Updating a row of table.

Hi,
I have a requirement in which, there is a table with say 5 columns and each column is an outputtext except the last 1. The last 1 has both outputtex and commandlink under it. The requirement is, when I click the command link of a particular row, it should display a symbol like * in the output text of that row and that column only. I have tried few methods but it is setting the output text of all the rows of that column to *.
Please help me in this regard.
Thanq.

First make it clear: analyze table command never changes ROWIDs. Actually, the ROWID of a row never changes untill it's deleted from its table. So make sure if you are using the correct ROWID.
Thnx

How to update duplicate row from table

Hi,
how to update duplicate row from table?
First to find duplicate row then update duplicate row with no to that duplicate row in oracle.
can you give me suggestion on it?
Thanks in advance.
your early response is appreciated...

In order to find a duplicate row, see:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1224636375004
(or search this forum, your question has been asked before)
In order to update it, just create and use an Oracle sequence, have it start and increment at a value that doesn't exist in your table.
If that doesn't get you going, post some CREATE TABLE + INSERT INTO statements, and the results you want from them, in other words: a complete testcase.

Updating certain rows of table by external file??

Hello gentlemen,
I need your help.I have a very large table.I need to update certain rows of table every day(around 200 per day)
I would like by using an external file (.csv or .txt) to update certain column on the 200 rows i have in the external file.
Can this be done?Do i need to write down a pl/sql procedure?Please help.I am a newbie to pl/sql but it will save me much time every day if i manage to do this.
Thank you in advance for your help.

I made a first attempt to create the external table from a .txt file.
I used the below:
CREATE TABLE pol_test
(STATUS VARCHAR2(30 CHAR),
ASFAL VARCHAR2(20 CHAR)
ORGANIZATION EXTERNAL
(TYPE ORACLE_LOADER
DEFAULT DIRECTORY def_dir1
ACCESS PARAMETERS
(RECORDS DELIMITED BY STRING
FIELDS (STATUS VARCHAR2(30 CHAR),
ASFAL VARCHAR2(20 CHAR)
LOCATION ('C:\Users\t.christopoulos\Desktop\TEST.TXT')
I get the below error :
Error report:
SQL Error: ORA-06564: object DEF_DIR1 does not exist
06564. 00000 - "object %s does not exist"
*Cause: The named object could not be found. Either it does not exist
or you do not have permission to access it.
*Action: Create the object or get permission to access it.
I suppose that it goes to create the directory on the server where i dont have access.I run these commands from my desktop using SQL developer.

Problem to update 16 rows, it updates all rows in table

I tried to update 16 rows with AL as divion name with the script as below:
Update wire_center a set a.wg_id='63'
where EXISTS (select b.div_name from wire_center a, division b, district c, ns_workgroups d
where B.DIV_NAME='AL' AND a.dis_id=c.dis_id and b.div_id=c.div_id and d.wg_id=a.wg_id );
When I run it, it updates all the rows in the table.
However when I run the select subquery, it returns 16 rows.
It seems where EXISTS is the problem. if I take exists out, it gave me ora-00936 error.
How to fix it? Please need urgent help. db is 10g.
Thanks in advance.

If I understand correctly what you want, you should not include wire_center again in the second select (in your exists clause).
The second select has no relation to the table you are updating, so because the second select returns 16 rows, the exists will always be true. For every row. So every row will be updated.
Instead of
Update wire_center a set a.wg_id='63'
where EXISTS (select b.div_name from wire_center a, division b, district c, ns_workgroups d
where B.DIV_NAME='AL' AND a.dis_id=c.dis_id and b.div_id=c.div_id and d.wg_id=a.wg_id );try this:
Update wire_center a set a.wg_id='63'
where EXISTS (select b.div_name from division b, district c, ns_workgroups d
where B.DIV_NAME='AL' AND a.dis_id=c.dis_id and b.div_id=c.div_id and d.wg_id=a.wg_id );Edited by: theoa on 29-dec-2010 14:27

Updating a row in table exclusive lock on entire table

Hi
We have table master table and few child tables .
when we try to update a row in master table , it is locking entire table
i.e seems update process holding exclusive lock on entire table
it is not allowing any furthur update to that table
Could you please tell me what could be the problem for that
Thanks,

Does the table has primary key - foreign key relationship? Try disabling the constraint and see if it works. If it works then it is about unindexed foreign key issue.

Trouble updating multiple rows in table using subquery

Hi everyone, I'm having trouble updating multiple rows with a subquery. Here's the setup:
create table mytable (
col_a number primary key,
col_b number,
col_c number,
col_d number);
insert into mytable values (1 ,1,1,15);
insert into mytable values (2 ,1,2,7 );
insert into mytable values (3 ,1,3,11);
insert into mytable values (4 ,1,4,23);
insert into mytable values (5 ,1,5,14);
insert into mytable values (6 ,2,1,50);
insert into mytable values (7 ,2,2,41);
insert into mytable values (8 ,2,3,13);
insert into mytable values (9 ,2,4,12);
insert into mytable values (10,2,5,19);
insert into mytable values (11,3,1,10);
insert into mytable values (12,3,2,92);
insert into mytable values (13,3,3,81);
insert into mytable values (14,3,4,17);
insert into mytable values (15,3,5,66);
insert into mytable values (16,4,1,54);
insert into mytable values (17,4,2,41);
insert into mytable values (18,4,3,22);
insert into mytable values (19,4,4,24);
insert into mytable values (20,4,5,17);For this example, using an update statement (or merge if that's better), say I want to set the values for col_d where col_b = 3 equal to the values for col_d where col_b = 1 and col_c equal each other. Results should look like the following after the update:
col_a col_b col_c col_d
1     1     1     15
2     1     2     7
3     1     3     11
4     1     4     23
5     1     5     14
6     2     1     50
7     2     2     41
8     2     3     13
9     2     4     12

15    3     5     14
16    4     1     54
17    4     2     41
18    4     3     22
19    4     4     24
20    4     5     17I can see it right there at my fingertips using this query, where I want to set b_col_d = a_col_d, but I'm missing something, as this query returns too many rows when used in the update statement.
select * from (
select col_a as a_col_a, col_b as a_col_b, col_c as a_col_c, col_d as a_col_d
from mytable
where col_b = 1
) a, (
select col_a as b_col_a, col_b as b_col_b, col_c as b_col_c, col_d as b_col_d
from mytable
where col_b = 3
) b
where a.a_col_c = b.b_col_cupdate mytable set column_d = (select ??? where exists ???)
Can someone help me get there? I'm using 10GR2.
Thanks!

/Note the following:
1. I've turned the code into a package, rather than a standalone procedure - this allows you to group related procedures/functions together, and also control whether they're private or public functions/procedures.
2. I've moved the exception definitions to the package spec; this allows the rest of the world to access these exceptions - handy for if you're checking for specific error conditions from outside the package (eg. the proc which calls flight_pkg.flight).
3. I've merged the two SELECT statements together, rather than UNION them; this should improve performance as now only one tablescan is required, rather than two as previously. Is the statement correct, though? It would appear that the destination is unconstrained in both sets of conditions, therefore you are selecting all flights leaving from the origin or the destination, rather than just those going between the two on the given dates. This doesn't appear to match what you're doing in the first half of the flight procedure!
4. I've combined some of the conditions for your IF statements - not strictly necessary, but I think it makes the code more readable and therefore maintainable.
5. I've modularised the code by taking out the checking the outbound/inbound availability, and putting the code into its own procedure. There is only one set of code now to do the checking, rather than two as before - but the new procedure is called twice with the appropriate parameters. This is good coding practice - you now have only one bit of code to maintain, rather than two identical bits! It's also a lot more readable.
6. I've converted your cursor into an INSERT INTO ... SELECT ... statement - it's better to have one SQL statement than loop row-by-row (aka slow-by-slow).
7. I've removed most of your comments, as they were a bit pointless... "Truncate table" when you're following it with a command that says "Truncate table"? Most of the code should be self-documenting - especially if you choose decent names for your variables, procedures, functions, etc. Don't use comments to describe what the code is doing, describe why it's doing it. You should go through the code and make sure your identifiers have meaningful names.
Hopefully you can see that what I've done has a) made things easier to read and maintain and b) more performant.

Update multiple rows in table using ODataModel.

I have tied ODataModel with table using "TwoWay" binding. I need to allow user to edit the rows of the table at the bottom of which I have 'Save' button. Currently though the table is editable I am unable to edit the entries in multiple rows of the table.
Please find my code below:

Is there something pending in the settings? And to update the multiple records in the table do I have to make use of some batch operations? Any help would be appreciated.

Hi Supriya,
your code is missing call of oModel.submitChanges() when Save button is called.
You can find the example here SAPUI5 SDK - Demo Kit

How can I update multiple rows in table using a single form button and checkboxes

I have a project where the visitors can select multiple productos and once the click on the PURCHAS button it updates the selected records.

You have not mentioned the programming language that you are using, but here's a link that could help you if you are using ASP.

Who updated the Row in Table

Hi Experts,
I wants to enable tracking for one of the table in my database.Tracking details must contains Time,new values ,old values and more importantly who/when made the changes.
Other than Triggers do we have any other way to track those changes.
Suggestions are highly appreciated.
Thanks,
Nandhu

Hi NandhuJana,
Please check my response above. I already gave the basic logic there. If you need the "who" then this is manually work, as CDC isn't designed for auditing but for data change tracking. Next step is to write the code for you, and for this
we need the DDL+DML and the CDC information (all element that it created for you),
but on the same time i recommended above
NOT to use CDC if you need the "who" information. The "when" is built-in in CDC and you can check the URL that I posted above for this.
I write again my recommendation here as I wrote above from what I assume is best for your case to lower:
1. create your own DML triggers on the tables (probably best solution in your case, if I understand it correctly)
2. Use Extended event or profiler (I don't like this solution for this case if this is permanent tracking)
3. Using OUTPUT in each query (need to change all query and not fit for most cases, but i some cases it is the best solution)
*** If you can post for us the table DDL for the table that you want to track, then we could help you with the
trigger. but first make sure that you understand the idea and you know what are
triggers :-)

How to Update Particular row in a table from OAF page

Hi Can anyone please help me on the following requirement:
In my oaf page i am displaying table values(supplier site details from base tables) with update and delete icons . When i click on update button a new page opens in which we used to update the values and click on apply button which again comes back to the original page.
So when i click on apply button on update page i have to first search for the site in the site table whether it exists or not, if not exists i have to create a new row and save the data, if site exists in the table i have to update the row of a table for that particular site. I have written code for this but unable to achive the requirement, it is not updating the existing row of the table. And i am doing all this on the Temp tables.
So now when i save, previous transaction is also updating along with the current transaction. That means when i m trying to save 2nd transaction values , 1st transactions values are getting updated with the 2nd transaction values(2 rows are getting updated)
Can anyone help me with the code used for updating the current row of the table. Please correct me if i m doing anyting wrong in code.
following is the current code i m using and which is failing :
Controller Code
if(pcontactaction.equals("createECdetailsEvent")) {
String currentSiteName=pageContext.getParameter("SiteName");
System.out.println("Selected Site Name is : " + currentSiteName);

System.out.println("Invoking AM Method.........");
am.invokeMethod("initCreateECDetails",x);

break;
catch (Exception e) {
System.out.println("Exception in update : " + e);
}

Please answer following:
1. Are you using EO based VOs or ReadOnly VO?
2. What is your VO Query for the search and update?
3. Why have you based your logic on site_name; you should have used site_id?
4.Are you getting correct site name in handling createECdetailsEvent event in CO?
5. In case of update are you getting correct values on the Update Site Details?
6. On coming back from Update page to Supplier Site Search page, do you see old values of the site or the new values in the results table?
Please share the screenshot if possible.

Need help in SQL Query: Update a row in a table & insert the same row into another table

I want to update a row in a table say Table A and the updated row should be inserted into another table say Table B. I need to do it in a single SQL query and i don't want to do it in PL/SQL with triggers. And i tried with MERGE statement but its working with this scenario. (Note: I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.1.0).
Thanks in Advance.

Using Sven's code as an example, you could save the updated row in a sql plus variable. (also untested):
SQL> var v_id number
update tableA
set colB='ABC'
where colC='XYZ'
returning id into :v_id;
insert into table A_History (ID, colA, colB, ColC)
select id, ColA, ColB, ColC
from tableA
where id = :v_id;

A standard disclaimer, the mutating trigger error is telling you that you really, really, really don't want to be doing this. It generally indicates a major data model problem when you find yourself in a situation where the data in one row of a table depends on the data in another row of that same table. In the vast majority of cases, you're far better off fixing the data model than in working around the problem.
If you are absolutely sure that you cannot fix the data model and must work around the problem, you'll need
- A package with a collection (or global temporary table) to store the keys that are modified
- A before statement trigger that initializes the collection
- A row-level trigger that adds the keys that were updated to the collection
- An after statement trigger that iterates over the data in the collection and updates whatever rows need to be updated.
If you're on 11g, this can be simplified somewhat by using a compound trigger with separate before statement, row-level, and after statement sections.
Obviously, though, this is a substantial increase in complexity over the single trigger you have here. That's one of the reasons that it's generally a bad idea to work around mutating table exceptions.

All i want is that when users click on SUBMIT button values of point column in s_lessons(database table) be updated by new entries from user.
i did my best and result with that code is :
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' lid=888, sid=860935422, term=902' at line 1
I would appreciate any idea.
with prior thanks

Go to the Row Properties, and in the Visibility tab, you have "Show or hide based on an expression". You can use this to write an expression that resolves to true if the row should be hidden, false otherwise.
Additionally, in the Matrix properties you should take a look at the filters section, perhaps you can achieve what you wish to achieve through there by removing the unnecessary rows instead of just hiding them.
It's only so much I can help you with the limited information. If you require further help, please provide us with more information such as what data are you displaying, what's the criteria to hiding rows, etc...

Update all rows in a table which has 8-10 million rows take for ever

Hi All,
Greetings!
I have to update 8million rows on a table. Basically have to reset the batch_id with the current batch number. it contains 8-10 million rows and i have tried with bulk update and then also it takes long time. below is the table structure
sales_stg (it has composite key of product,upc and market)
=======
product_id
upc
market_id
batch_id
process_status
I have to update batch_id,process_status to current batch_id (a number) and process_status as zero. I have to update all the rows with these values for batch_id = 0.
I tried bulk update an it takes more than 2hrs to do. (I limit the update to 1000).
Any help in this regard.
Naveen.

The fastest way will probably be to not use a select loop but a direct update like in William's example. The main downside is if you do too many rows you risk filling up your rollback/undo; to keep things as simple as possible I wouldn't do batching except for this. Also, we did some insert timings a few years ago on 9iR1 and found that the performance curve on frequent commits started to level off after 4K rows (fewer commits were still better) so you could see how performance improves by performing fewer commits if that's an issue.
The other thing you could consider if you have the license is using the parallel query option.

Updating a row of table.
