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

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?

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.

Single Update command to update multiple rows with multiple rows

Hi Gurus!
Can I update table A with a result set of table b (multiple rows returns) where a.c1 = b.c1
regards,
SH

As Joel mentioned this update will update all rows in a table based on another one:
update tableA set seq_no = (select seqno from tableB where tableA.ID = tableB.ID)
Also, any rows that don't match the select criteria will get updated to null. This could be very bad depending on what you want to do.
To update a subset of tableA with data from tableB:
update tableA set seq_no = (select seqno from tableB where tableA.ID = tableB.ID)
where exists (select 1 from tableB where tableA.ID = tableB.ID)

Update multiple rows with datas from the same table

i have a table like
name version value1 value2
2 A 4,31 3,5
3 A 3,45 10
2 B 6,97 12
4 B 12 16
so name + version is unique
i have to update the datas value1 and value2 ( version A) with the datas from version B where the name ( VersionA) = name version B
i.e the result should be
name version value1 value2
2 A 6,97 12
3 A 3,45 10
2 B 6,97 12
4 B 12 16
is it possible to do this in sql? ( sql. 8.1)

... if your table does not contain exactly what you expect you could get:
'single row sub-query returns more than one row'
To prevent that, put a unique index on (name, version). If this combination is not always unique, you will need to cater for the possibility in the update statement.

Counting one of multiple rows with same value for same ID

Hello,
I have this query:
SELECT
count( case when EXISTS (
            SELECT *
            FROM business_log bl, subject su
            WHERE su.ID_SUBJECT = s.ID_SUBJECT
            and bl.id_subject = su.id_subject
            AND    bl.value = 'Solved'
then 1 else null end) num_solved
FROM subject s
It is posible that one subject is more than once 'Solved' in table BUSINESS_LOG
I want to count only one row solved for one subject.
I must to use only SUBJECT table in the main query because of other counts.
Thank You very much.
Regards
Milos

so in case you have no solved entry...you get NULL back instead of 0.....
and....there is no need for the group by ....as you are only looking for one subject
SELECT COALESCE((SELECT max(1)
                  FROM business_log bl
                 WHERE bl.id_subject = s.id_subject
                   AND bl.value = 'Solved'),0) num_solved
FROM subject s
but....I would like to have a proof, that this one is faster than the outer-join solution.
So...perhaps we'll see an execution plan for both of them.

Inserting multiple rows with 1 value of sequence

hi
need help again for my same school project
i need to insert the very 1 same value of a value which i get from a sequence/autocount(think of the situation like a point-of-sales where there is only 1 transaction no. for multiple items and not 1 for every single item sold)
eg. nextval generated by sequence is 2
transaction_no---item
2----------------01
2----------------02
2----------------03
and so on
i know i can't do it by seq_name.nextval because it will increment by 1 which i stated to increment by in d sequence
thank you!!!

you may try this:
First -- select seq_name.nextval from dual
Save it into some variable and the use in your inserts

Update multiple rows based on two columns in same row

I have a 1000 rows in a table I would like to update with a unique value. This unique value is a cocatenation of two columns in teh same row.
Each row has a (i) date and a (ii) time and a (iii) date_time column. I would like to update the date_time (iii) column with a cocatenation of the (i) date and (ii) time columns.
I know how I would update a single row but how can I update multiple rows with a cocatenation of each of the two columns - i.e put a different value into the date_time column for each row?

this?

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

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!

Deleting rows with missing values in field in start routine of update rule

Hello experts,
how can I delet rows with missing values in a specific field in the start routine of update rules?
I think ABAP code should look something like this:
delete ... from DATA_PACKAGE where Z_NO = ''.
thanks in advance for any suggestions!

Write:
delete data_package where field = value.
Hope it helps.

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...

Updating multiple rows in a table in ADF

Hi
How do we update multiple rows in a table.
Onclicking a update button the changed rows must be updated.

Hi Prince,
currently I am selecting one row from the table and rendering a region at the top of the table and capturing the user entered data with the following code:
ViewObjectVOImpl vo = getViewObjectVO1();
Row CurrentRow = vo.getCurrentRow();
//After this I perform the checks like user entered value is not null or check input as per business logic.
if(CurrentRow.getAttribute("attributeName") ==null){
//Add what message you want to display
//Add other business logic.
After making all the checks, i commit it.
getOADBTransaction().commit();
Now in my new page I am capturing the user input in the table itself like an excel sheet. Suppose there are ten rows in my advanced table on my page, and each row has one editable field. I have one save button at the bottom of the table.
Now on clicking the save button I have to capture the user input, check whether there is any null value and if all the entered data is correct then only I should commit it.
Can you please let me know how we can accomplish that.
Regards
Hawker
