Reg : SQL for fetching 10 rows incrementaly

Hi,
Version :10.2.0.
For our development purpose we need to retrive minimum (10) records incrementaly by page wise, from table which have huge volume of data (may be 1 crore).
I tried using rownum but its not efficient ...
my query :
SELECT * FROM (SELECT ROWNUM sno,*.table_name FROM table_name) WHERE sno BETWEEN 10 AND 20
In the above, the inner query fetches all the records and the records are split based on the between clause and loaded in the grid....
Is there any other efficient query or method to get this ?
Plz advice....
TIA,

Try something like this:
select *
from (
   select t.*
   , rownum rn
   from yourtable t
   where rownum <= 20
where rn >= 10;cheers,
Anthony

View the generated sql for fetching a repository item

Hi guys.
I am interested in viewing the sql that ATG framework generates to fetch a primary repository item. I would like to use this generated sql, directly on the database and avoid me the pain of having to join multiple tables to get one repository item, basically looking to avoid having to write complex sql queries to fetch information for a repository item as ATG application would view it.
I know there is a switch somewhere to turn it on, but an example would be great. Thanks!

Turn on the logging debug on for the repository.
Peace

How to fetch rows from PL/SQL table(Collections)

Hi,
I retrived rows from the table and stored in to table type.
Now I want fetch these rows and display on the screen. Pls guide me.
following code is my code:
DECLARE
type t1 is table of emp%rowtype index by binary_integer;
var1 t1;
v_counter number:=0;
BEGIN
select * bulk collect into var1 from emp;
for vr in var1.first..var1.last
loop
dbms_output.put_line(var1(1)); --Got an Error Here. Acually I don't Know how to fetch.
update dept set deptno=var1.deptno --Here also Error occured.
end loop;
END;

Fetching rows to display them is a task for the client tool. You need to define a ref cursor therefore.
If you just want to play around, here we go
SQL> DECLARE
2    type t1 is table of emp%rowtype index by binary_integer;
3    var1 t1;
4    v_counter number:=0;

7    for vr in 1..var1.count loop
8      dbms_output.put_line(var1(vr).ename);
9      update dept set deptno=var1.deptno Here also Error occured.

For each row of a table call a pl/sql function

Hi,
i have a search form in adf like this:
parameter1:___
parameter2:____
buttonSearch
Table with results
field1 field2 field3
row1 ------ --------- -------
row2 ------ --------- -------
row3 ------ --------- -------
The user inputs the parameters 1 and 2 then press buttonSearch and the query execute and returns rows 1 to 3.
What i need is for each row call pl/sql function and passed the parameter 1 and 2 and field 1 to 3 (plsql function recives 5 parameters (parameter1, parameter2, field1 , field2 and field3) )
my buttonSearch call a java class that execute ExecuteWithParamters method.
I create the call to my plsql function on Application module class and then export as a java interface.
So i have the function to use in the viewcontroller layer, but i don't know where to use it, and how to pass the paramters: the parameter 1 and 2 that user inputs and the row fields.....
any ideas....
thanks!!

Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.
Frank
Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do

SQL merge and after insert or update on ... for each row fires too often?

Hello,
there is a base table, which has a companion history table
- lets say USER_DATA & USER_DATA_HIST.
For each update on USER_DATA there has to be recorded the old condition of the USER_DATA record into the USER_DATA_HIST (insert new record)
- to have the history of changes to USER_DATA.
The first approach was to do the insert for the row trigger:
trigger user_data_tr_aiu after insert or update on user_data for each rowBut the performance was bad, because for a bulk update to USER_DATA, there have been individual inserts per records.
So i tried a trick:
Instead of doing the real insert into USER_DATA_HIST, i collect the USER_DATA_HIST data into a pl/sql collection first.
And later i do a bulk insert for the collection in the USER_DATA_HIST table with stmt trigger:
trigger user_data_tr_ra after insert or update on user_dataBut sometimes i recognize, that the list of entries saved in the pl/sql collection are more than my USER_DATA records being updated.
(BTW, for the update i use SQL merge, because it's driven by another table.)
As there is a uniq tracking_id in USER_DATA record, i could identify, that there are duplicates.
If i sort for the tracking_id and remove duplicate i get exactly the #no of records updated by the SQL merge.
So how comes, that there are duplicates?
I can try to make a sample 'sqlplus' program, but it will take some time.
But maybe somebody knows already about some issues here(?!)
- many thanks!
best regards,
Frank

How to force SQL*Loader to assign the same SYSDATE for all rows?

I want to use SQL*Loader to load some rows and a "SYSDATE" generated column, but making sure this date is THE SAME for all rows. I have seen that if I load HUNDREDS of rows there is a little difference between them (in terms of seconds). I guess it is "the moment each row entered the DB", but I need the same value for all rows (preferably, "the moment SQL*Loader was launched"). Is there any way to achieve this?
Thank you very much.

Hello user2393320.
Given some thought, using a date value to identify all records from a single load isn't very wise.
Are you able to create a procedure on the database that could be executed during SQL*Loader's execution? If so, you could develop the procedure to take in the record number of the row being loaded as an input parameter and output this unique date value for all rows loaded. The procedure would need to store the date value in a table when the first row is being loaded and return the stored date value as its output. This obviously assumes that only one sqlldr session is running at any time.
I highly recommend using a numeric sequence in the control file instead of a date to identify each file load:
, file_load_seq SEQUENCE(MAX, 1)
Another approach would be to load the record number being loaded in addition to the sysdate:
, record_number RECNUM
Hope this helps,
Luke

This code is inside a function get_emp_name(). When I execute this function I am getting the above errors. I really appreciate all your help. Please let me know if you need more information.
Thank you very much

Thank you very much damorgan,
I looked through my code and figured out what was wrong. I had a varchar2 column in the table where I was passing a value 999 instead of '999'. Thanks again.
I have one more question. I am using cursor to loop through.. here is my code
rowcount integer;
cursor c_emp is
select * from employees where empID in (....);
begin
open c_emp;
rowcount := c_emp%RowCount;
loop
end loop;
dbms_output.put_line(rowcount);
end;
I am getting rowcount = 0 even though there are many values in it. I am not sure if I am using the where clause properly. Any help would be appreciated.
thank you.

Update button in sql report for each row can only get the report value

I have to added Update for each row of records like:
select a.*,'Update' button from (
select c.*,d.login from country c,champ d
where c.champ_id=d.champ_id(+)
order by c.name) a
then go to the report->edit button ->Column Link
I added some items P40_REGION, P40_CHAMPID,P40_ACTIVE,P40_CODE and assign the value like #region#,#active# ,#code# to these item, but when I click the update button in the report I found the values such as #region#,#active# ,#code# is the report value not the select list selected value(the region, active column are displayed as select list lov).
Can anyone tell me how to sort this knid of problem?
Thanks a lot!

Sorry, it doesn't work. I also tried apex_application.g_f01(i), but not everytime I can get the value or get the incorrect value. If you have time you can try to create it like what I have described. Our team use two days now but still can not sort this problem.

Problem in fetching row code...

Hi there,
I have a bit of a problem setting up automatic row processing. The Apex processing is causing an error, but I'm not sure what PL/SQL code is being run (obviously, I don't have access to the Apex code) and all I get is the error following:
0.03: Processing point: AFTER_HEADER
0.03: ...Process "Fetch Row from VMS2_VU_VEHICLE_DETAILS": DML_FETCH_ROW (AFTER_HEADER) F|#OWNER#:VMS2_VU_VEHICLE_DETAILS:P21_ID:ID
0.05: Show ERROR page...
0.05: Performing rollback...
0.05: Processing point: AFTER_ERROR_HEADER
and then the following exception report on the page:
ORA-06550: line 1, column 17: PL/SQL: ORA-00936: missing expression ORA-06550: line 1, column 9: PL/SQL: SQL Statement ignored
Can anyone tell me how I can diagnose the problem?
please ,
Thanks in Advance
Ahmed ,

Go to apex.oracle.com, use the Request a Workspace link, submit a request, wait for approval, then import your app into your workspace.
Create a table in your workspace schema using the SQL Workshop so that you can get the same error message when you run that form page that's giving you trouble.
When you get to that point, just tell me your workspace name and application ID.

Qry return same value for a particular column for each row but not all time

hi,
We recently migrated to Oracle Database 10.2.0.3.0 from 9i. We were using a sql to populate a table and it had been running fine. After migration the same sql is fetching / population incorrect values, but not everytime. If we run the same sql again it gives a correct result.
Ex:
insert into a1 ( col1, col2, col3 )
select a.field1, b.field2, c.field
from tab1 a, tab2 b, tab3 c
where a.field = b.field
and b.field (+) = c.field
something like this. Let us assume it fetches 200 rows
But sometimes the col1 has the same value for all the 200 rows and col2, col3 has correct values. If we run the same sql next time, the col1 fetches the correct value and everything is correct.
Could someone help on the above issue.

I know it's difficult but can you put together a small test case for us to reproduce this behaviour? Did you contact Oracle Support?
Any special constructs used behind the scenes? Virtual private database? Views?Materialized Views? Anything else?

Partial locking for a row

Hello,
For example, I have two queries, the first one just accesses
the first entry of the row. And the second one just accesses the
second entry of the row.
Is there any locking method ? Such that I can lock the first
entry of the row when I use the first query and lock the second
entry of the row when I use the second query. So that I can
speed up the performance of my system in this way.
null

If you're trying to lock on a per-column basis, you won't be able
to, since locks are granular to a per-row basis, not below.
If you want to lock a specific row on a table, you may use a
2-phase commit method like so:
EXEC SQL
SELECT A.ROWID, B.ROWID, <rest of rowid's>, <rest of data>
INTO :blabla, :blabla,.....
FROM TEST_TABLE_1 A, TEST_TABLE_2 B, <rest of tables>
WHERE <where clause w/joins, etc...>
FOR UPDATE;
This will acquire row-locks on all tables referenced, for all
rows fetched by the SELECT.
This lock will be released when you close the current transaction
with a COMMIT or a ROLLBACK (or, if using from within a cursor,
when the cursor is closed if your configuration is set this way).
That means that you would:
1) Acquire the locks on all the rows
2) Do all your work using the ROWID's to locate the rows to query
or manipulate (while they're locked)
3) Commit or rollback
This will allow you to use row-level locks, which increases
concurrency and makes the SQL code a lot faster (because of the
use of rowid's).
I've found that the best method to do this is to use a cursor,
and then work on that cursor's fetches using the ROWID's (NOT the
WHERE CURRENT OF CLAUSE when there is more than one table
involved in the lock mechanism).

Raise expection for each row if returned set contains x

Hello Guys,
I have the following code and almost gave up on the idea to raise an exception and print
a line for each row where the sales price is < 10. I know how this works with a CURSOR but I want to try it without it. Thinking about it let me to the conclusion that this is not possible to act on individual row results on a set based operation. I will have to use a CURSOR (not set based so I can look at each row).
Am I thinking correctly?

Hi 3360,
I am using PL/SQL. I can make my point without any code.
The question, in a different format is this:
Can I throw an whatever exception (or dbms_output put line) for individual rows WITHOUT using a cursor.
My answer (and I just need clarification on this):
*(1)* No, because anything apart from a cursor is set-based and set-based operations (select, join, union)
can not through exceptions on individual rows.
*(2)* Yes, you can have a DBMS_OUTPUT.PUT_LINE with whatever exception on a set based operation
for each individual row that causes the exception (I dont think this answer is true :)
@Agustin UN, thanks for that. I know that is possible :) The problem is,
that I dont think I can print or fetch each individual row that causes the "exception" since
it is treated as a set. - I am welcome for someone to tell me that it work nevertheless

'Fetched Rows' refresh issue

When freezing views for several tables, the 'Fetched Rows' value is always the last updated value, not the correct one in the current context.
In the case of finding the total number of rows there is a workaround - to select from the popup menu Table > Count rows, but then, why display an incorrect value ?
And on the same 'count rows' topic, why do I need to further press the 'Apply' button in order to get the rows numbered ?
Tudor

You are right - the last fetch performed by Raptor/SQL Developer updates the fetch count on the status bar (this includes things like querying the columns when displaying a table tab).
I have suggested previously that we have the fetch count displayed next to the query execution time on the SQL Worksheet, but haven't had any positive response.
There doesn't appear to be enough room on the data tab for this to be displayed in the same place when querying table/view data from the table/view tab.
As for the 'Count Rows' needing Apply - even if you don't want to, you are given the option of copying the query that is being used for the Count Rows (not that I think this means we should have the two step process for counting rows).

Return Code - Query for Multiple Rows as XML

Hi,
I'm executing an MSSQL stored procedure through the "Query for Multiple Rows as XML" activity in LiveCycle ES. I do this through a call statement such as this:
{ call MyStoredProc(?) }
This works great, the stored procedure always returns a record set (with or without records). I use this activity rather than "Call Stored Procedure" because I can transform the record set into XML right away within this activity. Unfortunately any exception arising from invoking this stored procedure cannot be handled within the workflow as this activity does not have an exception handler (lightning bolt). In an attempt to handle at least some exceptions we have decided to use try/catches within the stored procedures and return different error codes. Now the problem I am faced with is that there is no way to retrieve the returned code within any of the SQL activities. We don't want to have to write an execute script for each of these SQL calls. Is there any way to do this? Seems like I'm 95% there.
Thanks
Nic

Thanks for the offer, unfortunately we would need something certified by Adobe.

Prompting user for input for each row in the report

Is it possible to have a user entered field for each row in a report ?
ie. have a report with empolyee number, employee name, title, salary, and comment. Select of of these columns from the SQL query except for the comment, and then when the report is generated have the user be prompted for what the want the comment to be for every employee in the report?

That is, have the user generating the report enter in a different comment for EACH employee. (ie Joe Smith's comment is "good worker and John Smith's comment is "come to work late on Tuesdays and Thursdays", Sally Jones' comment is "Expert in C++" etc.) as the reports is being built for each row returned from the query.
