Update multiple rows using CASE WHEN

I have the table ACCOUNT of structure as follow:
ACCOUNT_ID
ACCOUNT_STATUS
004460721
2
042056291
5
601272065
3
I need to update the three rows at once using one SELECT statement such that, the second column will be 5, 3, 2 respectively.
I used the following query but seems there is something missing
UPDATE ACCOUNT
SET ACCOUNT_STATUS = CASE
WHEN ACCOUNT_STATUS = '004460721' THEN 5
WHEN ACCOUNT_STATUS = '042056291' THEN 3
WHEN ACCOUNT_STATUS = '601272065' THEN 2
WHERE ACCOUNT_ID IN ('004460721','042056291','601272065')
My question, is this way correct? if no, can I use CASE WHEN statement and how or I only have choice of using SUB-SELECT to acheive that in one statement?

What happens when you try it?
Did you mean "WHEN ACCOUNT_ID = ..."?
A CASE expressions always needs an END keyword.
Depending on your requirements (that is, why are those rows being changed, and how do you determine the new values) a CASE expression in an UPDATE statement, similar to what you posted, could be a good way to do it. MERGE (instead of UPDATE) would also be an option, especially if you want to avoid updating rows that already happen to have the correct values.

Update Multiple Rows using Row Selector

Hi,
I want to update multiple rows using a tabular form with row selector, and an item in another region of the page, using an update expression and a button.
The syntax would be like this:
update MY_TABLE set UPDATABLE_COLUMN = :P10_NEW_VALUE where {row selector = true}
What is the syntax for the WHERE clause, anyone knows? In the manual there is no information at all for doing this.
PD. I added the row selector after creating the form, so I don't have any wizard-created MRU processes in the page.
HTMLDB version is 1.6
Thanks.

How to return multiple rows in case when condition?

I want to display the list of product names owned by a company.If no products found it should return a string like "NO PRODUCTS FOUND'
The query I wrote working well but when the condition does not satisfy Its not returning "NO PRODUCTS FOUND''. Can someone help me how can I do this?
declare @Country varchar(100)='Netherlands'
SELECT CASE WHEN count(table4.ProductName) >0 THEN table4.ProductName
ELSE 'NO PRODUCTS FOUND' END AS Product_list
FROM table2 INNER JOIN
table1 ON table2.AccountID = table1.AccountID INNER JOIN
table3 ON table1.[company_ID] = table3.[company_ID] INNER JOIN
table4 ON table4.ProductID = table2.ProductID
WHERE
table1.[country] IN (@Country)) AND table4.ProductID IN (24410, 24413, 24418, 24383, 24384))
GROUP BY table4.ProductName

Your DDL does not match your query.
You also supplied no test data.
You're using INNER JOINS to enforce relationships that may not exist. You're using a WHERE clause to do the same.
Try this:
DECLARE @table1 TABLE (accountid int not null, productID varchar(20), company_id int)
DECLARE @table2 TABLE (accountid int not null, country varchar(20))
DECLARE @table3 TABLE (company_id int not null, company_name varchar(20))
DECLARE @table4 TABLE (productID int not null, productname varchar(20))
INSERT INTO @table2 (accountid, country) VALUES (1, 'Netherlands'),(2, 'Netherlands'),(3, 'Germany')
INSERT INTO @table1 (accountid, productID, company_id) VALUES (1,24410,1)
INSERT INTO @table3 (company_id, company_name) VALUES (1,'one company'),(2,'two company'),(3,'three company')
INSERT INTO @table4 (productID, productname) VALUES (24410,'a product')
DECLARE @Country varchar(100)='Netherlands'
SELECT t3.company_name,
CASE WHEN count(t4.ProductName) > 0 THEN t4.ProductName
ELSE 'NO PRODUCTS FOUND'
END AS Product_list
FROM @table2 t2
INNER JOIN @table3 t3
ON t2.accountid = t3.company_id
LEFT OUTER JOIN @table1 t1
ON t2.accountid = t1.accountid
LEFT OUTER JOIN @table4 t4
ON t1.productID = t4.productID
WHERE t2.country = @Country
GROUP BY t3.company_name, t4.productName

Updating multiple rows using join condition

Hi All,

I am trying to update first_last column in employees1 table. when i execute this procedure , i am getting the error

01427. 00000 - "single-row subquery returns more than one row"
Please let me know a solution for this.
Thanks,

Hello Manikandan,
in your inner SQL the resultset is not restricted to give just one row.
Try this
UPDATE hr.employees1 SET
FIRST_LAST= (select concat(FIRST_NAME,LAST_NAME) from hr.employees where emp_rec.EMPLOYEE_ID=hr.employees.employee_id);Your version did not have any restriction on the rows selected from hr.employees. You gave a where condition that is unrelated to the query.
The best solution for your problem is to avoid the PL/SQL loop completely. You could try something like this:
update
   (select
       e1.first_last,
       e.first_name,
       e.last_name
    from
       hr.employees1 e1,
       hr.employees e
    where
       e1.employee_id=e.employee_id) set
   first_last=first_name||last_name;But beware, updates on joins just work under some restrictions. The key of the table to be updated must be the key of the join. (key preserved is the word to look up.)
Hope that helps,
dhalek

Hi:
You have to make sure that join condition joins one record to one record not to a group of records.

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
10    2     5     19
11    3     1     15

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!

How to update multiple rows in one query using php

i am new to this can any one help me how to update multiple rows at a time i am doing an school attendance page

Often the situation is such that you have multiple courses across a range of dates.So students may take more than one course, and you need to track attendance for each course date. The following graphic demonstrates this:
In such a situation, you need four database tables as follows:
students (student_id, student_name, etc.)
courses (course_id, course_name, etc.)
students_courses (student_id, course_id)
attendance (student_id, course_id, dater)
A fifth table may also be needed to define the dates of courses, but you may also be able to build this array programmatically by using PHP's robust date functions, which can give you, for instance, all the Tuesdays and Thursdays between a start date and end date.
The students_courses table simply keeps track of which students are taking which courses, so it has just two columns for the primary keys of both of the main tables. The attendance table is similar, but it also includes a date field. The following view of the attendance table demonstrates this:
So if David's solution does cover your needs, consider yourself lucky, because this could quickly grow from a beginner-appropriate project to a moderately advanced one.

Update multiple rows in a dynamic table Dreamweaver CS5.5

hello there
i want to update multiple rows which comes from a dynamic table in Dreamweaver CS5 (a loop in php) here is my Mysql table :

<?php

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 multiple row for different values

hi,
Please provide me the sql query to update multiple row in a table with different values.
i need to change the old date to new date
we have only 3 column id,name,old date.now i need to update the old date to new date
ID name old date new date
1 A 2012-12-20 12/7/2012
2 B 2012-12-20 12/9/2012
3 c 2012-12-20 12/5/2012
thank you.

Here are two ways to do this. Thanks to ranit for the table creation script, which I adapted.create table test_x
as
select 1 id, 'A' name, to_date('2012-12-20','yyyy-mm-dd') old_date
from dual UNION ALL
select 2 id, 'B' name, to_date('2012-12-20','yyyy-mm-dd') old_date
from dual UNION ALL
SELECT 3 ID, 'C' NAME, TO_DATE('2012-12-20','yyyy-mm-dd') OLD_DATE
from dual;First method using MERGE:MERGE INTO TEST_X O
USING (
select 1 id, to_date('12/7/2012','mm/dd/yyyy') new_date
from dual UNION ALL
select 2 id, to_date('12/9/2012','mm/dd/yyyy') new_date
from dual UNION ALL
SELECT 3 ID, TO_DATE('12/5/2012','mm/dd/yyyy') NEW_DATE
FROM DUAL
) n
ON (O.ID = N.ID)
WHEN MATCHED THEN UPDATE SET OLD_DATE = n.NEW_DATE;Second method using UPDATE:UPDATE TEST_X SET OLD_DATE =
CASE WHEN ID = 1 THEN TO_DATE('12/7/2012','mm/dd/yyyy')
WHEN ID = 2 THEN TO_DATE('12/9/2012','mm/dd/yyyy')
WHEN ID = 3 THEN TO_DATE('12/5/2012','mm/dd/yyyy')
END
where id between 1 and 3;
You probably don't want to use these methods.*
You say the "user" will enter these values. Will he always enter exactly 3 values?
The "user" will enter values into a screen I suppose. What language is the user interface programmed in?

How to update multiple rows in ADF Tble

Hi,
I have created a search form and ADF table. This ADF table is having column of Select Boolean check box along with actual table columns.
When I click on Search button it should show the result in ADF table. I will be able to select the check box in multiple rows.
Finally when I click on Submit button status column should be updated against the rows for which Boolean check box is selected.
Here the thing that I would like to know is how to identify the rows whichever are selected when I click on Submit button.
Could you please help.
Regards
Vinod.

http://sameh-nassar.blogspot.de/2009/12/use-checkbox-for-selecting-multiple.html shows how to use a checkbox via a transient attribute on the EO. To get the selected row you check the transient attribute of each row.

Updating multiple rows with different values

Hi!
I have a problem. I need to update more then 1000 rows with different values. How can I do it?
For exsample i have table:
id; color, date,
1 red
2 green
3 white
I need to update date field.
Update table
set date='01.02.03'
where id=1
Update table
set date='01.03.03'
where id=2
Maybe there is way how to update multiple rows at one query?
Sorry for my bad english.
Thanks!

Hi,
You can try this
UPDATE TABLE SET DATE = CASE
                    WHEN ID = 1 THEN TO_DATE('01-02-03','DD-MM-RR')
                    WHEN ID = 2 THEN TO_DATE('01-03-03','DD-MM-RR')
                    ENDcheers

CMP update multiple rows

Hi,
Is there a way to update multiple rows when using CMPs.
For example I can update multiple rows by this method.
while (condition)
cmp = cmpHome.findByPrimaryKey(key);
cmp.setValue(newValue);
Rather than this method is there a way that I can update many rows just as normal sql update.
thanks in advance,
chamal.

If you want to concatenate Acol column with sysdate for 605 and 608 ....i think you need to code less (of what you have posted)
UPDATE TEST
SET TEST.ACOL = TEST.ACOL || ' ' ||sysdate
where
test.acol in (605,608);--I don't know why you want this , Just given the suggestion as per the requirement.

Want to update multiple rows of the report but getting a bug.

hi,
I am trying to update multiple rows of a report.For that I have created a teport with dynamic checkbox generated using ---HTMLDB_ITEM.CHECKBOX(1,utt.trouble_ticket_id) " "----.Checkboxes are rendered perfectly on the report.
but when I tried to update the selected rows of the report as given in the documentation
begin
:P16_priority:=htmldb_application.G_F01.count;
for i in 1..htmldb_application.G_F01.count
loop
update umanage_trouble_ticket set severity =:P16_priority where
trouble_ticket_id = htmldb_application.G_F01(i);
end loop;
end;
I found that all the rows are updated.not only selected rows.
and the count it gives =no of rows returned + no of rows selected.
Please help me regarding this.
thanx.
BHARAT

Hi Bernhard,
I think that u didnt get y problem.
When I take the value from "htmldb_application.g_f01(i)" then it should return id's of rows that are checked but when I do that it returns id's of all the rows.So I am not able to update only checked rows.
from id's of rows i mean value provided when generating checkboxes through query.
htmldb_item.checkbox(1,trouble_ticket_id) " "
I am approching to the solution as specified in the documentation. "Adding check boxes to each row in a report".
but still cant find any solution.
thanx that u showed some intrest in my problem.
If u can get the solution reply soon.
Regards
BHARAT

Updating Multiple Rows With A Sequence

I'm trying to update multiple rows of data in one column based on if its date is greater than a certain date. Starting with the lowest date from those dates I'll give it a 2000 and every ascending date from that point will be another number in sequence (2001, 2002, 2003, etc.).

I would use a counter and start at a specific number. Then I would try to keep updating with this number and incrementing each time. The part I can't quite grasp is how to use this number with the lowest record and apply this sequence to each date that ascends from there. What I was going to try to come up with is something like:
DECLARE
counter := 2000;
BEGIN
loop
update table_name
set column_name = counter
where date > specified date;
counter := counter + 1;
end loop;
This is my first thought but I couldn't see a way to just update the first one that is greater than the specified date and then keep cycling through the dates until the last date(most recent). I know I would need a loop but what can I set that loop to so it would know when to stop. I could use a variable I know is less than the total amount that need to be altered.
