Update multiple rows & columns using a single statement

I have the following table with tablename - emp
first_name last_name age
aaa bbb 31
56
78
ggg hhh 36
2nd & 3rd row contain null values (no data) in first_name & last_name column . I want to update those two rows with data using a single statement. How do I do it?
I was thinking may be something like the following:-
UPDATE emp
SET first_name= , last_name=
CASE
WHEN age = 56 THEN 'ccc', 'ddd'
WHEN age = 78 THEN 'eee', 'fff'
ELSE first_name, last_name
END
-----------------------------------------------

Can you give an example of a nested decode statement.

Extrapolate that to 255 components and you get 254 + 255 = 509 components. And so on...

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.

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 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?
update table tab_name
set date_time =date||time

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

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!

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.

Merging multiple rows in to a single row (when rows meet merging criteria)

Hi
I have a scenario to merge multiple rows in to a single rows when the data in those rows fall in merge criteria .Below is how my data is
Now the merging logic for the above rows is , we need to combine multiple rows in to a single row when the data in those rows permits us to do in that way. Simply saying , its like sandwich where we combine multiple things to a single piece.The output for
the above rows should be
Here we combined Row 1 ,2, 3 in to a single row as the data in those rows permits to merge in to single row. But the row 4 cannot be combined to any of those rows because the data in those rows doesn't permits us do a merge ( As the value of the column
JobSource for the row 4 is different from the other rows ) .
My original data has 56 columns , but for readability i kept only 9 columns.
can you please throw some idea on how to achieve this scenario. I know we need to use CTE for achieving this, but i am not able succeed in doing an iteration on multiple rows.
Appreciate your response .

Thanks for your reply .
Rule for merging is simple . First of all there is no unique row identifier for each row , the fact table is not having an identity column in the database . I called row 1 , row 2 etc in my post above only to make better explanation of my scenario.
The rule for merge is below.
1) we can combine only when the data in a column for one row is null & the data in same column for the other row is not null . It should also satisfy the condition where the data in other columns should conflict each other.
2) Data for all columns for the merging rows should not be conflicting (i.e. we should not merge the rows when the data in a column is not equal to the same column in the other row
,considering not null value)
Steps in merging the above source data :
1) Consider the case of row 1 and row 2 in the source, we can combine these rows as the data is satisfying the rule 1 for columns (Jobsource,Flight, Package,Update,Iscancelled
,Result, Severity) and columns (JobID and RuleName ) fall under rule 2. we merge these two rows in to a single row and keep in that in the table.
2) Then the resulting row is again merged with the second row which is present above by applying the rule 1 and rule 2 . Below would be output of merge operation.
Now there would be only two rows in the output . But these rows cannot be merged as the data doesn't satisfy the merge rules 2 . As Jobsource for the row 1 in the above output is "PresubmissionSource" which is not equal
to "PostSubmission" jobSource which is in row 2. So these two rows are left unmerged .So the above two rows would be the output of merge operation on my source data.
This process has to be repeated for all the rows in the table. As of now my table as 92 Million rows with 56 columns which need to be considered for merging rows. I replicated my scenario in 9 columns and 4 rows to understand better.

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?

Updating multiple rows

Hi,
I have a problem updating multiple rows.
I have the following update:
update POI.PERFTABLE p set P.PERF_3YEAR_ANNO =
(Select
PERF_ANNO_DAUER
rtrim(fs.match),
3
From POI.FONDSSTAMM fs ) where p.MATCH=match
but I become the error: ORA-01427: single-row subquery returns more than one row.
How must I write my SQL-Command that it works??????????
thanxx
Schoeib

Hhhhmmmmm,
-- So - this doesn't work .......
UPDATE POI.PERFTABLE p
SET     P.PERF_3YEAR_ANNO =
    (   SELECT PERF_ANNO_DAUER ( RTRIM( FS.Match ), 3 )
        FROM    POI.FONDSSTAMM fs
WHERE   P.Match = v_Match
-- Maybe - you could force the sub-select to return a single row.
UPDATE POI.PERFTABLE p
SET     P.PERF_3YEAR_ANNO =
    (   SELECT PERF_ANNO_DAUER ( RTRIM( FS.Match ), 3 )
        FROM    POI.FONDSSTAMM fs
        -- Restrict the sub-query to returning a single row.
        WHERE   FS.Some_ID = P.some_Id
WHERE   P.Match = v_Match
or even
-- Since you are using a function why not adjust the function,
-- or write a simular one, so that something like this would work.
UPDATE POI.PERFTABLE p
SET     P.PERF_3YEAR_ANNO = PERF_ANNO_DAUER ( RTRIM( P.Match ), 3 )
WHERE   P.Match = v_Match

Update multiple rows involving spatial data

Hi,
i have 2 table, that are
temp
store_id
store_state
geom mdsys.sdo_geometry
us_states
state
geom mdsys.sdo_geometry
i have indexed both table with spatial index.
If i wanna find state that temp.geom is inside us_states.geom using
SQL> select state from us_states, temp
where sdo_inside(temp.geom, us_states.geom) = 'TRUE';
it's work
but if i wanna update temp.store_state using
SQL> update temp set store_state = (select state from us_states
where sdo_inside(temp.geom, us_states.geom) = 'TRUE');
it gives this error
update temp set store_state = (select state from us_states where sdo_inside(temp.geom, us_states.geom) = 'TRUE')
ERROR at line 1:
ORA-13226: interface not supported without a spatial index
ORA-06512: at "MDSYS.MD", line 1723
ORA-06512: at "MDSYS.MDERR", line 8
ORA-06512: at "MDSYS.SDO_3GL", line 62
ORA-06512: at "MDSYS.SDO_3GL", line 192
any idea how can i update multiple rows that involving spatial data?
Thanks
Hadi

Hadi,
There are a number of things wrong with the second item. First up you most likely will return more than one row, which is not allowed as the = expects only one item.
Here is what I would use, which will update everything that meets the requirements, and ignore the rest:
UPDATE (
SELECT /*+ bypass_ujvc */
state, store_id, store_state
FROM temp, us_states
WHERE sdo_inside(temp.geom, us_states.geom) = 'TRUE')
SET store_state = state;
With the /*+ bypass_ujvc */ you're telling the db to not worry about requiring a "unique join view condition" -- which roughly mean "trust me, my rows are key preserved." This is important since there is really no "hard" key-based relationship to tie the two together.
However, unless you really think there are stores that border on two states, this will run much quicker with an anyinteract comparison.

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.

Updating multiples rows in a trigger

Hello All,
I need to update multiple rows in a table based on some condition, do you have any ideas doing it?
I know we can update single row using :NEW, but this time we need to update like 10 rows in a table.
Thanks in advance for your reply.

BC4J datagrid to update multiple rows

Hi,
How do we update multiple rows at a time in a BC4J JSP with Struts. I intend to have a datagrid control on a JSP so that users may update multiple rows at a time and click 'Update' once.
There is a possible (workaround) solution using struts nested tags but one would lose the benefits of JBO tags on using struts tags (e.g Calendar control would not be visible for Date input).
Any implementation suggestions?

Ashish
