);
--dbms_output.put_line(v_id);
for v_row2 in (select LOCALNAME, flags from XDB.X$QN39CW6BJR8W4VVE0G0LLGA0OCR5
where ID = v_id )
loop
if rawtohex(v_row2.flags) = '01'
then
dbms_output.put('@');
end if;
dbms_output.put(v_row2.localname);
if v_i + v_len < utl_raw.length(v_row.path)
then
dbms_output.put('/');
end if;
end loop;
v_i := v_i + v_len;
end loop;
dbms_output.put_line('');
end;
end loop;
end;
Example output:

Resukt:Get number of rows from 3 different table...?

Hi All,
I need to find out number of rows from 3 different table for the same conditions. Instead of writing 3 queries, is it possible to get it thru one query?
For example, i need to find out number of rows in tables where name = 'Ameet' from 3 different table, i will end writing 3 queries.
1. select count(1) from table_a where name = 'Ameet';
1. select count(1) from table_b where name = 'Ameet';
1. select count(1) from table_c where name = 'Ameet';
Is it possible to write a single query to get result of all above 3 queries?
result:
table_a table_b table_c
34 44 2

One way:
SELECT      (SELECT     COUNT(*) AS CNT FROM TABLE_A WHERE name='Ameet') AS TABLE_A
,     (SELECT     COUNT(*) AS CNT FROM TABLE_B WHERE name='Ameet') AS TABLE_B
,     (SELECT     COUNT(*) AS CNT FROM TABLE_C WHERE name='Ameet') AS TABLE_C
FROM DUALIf you want the total:
SELECT     SUM(CNT)
FROM
     SELECT     COUNT(*) AS CNT FROM TABLE_A WHERE name='Ameet'
     UNION ALL
     SELECT     COUNT(*) FROM TABLE_B WHERE name='Ameet'
     UNION ALL
     SELECT     COUNT(*) FROM TABLE_C WHERE name='Ameet'
)

Select a specific number of rows in query

How can a specific number of rows be selected in a query? For example, a query retrieves 30,000 records and I want to retrieve the output by groups of 5,000. I want the query to retrieve the first 5,000 records, then the next 5,000 records etc. I tried rownum but that does not work.

How to restrict number of row/lines in a table in RTF

Hi,
Im working on PO report. It has header information in the header part of RTF. But coming to the lines , I put that under a different group in the table in the body part of the RTF. I did a FOR loop for printing PO Lines because it does have multiple line information. But now i have to restrict the number of rows in that table per page irrespective of number of PO Lines. After printing 20 rows in the table, it should go to the next page. Im going through the other threads for the solution.
Thanks,
venkat

There are so many thread regarding this ,
pls go thru them patiently...
logic is something like....
use if condition and position() and say page-break..
use for-each@section instead of for-each..so that the headed info is maintained with regards to PO lines
happy searching...
if you cant get still, last option send me mail with details

How to get the number of rows in a HTML table in some other page

Hi,
I am incrementing HTML table rows on button click and saving number of rows in a javascript variable. But on submitting that page I need that number of row value in the following page
example:
HTML table is in the page first.jsp
and the javascript variable having the current row number is row_number
on submitting it goes to second.jsp page. There i need that row_number value.
Can anyone help me to solve this?
regards,
carry

function buttonClick()
var table = profileTable;
var lnRow = table.rows.length;
var insertedRow = table.insertRow(parseFloat(lnRow));
var cell1 = insertedRow.insertCell();
cell1.innerHTML ="<tr><td><Input type=\"hidden\" >>>name=\"rowNum\" value="+cnt"+></td></tr>";
document.profileform.submit;
on submit it goes to the second page, but the value i got using >>>System.out.println("row number from text >>>box"+request.getParameter("rowNum")); is null. What is wrong with >>>my coding. Can anyone solve this.HI carry
Check the value of bold data
function buttonClick()
var table = profileTable;
var lnRow = table.rows.length;
var insertedRow = table.insertRow(parseFloat(lnRow));var cnt=inRow
var cell1 = insertedRow.insertCell();

HOW TO SELECT ONLY THOSE RECORDS WHERE NOT AVAILABLE ON SECOND TABLE

hi
i have two tables one name is menus and second name is UGroupDetail. Actually i have created it for user role privileges for my application

UGroupDetail have many groups as assigned to a new user but Menus table has only default groups which is 90 records
Menus table is a primary table and UGroupDetail is a Foreign key table
now i want to combined these tables and want to get only remaining records for each group
for example i have assigned 5 roles to GroupID 2 and now when i apply select commands the result should be 85 out 90 for GroupID 2
but i have not idea how to modify select query for get desired result

I don't really understand the tables. What is GroupID doing in the Menues table? And what does an entry without a RightName mean? Shouldn't that column be NOT NULL?
The UGroupDetail does not have any primary key. From your description, I would expect the PK to be (RightID, GroupID). But strangely enough, GroupID is nullable. So is RightName, but I think this column is redundant and should be removed.
Anyway, if I understand your question correctly, you need something like:
SELECT UG.Name, M.RightName
FROM   UserGroups UG
CROSS JOIN Menus M
WHERE NOT EXISTS (SELECT *
   FROM   UGroupDetail UGD
   WHERE UG.GroupID = UGD.GroupID
   AND UG.RightID = M.RightID)

Updating a field for a number of forms from an external table

Good Day All;
This one I could not find in the help section.
I have designed a number of forms that all use the same “rates of pay” (there are 4 categories) for calculating. I was told to expect that a few more forms will be required and these new forms will also be using the same “rates of pay”
Currently I am using “switch” to insert the “rates of pay” when the user selects a category from a dropdown.
Is there a way I can update all the forms from an external “table” instead of having to update each form individually?
Thanks All
Chomp

Hi,
If the form is Reader enabled with Acrobat, then that is going to cut out data connectons.
You should have a look at John Brinkman's blog: http://blogs.adobe.com/formfeed/2010/07/shared_data_in_packages_part_2.html. Two parts.
Also there is an example of inter-form communication here, but it may be too clunky: http://assure.ly/qQivbm.
Good luck,
Niall

Dynamic Select with different number of rows

Hi all,
I have a procedure who receives a table name and array of column names of that table.
I need to create a specific select statement with this parameters. Of course, this could change because the number of column names may differ from each invocation the this procedure.
Here's my procedure:

Adding Favorites selects only mobil number

Using iOS 7.0.4 I am trying to add Favorites to the phone app. No matter which phone number I select, the app always saves the MOBILE phone number in Favorites (if there is a mobile phone number associated with the selected contact). How can I save e.g. the WORK PHONE in Favorites?

You could enter the contact twice, once with the mobile and once with the other number and favourite both

URGENT: Selecting only 25 records at a time from a table

URGENT !!!!
Hi,
Im having a RFC which selects records from a table (say table_A) and depending on these selected records, further processing is done within that RFC.
Now my problem is, this table_A contains around 200 matching records. Due to this entire logical processing consumes lot of time. Hence my RFC is taking huge time to produce result. (apprx 10 mins).
Can i select these matching records in batch of 25 and display result for these 25 records??
I'll give this batch size as input to RFC?
Do anybody have any idea about how to tackle this situation and reduce response time?
If u hav any better solution than this then pls pls let me know ASAP..
Regards,
Amey

Amey Mogare ,
Do One thing , create a new importing parameter in your RFC , say current_trans_id. NOw on the first call pass the initial value for current_trans_id.
then inside the logic .. change the select to
select upto 25 rows where trnascation id > current_trans_id.
next time when u call teh rfc.. send the last selected id as a value for current_trans_id.
i think you can some how use this logic

Why would an Oracle synonym return a different number of rows to the underlying table?

Hi, I was doing some queries in EBS to extract data and I realized I was missing a lot of data.
After investigating I realized:
select count(*) from apps.XLA_TRANSACTION_ENTITIES;
35459
select count(*) from xla.XLA_TRANSACTION_ENTITIES;
1122337
The apps.XLA_TRANSACTION_ENTITIES is a synonym for xla.XLA_TRANSACTION_ENTITIES.
The synonym creation code is:
CREATE OR REPLACE SYNONYM "APPS"."XLA_TRANSACTION_ENTITIES" FOR "XLA"."XLA_TRANSACTION_ENTITIES";
I've check and there is a dba_policy applied. The predicate is 1 = 1.
With this predicate shouldn't all the rows be retrieved? What else can be filtering the rows retrieved in the synonym?
The database version is: Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
Thank you,
Carla

Carla,
This is how we find the answer to your question, so maybe this would save you time next time
- Login to MOS website
- Search for XLA_TRANSACTION_ENTITIES AND SYNONYM
- You will see (Why are there differences in SELECT * FROM XLA_TRANSACTION_ENTITIES and SELECT * FROM XLA.XLA_TRANSACTION_ENTITIES ? (Doc ID 946314.1)) second in the list
Thanks,
Hussein

Find out number of rows of an ALV table

I would like to implement a generic method that returns the number of lines that are shown in an ALV table. Is this possible? Can I retrieve this information from the ALV model, or do I have to check the context for this?

Hi Daniel,
The iwci_salv_wd_table interface (the interface used which implements the method GET_MODEL), also has the method WD_GET_API, which returns a reference to IF_WD_CONTROLLER. This interface implements methods which will return the context information.
Hope this helps

Wenonah

Oracle database link to MySQL select only one row

Hello,
I have created a connection from the Oracle batabase 11.2 to a MySQL database via database link. The following statement shows, that 35 rows are in the mySQL table:
SQL> select count(*) from "main_pages"@MOREWEB;
COUNT(*)
        35
But a normal select statement only return 1 row.
SQL> select "subject" from "main_pages"@MOREWEB;
subject

I am using the mysql-connector-odbc-3.51.30-winx64 driver. A newer version cann't be installed because on Windows Server 2008 R2 I get an error with an missing dll-file. The DataDirect-ODBC-driver is not possible, because we like to use the free MySQL-database an DataDirect only support the enterprise edition.
I also have tried to limit the HS_OPEN_CURSORS or dont limit the HS_FDS_FETCH_ROWS, but there is no difference in the result. I always get only one row.

Bianca,
If you log directly into MySQL and issue the same query (select "subject" from "main_pages";) what data is returned?
I looks to me that you count is the number of rows in the entire table "main_pages"
while you select is for the data in the "subject" column only.
This seems to indicate that you have just one row in that subject column.

WHAATT?
What do you mean by "just one row in that subject column"?
That makes no sense at all. A row is a row. A column is a part of a row. All rows have all columns, though not all columns of all rows will necessarily have an assigned value. Lacking a WHERE clause to filter rows, any SELECT should return all rows.

Selecting only required number of rows in an external table
