Update the value Table B if table A the value of different
Hi allI'm using Toad for Oracle and need assistance with a trigger. I have two tables tables A and B Table with some of the same fields. I want to only update the values in the array B, if the values in table A are not equal values in table B table A update. Don't update the record where the primary key of the Table equal to the foreign key in the Table B. I have a sample script below, I hope someone can give me an example, I can develop and test. Thanks for reading also.
CREATE OR REPLACE TRIGGER AU_Table_A
AFTER UPDATE ON Table_A
FOR EACH ROW
BEGIN
If Table A :old.value != Table A :new.value
then
update
--Update Table B value with Table A updated value
Table B :old.value = Table A :new.value
where Table A primary key = Table B foreign key
............
END IF;
END;

Hi Nikki,
If I understand correctly, then maybe
create or replace trigger au_table_a
after update
on table_a
for each row
when (old.value != new.value)
begin
update table_b
set table_b.value = :new.value
where table_b.foreign_key = :new.primary_key
and table_b.value != :new.value;
end au_table_a;
/
Note that the solution is not trying to handle NULL values. If you have NULL in to either A or B, we have to manage those specifically
Concerning

Is Toshiba supports a utility to update the BIOS like DCCU?
Hi all
Another laptop to the manufacturer use a utility called the Configuration utility (DCCU) Client that can be used to update the BIOS for several models of laptops in the series.
I searched on the web and these forums, but I can't find a similar tool for Toshiba laptops.
Can someone point me in the right direction please?
Thank you

Hello
You should not compare the procedure of updating the BIOS from different manufacturers with the process of updating the BIOS Toshiba laptop.
Laptop Toshiba computers come with special versions of BIOS (Toshiba & Phoenix) and on the update of the procedure is also different!If you want to update the BIOS of Toshiba laptop, you will need to first check if a new BIOS is available and you should check the statement and the update process.
If I m not mistaken not updated the BIOS most on the most recent series portable Tosh must be done of Windows operating system.If an update BIOS utility like DCCU is unavailable for Toshiba laptops!
Best regards

Update the values in the Table from another Table containing historical data
So, I have two tables, a table and a master table. The current table is updated each week and at the end of the week, is copied to the main table to keep historical data. I have update the table in progress early in the week and want to take the latest data from the master table and update the current table with the data. The current table could have additional IDs or some of the IDS could have deposited (these lines would receive data in the main table). I want to only update the rows in the current table that have existing data to the attr1, attr2, attr3 columns. A particular ID may have more than one record in the primary table, I want only the last disk to use for updating the current table. The data from a different database where no direct connection is possible then I have to import data every week. Here are some statements of create/insert:
create table current_T (ID1 varchar(100),adate date,attr1 varchar(100),attr2 varchar(100),attr3 varchar(100))
create table Master_T (ID1 varchar(100),adate date,attr1 varchar(100),attr2 varchar(100),attr3 varchar(100))
begin insert into current_T (ID1,adate) values ('IE111','08/02/13'); insert into current_T (ID1,adate) values ('IE112','08/02/13'); insert into current_T (ID1,adate) values ('IE113','08/02/13'); insert into master_T (ID1,adate,attr1,attr2,attr3) values ('IE111','08/01/13','yes','abc','123'); insert into master_T (ID1,adate,attr1,attr2,attr3) values ('IE112','08/01/13','no','dgf','951'); insert into master_T (ID1,adate,attr1,attr2,attr3) values ('IE113','08/01/13','no','dgf','951'); insert into master_T (ID1,adate,attr1,attr2,attr3) values ('IE113','07/01/13','no','dgf','951'); end;

I have a tabular form and I want to update the value of a field using a process based on an add-on.
the name of the column in the form of tables is (name of column P22_PROJECT_ID)
The error I get is

Error unexpected, unable to find the name of the option at the page or application level.
The field is questioned as

I also tried without the colon (P22_PROJECT_ID), but the application does not recognize.
Any help would be appreciated.

Best way to update the individual rows of a Table?
I took a quick glance at a few examples, but did not get a clarification on this. I am looking to have something close to a listbox control or the table to where I can update just one column of values to line a 1 time per second pace. I'm looking to display our acquisition of data values in a table or a listbox control. The single list box seemed to work well for that, but I couldn't use the row headers to list the names of channel beside the channel values. I thought to link the values of cursor in two areas of list to do this, but did not find any info on it for the single list box.
I have a few questions:
(1) I have a 1 d table to where I want to use this data to constantly update the first column (with a multitude of lines) of a table. I'm looking for the best route to not take too much time for treatment by doing this.
What is the best way to update the individual rows of a table? Invoke the node "Value of the cell value"... or is there another method?
(2) why is that, after each iteration else, row values are deleted?
Also, for adding additional channels originally arrray... it is better to use the 'Array' subset then the function "Construct the table" or function "Subset of the table" and "insert table"?
See the attached example.
Thank you.
Jeff· Þ· Bohrer says:
(2) why is that, after each iteration else, row values are deleted?
Classic race condition. dump the loop and node-p and just wire the 2D table on the terminal Board. !
I don't see the race condition. What I see is the table once the last element has been written for it all run the oil. I saw looked it with point culminating performance on.
But I agree entirely with writing to the Terminal. It is a 1 d array, so you will need to use an array of generation and convert a 2D array in order so that he could write correctly.

Select the data in a table and update in another table
Dear experts,
create the table TB_ENCRYPT
(
Identification number,
Varchar2 (200) KEY
);
INSERT INTO TB_ENCRYPT VALUES(1,'HJUVHDUIFBSDGVU');
SELECT * FROM TB_ENCRYPT;
1 HJUVHDUIFBSDGVU
create TABLE users)
username, NUMBER of
password VARCHAR2 (200)
);
Insert users
values (1, 123 # "")
Insert users
values (2, 456 #')
Select * from users;
1 123 #.
# 2 456
I want to select the data KEY for table TB_ENCRYPT column and update in the column of tables for the respective key user password
TB_ENCRYPT table contains only a single key value. Comparing this key, I want to update the old value of the key to the new value.
For encryption and decryption I followed the java class method.no is worried about that.
create or replace
PACKAGE PCK_ENC AUTHID CURRENT_USER AS
FUNCTION DECRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.decrypt (java.lang.String, java.lang.String) return java.lang.String ';
FUNCTION ENCRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.encrypt (java.lang.String, java.lang.String) return java.lang.String ';
END;
SELECT PCK_ENC. ENCRYPT('1234','HJUVHDUIFBSDGVU') FROM DUAL;
HERE,
1234 - is the password of the users table column data
HJUVHDUIFBSDGVU - represents the key of table TB_ENCRYPT column data.
Comparing this key, I want to update the old value of the key to the new value.
I tried with this method
declare
cursor c1 is
Select the key
of TB_ENCRYPT
where id = 1
update the id;
Start
for c1_rec looping c1
update users
password is PCK_ENC. Encrypt (Password, Key)
the location being c1;
commit;
end loop;
end;
/
Help, please
You can use the MERGE statement.
merge into users using tb_encrypt on (id = userid) when matched then update set password = PCK_ENC.ENCRYPT(password,key);
And why you encrypt your password. This isn't a good idea. Just password hash.

APEX: Update the table fields
I am in dilemma here.
I have a table as a table for the fields in this example two, a field is 'LASTMODIFIED' date and the other
field, "Q1" where the user can be updated when necessary.
"I have used trigger, so whenever the user updates the Q1, the ' LASTMODIFIED ' is updated to the last sysdate.
This method works.
"But during my UAT, I realized that if the"Q1"is null, the ' LASTMODIFIED ' will not update, until
There is a value.
I tried to tweak the trigger by checking if it has the value zero.
create or replace TRIGGER "my_table_BIU_TRG".
BEFORE THE INSERT OR UPDATE
ON my table
FOR EACH LINE
BEGIN
If
: NEW. Q1! =: OLD. Q1 or
: OLD. Q1 = null
then
: NEW. LASTMODIFIED: = SYSDATE;

END;
I was thinking about dynamic help to trigger the change, but because it is a tabular presentation,
and with my limited knowledge, I think that maybe this isn't the right approach.

update of custom table one
Set a.field1 = b.field1, a.field2 = b.field2, a.field3 = b.field3

Hello
Whenever you have a problem, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) of all the tables involved, so that people who want to help you can recreate the problem and test their ideas.
Also post the exact results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.
If you ask yourself on a DML statement, such as UPDATE, then the CREATE TABLE and you post instructions INSERT must re - create the tables as they are to the DML, and the results will be the content of the or a modified tables when it's all over.
Simplify the problem as much as possible. For example, if your real problem involves 8 columns, try to post an issue affecting only 2 or 3 columns.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).
See the FAQ forum: Re: 2. How can I ask a question on the forums?

An example of the correct syntax for the use of a subquery in an UPDATE statement is:
UPDATE one
SET (Field1, Field2, Field2) =
(SELECT field1, Field2, field3
ABC
WHERE value = ' 05 "
);
This is a correct syntax, but I don't know if this will do exactly what you want, because I don't know exactly what you want.

update the table account via a form
Is this possible? To create a section of the E10 form, there isn't a way of conceiving the fields into account in the form.
We have an internal process to capture the customer account information on a quarterly cycle of our area reps. We would like to set up a form so that they can write to the table account, while having only not to change after submission.
Hello J,
You can move values across tables using rules of deduplication (for identical records) and managers (update record). Here are under Contacts > data tools > rules of deduplication. You are right that the forms will only allow you to update Contact fields, but you can add a processing step to your form 'Add program', where your program includes a step of type 'run a game/deduplication rule '.
That said, we recommend that you not data update CRM account Eloqua (I am not sure if that's your intention, but wanted to mention). Your CRM data into account should be the gold standard - data are updated only in that application and not by Eloqua or a different database. If you're just doing this for reporting purposes with Eloqua, it is fine, but you will notice that it didn't there no external call for 'update account' in Eloqua.
Hope that helps!
Thank you

Oracle 11g r2.
Try to write an SQL update.
Table USER_TAB
Primary key: user_id
Foreign key: account_id
Update user_tab
Set message_sent = 'Y '.
where account_id = 11111 and user_id = 2222 at the moment, I want to: set message_sent = null where account_id = 11111 and user_id! = 2222
So the final result will be:
USER_IS ACCOUNT_ID MESSAGE_SENT

3333 1111 [null]
4444 1111 [null]
5555 1111 [null]

Hello
So, sometimes you want message_sent be something and other time you want message_sent be anything else. This looks like a job for a CASE expression.
Here's one way:
UPDATE user_tab
Message_sent = BOX SET
WHEN user_id = 2222
THEN 'Y '.
NULL else - this is the default value, but it does not hurt to say explicitly
END
WHERE account_id = 1111 - 11111 or
AND user_id IS NOT NULL

Using the quick formula to update the pay_element_entry_values_f table
Hi friends
I have a requirement to substitute an input value of element with a value obtained from a quick formula.
I know that formula quick results used to fill the table pay_run_results and pay_run_result_values.
Is it possible that I can use the quick formula for updating the tables pay_element_entries_f and pay_element_entry_values_f
Thank you
Yes, you can do it.
Just call a formula within your formula and in the service function, you can write the pl/sql code you want.
So, you can use the input element in the pl/SQL API.
Just note that even if the input values are updated that are not considered payroll (at the time of execution of the payroll)
It would be only on the other (or additional payroll runs)

How can I update the data in mysql using the button defined in the table?
Hello
right now I am doing my project for the online election system using dreamweaver cc14. I create a table using php code to bind the data to mysql, and in this painting, I create also a button "vote" for voters to vote. My question is, how can I update my polling data in the mysql database when voters push button "vote" based on the id of the candidates? Here is my code I try:
<form method="post" id="form1"> <?php $servername = "localhost"; $username = "root"; $password = "pass"; $dbname = "ses"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT No, Calon, ID, Jurusan, Image FROM candidates"; $result = $conn->query($sql); if ($result->num_rows > 0) { echo "<table > <tr> <th>NO</th> <th>Candidate</th> <th>INFO</th> <th>Vote</th> </tr>"; // output data of each row while($row = $result->fetch_assoc()) { echo "<tr> <td>" . $row["No"]. "</td> <td><img src=" . $row['Image'] . "></td> <td><br/>-" . $row["Calon"]. " <br/>-" . $row["ID"]. " <br/>-" . $row["Jurusan"]. "<br/></td> <td><input type="."submit"." name=".$row["Calon"]." id=".$row["No"]. " value="."Vote"."></td> </tr>"; if(isset($_POST["".$row['No'].""])){ $vote_sachin = "UPDATE candidates SET Undi=Undi+1 WHERE No=".$row["No"]. ""; $run_sachin = mysqli_query($conn, $vote_sachin); } } echo "</table>"; } else { echo "0 results"; } $conn->close(); ?> </form>
I hope someone can help me in this area, because I'm still new in this programming language.
Thank you.
Youre probably going to insert a 'radio button' next to the names of candidates and recover the database ID of that (I guess that the ID is the primary key in your database that uniquely identifies each record.
His great confusion because you seem to update the database to aid WHERE no = "." $row ["no"]. so I don't know that ID is the primary key?
IF "No" IS your master database key, you need to change the code below:
TO:
Here's the complete code based on the ID of your primary database key.
<>
$servername = "localhost";
$username = 'root ';
$password = "pass";
$dbname = 'his ';
Create the connection
$conn = new mysqli ($dbname, $servername, $username, $password);
Check the connection
If {($conn-> connect_error)
Die ("connection failed:".) $conn-> connect_error);
}
$sql = "SELECT No, Calon, ID, Jurusan, Image OF candidates";
$result = $conn-> Query;
If you click on the button "vote" form run the code to update the database below
{if (isset($_POST['vote']))}
Get the value of the ID of the radio button form field and store it in a table.
$update_vote = $_POST ['candidate_id'];
loop in the table and update the database
foreach ($update_vote as $value) {}
$vote_sachin = ' candidates UPDATE SET Undi = Undi + 1 WHERE ID = ".". " $value. » « ;"
$run_sachin = mysqli_query ($conn, $vote_sachin);
}
