How To Update two tables at once

Hi,
I have to join two tables for an update. Is it possible to update both tables in one update statement? Thank you.
UPDATE table_a a, table_b b
SET
a.name = 'Tom',
b.city = 'New York'
WHERE
a.id = b.id

Is it possible to update both tables in one update statement? That's not possible.

How to update two tables in a single call using JDBC Sender adapter

Hello All,
The scenario is, database entries have to be selected from two tables and at the same time those tables have to be udpated with the flag.
We are using JDBC sender adapter and in Select Query, we are fetching the data by joinin the two tables.
Update Statemtent: We can only update one table using this statement.
Is it possible to update two tables using the Update Statement without using Stored Procedures.
Let me know.
Regards,
Sreenivas.

Updating two tables at once

Dear all;
I have a table called using_table with the following field
using_id        life_length          Period
123                   2                   years
124                   1                   months
125                   3                   daysnow i would like a situation whenever the life_length is updated or changed to a new number for the using_table, for instance, the 2 can be changed to 200. If that is the case, this change should be reflected on another table called info_table which has a field column called expiring date. In this table, the expiring date is bascially the mfg date + life_length (period) for that particular id. For example if the mfg date is 01/01/2010 then the expiry date is 01/01/2010 + 2 years(gotten from using_table) = 01/01/2012. Another example is if the mfg date is 01/01/2011 for that id, then expiry date is 01/01/2011 + 1 month (gotten from using_table) = 02/01/2011
see details of the info_table below
info_id              using_id                 mfgdate(MM/dd/YYYY)                Expiry date(MM/DD/YYYY)
A1                       123                          01/01/2010                                    01/01/2012
A2                       124                          01/01/2011                                     02/01/2011Any help will greatly be appreciated. Thank you.

You will need 2 triggers for this. The code i am posting DOES NOT account for a multi-user environment. By this i mean if you have 2 users making concurrent modifications to this data YOU WILL get corrupted data. The only way to avoid that it to lock the tables before allowing access to them (the entire table). This means that only 1 session gets to make changes to this data at a time ... you can read about that here
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:474221407101
As an aside, since you say you are new to Oracle i will share more non-solicited advice with you.
using_id varchar2(50) not null,
info_id varchar2(100)primary key,Don't use character data types to store numeric data. It's bad for a number of reason (all of which you can also read about on AskTom).
Here's the code for the triggers and a simple test case for each.
create or replace trigger i_dont_like_doing_this
after update on using_table
for each row
begin
   update info_table i
      set i.expiry =
         case
            when :new.period = 'years'
            then
               add_months(i.mfgdate, :new.life_length * 12)
            when :new.period = 'months'
            then
               add_months(i.mfgdate, :new.life_length)
            when :new.period = 'days'
            then
               i.mfgdate + :new.life_length
         end
   where
      i.using_id = :new.using_id;
end;
create or replace trigger i_still_dont_like_this
before insert on info_table
for each row
begin
   select
      case
         when u.period = 'years'
         then
            add_months(:new.mfgdate, u.life_length * 12)
         when u.period = 'months'
         then
            add_months(:new.mfgdate, u.life_length)
         when u.period = 'days'
         then
            :new.mfgdate + u.life_length
      end

TUBBY_TUBBZ?You mentioned in another post that you will disallow modification of the EXPIRY date column by users. I don't know how you plan to enforce this, but unless you have a VERY good design methodology and lots of experience, i really don't see this happening. I'm not trying to berate you, but i remember back to when i was a beginner in Oracle (10 years ago) and that isn't something i would have been capable of.
10 years later and there's still an exorbitant amount i don't know :(

How to update two tables at the same time using jdbc

Plz will anybody tell me what is the code or query in jdbc by which you insert entry in one table and simultaneously it goes in another table?
Thanks in advance

You might be
able to design a trigger to do what you're talking
about, but that would be a database thing, not a java
thingAnother option would be an updatable view (google for usage), but it has limitations and should be used with caution. And yes, its a database thinggy and not java.
cheers,

How to insert data into two tables at once using XSJS

Hello Experts,
My requirement is to insert data into two tables at once. I have a XS JS app and want to update these tables via xsjs. How can I do this ?
Is there any mechanism like sql 'transactions' also in Hana ? If yes, how can I call it via xsjs ? If not, what are the ways to populate two different tables at once.
Please advice. Any help is really appreciated.
Thanks !

There is nothing special about inserting into two tables at once in XSJS. Just issue two separate SQL Statements. Don't execute the COMMIT until after both commands. That way they are all one transaction.

How to use one form to update two tables

How can I do that? HTMLDB wizard or form on table doesn't give me an option to use more than one table in a form or I don't know about it. I created new process which redirects the form to another page after submitting the form. On the second page I created new process which uses the same variables from the previous form page. This process runs on page load before header but it is just not working right.
So, what is the proper way to update two tables with the same form fields?

Hello Vikas,
"The Automatic Row Fetch and Automatic DML processes are a pair, you can't have one without the other."
Are you sure about that? I have a page, which populate some of the items from TableA, using manual select statement, and after the user input, save some of it in TableB, using Automatic DML. No ARF in this process and it seems to work just fine. Come to think of it, what about a simple form, populated entirely by the user input, and then being saved to the db, using Automatic DML? No ARF here also.
For the problem in hand, if you can't have more then one Automatic DML per page, I think that the simplest solution will be to define a pl/sql process, with two INSERT statement to the two different tables.
Regards,
Arie.

How to update a table containing BLOB?

Hi,
I'm trying to update two columns in a table.
one is NUMBER and the other is BLOB
Is there a way to do so in OCCI in a single operation ?
the table looks like this:
CREATE TABLE ACCUMULATORS
(TARGET_SUBS NUMBER(9),
ITERATOR NUMBER(9),
NUMERATOR NUMBER(9),
LARGE_DATA BLOB,
PRIMARY KEY(TARGET_SUBS,ITERATOR));
and the query is something like:
UPDATE ACCUMULATORS SET NUMERATOR = :x1 , LARGE_DATA = :x2 WHERE (TARGET_SUBS = :x3) AND (ITERATOR = :x4);

How to update the table value in the valuechange event?

I have an input field in the datatable with the valueChangeListener
<rich:dataTable id="cart" value="#{cart.cartList}" var="item">
<h:inputText value="#{item.cost}" id="qty" valueChangeListener="#{items.updateCost}" onchange="submit()">
<h:outputText value="#{item.errorMsg}"> </h:outputText>
in the backing bean
     Item item = (Item) model.getRowData();
// do some update, if the cost too larger, change to max_cost
     item.setCost(max_cost);
     item.setErrorMsg("Error Msg");
After calling the valuechange method, the screen output doesn't update the cost.
How to update the table value in the valuechange event?

As you're misusing the valueChangeListener to set another input field, you need to skip the update model values phase. Otherwise the value set in the valueChangeListener will be overridden by the submitted value. You can do this by calling the FacesContext#renderResponse() inside the valueChangeListener method. This will shift the current phase immediately to the render response phase, hereby skipping the update model values and invoke application phases.

How to update Spry-table and present the updated table in a div element?

Hello!
I am using a very interesting AJAX-framework called Spry when designing a web page. Here the web page is: Link.
I need some help.
Every time a new project or shift is added, the changes are written to an xml-file. When the page is reloaded, Spry reads data from xml-files.
This is caused by this code:
dsProjects = new Spry.Data.XMLDataSet("timetable/projects.xml", "projects/project");
dsShifts = new Spry.Data.XMLDataSet("timetable/{dsProjects::url}", "project/shift"); //look inside projects.xml and //extrac xml-file. url
dsName = new Spry.Data.XMLDataSet("timetable/{dsProjects::url}", "project");
I call this function that I have written: loadProjectsIntoDivElement ().
This function does the following: [See attached code.]
It iterates through the Spry-datastructure and puts the data in a table inside of the div-element called 'projectsList'.
Now, when I add a new project, I want it to be inserted into the Spry-datastructure and then cause the new data to be written into the div element called 'Specials_DIV'.
I have found out how to update a Spry-datastructure (e.g. dsProjects above), but I don't know how to update the table containing the data without refreshing the page. This should be done using Spry.
Some code:
1:
2:
3:
function loadProjectsIntoDivElement () {
$('#projectsList').html('');
$('#projectsList').append('<table id="Specials_Table"><tr><th spry:sort="id">ID</th><th spry:sort="NAME">Name </th><th spry:sort="hoursestimated">Nr. of hours estimated</th><th spry:sort="hoursworked">Nr. of hours worked</th><th spry:sort="costperhour">Cost per hour.</th></tr>{function::init_hours}<tr spry:repeat="dsProjects" onclick="chooseProject({ds_RowID})"><td>{id}</td><td>{NAME}</td><td>{hoursestimated}</td><td>{hoursworked}</td><td>{costperhour}</td></tr></table><br/>{function::get_hours}<br/>');
I have tried to accomplish this in various ways but I don't succeed.
I want to do it without refreshing the page.
Update: I found some code here that I will try: Link
Thanks in advance!
Anders Branderud
My blog

Hello!
Thanks!
I don't succeed with the implementation in any browser.
I have found a way to it, but I would like a way that updates the data quicker and without reloading all of the page. After all, I am only adding one row on the end of the data structure, so there should be no need to read in all data again.
Now I do it like this:
When a project is added, do this:
1. Store a new row in the project file through a php script.
2. When the post-call to the php-file returns, do refresh of the whole page.
Then the newest version of the xml file will be read in.
However, I don't want to read the data from a xml file each time that a new project is created.
I know how to add the new data to a Spry-datastructure [in my code 'dsProjects'], but I don't know how to display the updated data without reloading the whole page.
I have tried some various ways to do it, but haven't succeded.
Thanks!

Can you really update two tables in one SQL statement

Ok a post in the forum has got me awefully curious:
Can you update two tables in one update statement i.e something like this
update table a , b
set b.<column> = something
a.<column> = something
Something to this effect.
If you are curious to know what post I am talking about it is called "updating a single row"

No. You can only update one table in one SQL statement.
